    Japanese rock ptarmigans (Lagopus muta japonica) are birds that inhabit only alpine regions of central Honshu Island, Japan, known as the Japanese Alps. The number of these birds has recently declined, and in situ and ex situ national conservation programs for Japanese rock ptarmigans have been initiated. The infections of Eimeria spp. as protozoan parasites of the phylum Apicomplexa, E. uekii and E. raichoi, were frequently reported in the birds. However, the virulence of these Eimeria parasites has not been determined. Here, we analyzed the pathogenicity of these Eimeria parasites using experimental infections of a subspecies model of Japanese rock ptarmigans, Svalbard rock ptarmigans (Lagopus mutus hyperboreus), and evaluated acquired protective immunity against challenge in birds tolerant of low-dose inoculation with Eimeria parasites. Following inoculation with two Eimeria parasites derived from Japanese rock ptarmigans (dose range of 4 × 104 to 4 × 102 for E. uekii and 1.7 × 104 to 4 × 101 for E. raichoi), oocysts were detected at 6-8 days post-inoculation (PI), and the maximum number of oocysts per gram of feces was observed 7-10 days PI and then gradually decreased. The mortality rate and reduction in weight gain of chicks increased following high-dose inoculation of oocysts with abnormal feces (soft and diarrhea). Developmental zoites were detected histopathologically in epithelial tissues and sometimes the lamina propria from the duodenum to the colon. Chicks that survived low-dose inoculation did not show clear clinical symptoms after challenge inoculation. Our results suggest that the pathological characteristics of Eimeria parasites infecting Japanese rock ptarmigans include abnormal feces and reduction in weight gain, resulting in mortality in cases of heavy infection due to high-dose inoculation. These findings provide helpful data for Japanese rock ptarmigan conservation efforts.

    RNA activation (RNAa) is a burgeoning area of research in which double-stranded RNAs (dsRNAs) or small activating RNAs mediate the upregulation of specific genes by targeting the promoter sequence and/or AU-rich elements in the 3'- untranslated region (3'-UTR) of mRNA molecules. So far, studies on the phenomenon have been limited to mammals, plants, bacteria, Caenorhabditis elegans, and recently, Aedes aegypti. However, it is yet to be applied in other arthropods, including ticks, despite the ubiquitous presence of argonaute 2 protein, which is an indispensable requirement for the formation of RNA-induced transcriptional activation complex to enable a dsRNA-mediated gene activation. In this study, we demonstrated for the first time the possible presence of RNAa phenomenon in the tick vector, Haemaphysalis longicornis (Asian longhorned tick). We targeted the 3'-UTR of a novel endochitinase-like gene (HlemCHT) identified previously in H. longicornis eggs for dsRNA-mediated gene activation. Our results showed an increased gene expression in eggs of H. longicornis endochitinase-dsRNA-injected (dsHlemCHT) ticks on day-13 post-oviposition. Furthermore, we observed that eggs of dsHlemCHT ticks exhibited relatively early egg development and hatching, suggesting a dsRNA-mediated activation of the HlemCHT gene in the eggs. This is the first attempt to provide evidence of RNAa in ticks. Although further studies are required to elucidate the detailed mechanism by which RNAa occurs in ticks, the outcome of this study provides new opportunities for the use of RNAa as a gene overexpression tool in future studies on tick biology, to reduce the global burden of ticks and tick-borne diseases.

    PURPOSE: Eimeria spp. are commonly found among rabbits (Mammalia: Lagomorpha) worldwide. Among the 11 Eimeria species, several are highly virulent, including E. intestinalis and E. flavescens, which cause intestinal coccidiosis, and E. stiedae, which causes hepatic coccidiosis. Unlike other countries, the occurrence of Eimeria infections in rabbits in Japan remains unknown, except for one reported case of natural infection. METHODS: We surveyed Eimeria infections in clinically affected rabbits over the past approximately 10 years at Livestock Hygiene Centers in 42 prefectures. A total of 16 tissue samples (14 liver, 1 ileum, and 1 cecum) were collected from 15 rabbits in 6 prefectures. RESULTS: Characteristic histopathologic findings were observed, especially around the bile ducts, depending on the developmental stages of the parasites. Eimeria stiedae and E. flavescens were successfully identified by PCR and sequencing analyses in 5 liver samples and 1 cecum sample, respectively. CONCLUSION: Our results could enhance understanding of infection with Eimeria spp. in rabbits in Japan and contribute to pathological or molecular diagnoses.

    The present study aimed to evaluate the effects of 5-aminolevulinic acid (5-ALA) on Eimeria tenella infection in laying hens. Oocyst shedding and histopathology were evaluated. A reduced oocyst shedding was observed 5 and 7 days post-infection (dpi) in the 5-ALA-administered group, but the total number of oocysts during the first infection period was not different between control and 5-ALA-treated groups. After E. tenella attack infection, the period of oocyst shedding in the 5-ALA-administered group lasted less long than that in controls. During the attack infection period, the total number of fecal oocysts in the 5-ALA-treated group was significantly lower than that in the control group. However, the parasite burden score in hens receiving 5-ALA was higher than that in controls after E. tenella attack infection. The lesion scores at 5 and 30 dpi in the control group were significantly lower than those in the 5-ALA-administered group. Therefore, 5-ALA administration might be beneficial against E. tenella infection in laying hens.

    Among the 11 species of Eimeria in rabbits, some of which are known to be pathogenic and cause enteritis, E. stiedae induces severe liver lesions resulting in elevated mortality. Unlike in other countries, the incidence and prevalence of the parasites in rabbits have not been reported in Japan. In the present study, we histopathologically analyzed hepatic coccidiosis in a rabbit and attempted several primers to genetically identify the parasites and investigated the prevalence of Eimeria species at the same farm. In the liver of the affected rabbit, we observed fibrosis and edema around multiple bile ducts and epithelial cell hyperplasia of the bile ducts. Large numbers of developing parasites of Eimeria spp., mainly oocysts, were present in the bile ducts. PCR and sequencing analyses with the published primers for Cyclospora and Eimeria spp. were used to successfully identify the parasites in the liver as E. stiedae. The oocysts of Eimeria spp. were detected in 13 out of 20 fecal samples collected from other rabbits at the farm, and five Eimeria spp. (E. perforans, E. flavescens, E. exigua, E. magna, and E. vejdovskyi) were genetically confirmed. Our results provide the first indication that Eimeria spp., including highly pathogenic species, are present in Japan and the primer set used herein can be a useful tool for the identification of rabbit Eimeria spp.

    Secondary metabolites in plants influence the health of herbivores such as Japanese rock ptarmigans that feed on the leaves and fruits of alpine plants. Thus, it is important to understand the secondary metabolites of alpine plants and their biological activities for conserving Japanese rock ptarmigans. We isolated C-methylflavone from the leaves of Kalmia procumbens, on which Japanese rock ptarmigans feed. Although its structure was deduced to be 8-demethyleucalyptin by comparing its NMR data with the reported ones, the possibility that the isolated compound is 6-demethyleucalyptin cannot be ruled out. Thus, both isomers were synthesized. The isolated compound was unambiguously determined to be 8-demethyleucalyptin by comparing its NMR data with those of the synthetic ones. Cytotoxic evaluation of 8- and 6-demethyleucalyptins revealed that only the former showed cytotoxicity against HCT116 and MRC-5 cells. The present study provides not only easy access to 8- and 6-demethyleucalyptins, but also their biological information.

    Blood-feeding arthropods, particularly ticks and mosquitoes are considered the most important vectors of arthropod-borne diseases affecting humans and animals. While feeding on blood meals, arthropods are exposed to high levels of reactive oxygen species (ROS) since heme and other blood components can induce oxidative stress. Different ROS have important roles in interactions among the pathogens, vectors, and hosts. ROS influence various metabolic processes of the arthropods and some have detrimental effects. In this review, we investigate the various roles of ROS in these arthropods, including their innate immunity and the homeostasis of their microbiomes, that is, how ROS are utilized to maintain the balance between the natural microbiota and potential pathogens. We elucidate the mechanism of how ROS are utilized to fight off invading pathogens and how the arthropod-borne pathogens use the arthropods' antioxidant mechanism to defend against these ROS attacks and their possible impact on their vector potentials or their ability to acquire and transmit pathogens. In addition, we describe the possible roles of ROS in chemical insecticide/acaricide activity and/or in the development of resistance. Overall, this underscores the importance of the antioxidant system as a potential target for the control of arthropod and arthropod-borne pathogens.

    Cryptosporidium spp. are protozoan parasites that are transmitted via fecal-oral routes and can exhibit chemical resistance. Chlorine resistance makes it very difficult to eliminate parasites present in contaminated drinking water. While the efficacy of ultraviolet light-emitting diodes (UV-LEDs) against microorganisms has been reported, the efficacy of UV-LEDs against Cryptosporidium spp. has not been fully evaluated. Here, we assessed the efficacy of UV-LEDs with peak wavelengths of 268, 275, 284, and 289 nm against Cryptosporidium parvum at various exposure times, with a fixed exposure distance, using two in vitro methods. Consequently, the time required for 2 log10 inactivation through the excystation method by UV-LEDs of 268, 275, 284, and 289 nm was estimated as 115.5, 104.1, 37.4, and 30.7 min, respectively. The propidium iodide (PI) and 4',6-diamidino-2-phenylindole (DAPI) staining assays estimated the inactivation time as 311.3, 275.2, 60.6, and 39.1 min, respectively. Our results showed that UV-LED irradiation at longer wavelengths produced higher inactivation activity against C. parvum, which corroborates our previously reported in vivo assay results, although further study is needed to clarify the mechanism.

    We detected Eimeria oocysts from Japanese green pheasants (Phasianus versicolor) at a zoo in Osaka, Japan. The oocyst isolates were subspherical or ovoidal shaped and measured 17.2 (range 14.7-20.0) μm in length and 14.8 (13.3-16.7) μm in width with a length/width (L/W) ratio of 1.2 (1.0-1.4) and each had one polar granule. The oocysts lacked a residuum and micropyle. Sporocysts measured 9.8 (6.7-13.3) μm in length and 5.9 (4.7-7.3) μm in width, with a L/W ratio of 1.2 (1.1-1.4). Compared to previously published values, this strain shows morphological similarities with an isolate of E. teetartooimia from ring-necked pheasants from other countries. Phylogenetic analysis of the 18S rRNA and mitochondrial cytochrome c oxidase subunit I genes places the isolate in a clade related to chicken Eimeria spp., such as E. acervulina or E. brunetti. Although further analysis is needed, this information can be helpful for the diagnosis and determination of virulence of Eimeria spp. in pheasants.

    Japanese rock ptarmigans, Lagopus muta japonica, are classified as an endangered species in Japan and are found only in the Japanese Alps. The number of birds has decreased in the last half century and cage protection projects have been undertaken as in situ conservation strategies (one of the projects for the recovery plan of Japanese rock ptarmigan) in the mountains. During the period with cage protections, some chicks died and two Eimeria spp., E. uekii and E. raichoi, were identified in the chicks. Here, we examined the soil within the cages and in the surrounding environment to assess potential sources of infection between July to August 2020. We found high numbers of oocysts in the cages, especially at the back sides where the ptarmigan family frequently congregated, but soils in other areas outside the cages were less contaminated or not contaminated at all. The time required for more than 50% of the oocysts to sporulate at 15, 20 and 25 °C for E. uekii was 20, 11, and 5 h, respectively, and 72, 48 and 18 h, respectively, for E. raichoi. Our results cast some doubt that coprophagia by chicks is the source of infection because chicks consumed fresh cecal feces (approximately within 1 h) as far as we know, and instead, the protected chicks might be directly or indirectly infected by oocysts in soils or the environment.

    This study aimed to evaluate the disease severity and local immune responses in macrophage-depleted chicks with Eimeria tenella. Macrophages were reduced by intraperitoneal injection of a carrageenan solution at 12, 13, and 16 days old, whereas the control group received intraperitoneal phosphate-buffered saline. Both chick groups were orally inoculated with E. tenella sporulated oocysts at 14 days old. Feces were collected daily, which were then quantified for oocysts. The chicks were sacrificed on day 5, and the ceca were collected for histopathological observation. The gene expression levels were measured using real-time quantitative reverse transcription-polymerase chain reaction. Macrophage-depleted chicks have been observed to shed a significantly reduced number of fecal oocysts compared to the infected control group. The parasite burden score in cecum specimens of macrophage-depleted chicks was significantly lower than those of infected control on day 5 after infection. Furthermore, macrophage reduction yielded significantly lower cecum histopathological scores and CD4 expression than those of the infected control group. The expression of interleukin (IL)-18, IL-22, interferon-γ, and inducible nitric oxide synthase was also noted to be significantly upregulated in both infected control and macrophage-depleted chicks compared to uninfected chicks. IL-4, IL-13, IL-17, and perforin expressions were also higher with macrophage depletion than in both control groups. These results suggest that macrophages serve as an invasive gate or a transporting vehicle to the site of first merogony. Furthermore, mononuclear phagocytes may play an important role in local immune responses, thus contributing to parasite development during early E. tenella infection.

    The major clinical signs of coccidiosis in chickens due to Eimeria parasite are diarrhea and bloody feces. Previous studies showed that the impairment of the intestinal epithelial barrier and the elevation of the intestinal permeability are causes of clinical signs associated with coccidia challenges. Nevertheless, the information about molecular changes of the epithelial barrier at the early stage of the infection with a specific Eimeria species has not been mentioned. Hence, this study aims to elucidate the temporal relationships between epithelial barrier conditions and clinical signs in chickens infected with Eimeria tenella over the time from the earliest stages of infection. White Leghorn chickens were inoculated with 1 × 104 oocysts of E. tenella. Thereafter the chickens were monitored for their daily clinical signs through observation, and between 5 dpi to 10 dpi, feces were collected for oocysts counting. Chickens were then administrated with fluorescein isothiocyanate-dextran (FITC-d) for gastrointestinal permeability test and tissues were collected each day for histopathological observation and total RNA extraction. Finally, the mRNA expression levels of the tight and adherens junction genes and cytokine genes were evaluated using the quantitative real-time polymerase chain reaction (qRT-PCR). In this study, clinical signs such as diarrhea and bloody feces were observed concurrently from 3 to 8 dpi. Histopathology changes such as severe inflammation, hemorrhage, and epithelial desquamation were identified in the cecum specimens. The FITC-d level in the E. tenella-infected group was significantly higher than in the control group. In the infected group, the expression of claudin-2 gene was also upregulated, whereas the expressions of claudin-3 and E-cadherin genes were decreased as compared to the control group. These results implied that clinical signs of avian coccidiosis were associated with the intestinal barrier disruption via changes in expression levels of claudins and E-cadherin at the intestine.

    Dihydroorotate dehydrogenase (DHODH) is a mitochondrial monotopic membrane protein that plays an essential role in the pyrimidine de novo biosynthesis and electron transport chain pathways. In Eimeria tenella, an intracellular apicomplexan parasite that causes the most severe form of chicken coccidiosis, the activity of pyrimidine salvage pathway at the intracellular stage is negligible and it relies on the pyrimidine de novo biosynthesis pathway. Therefore, the enzymes of the de novo pathway are considered potential drug target candidates for the design of compounds with activity against this parasite. Although, DHODHs from E. tenella (EtDHODH), Plasmodium falciparum (PfDHODH), and human (HsDHODH) show distinct sensitivities to classical DHODH inhibitors, in this paper, we identify ferulenol as a potent inhibitor of both EtDHODH and HsDHODH. Additionally, we report the crystal structures of EtDHODH and HsDHODH in the absence and presence of ferulenol. Comparison of these enzymes showed that despite similar overall structures, the EtDHODH has a long insertion in the N-terminal helix region that assumes a disordered configuration. In addition, the crystal structures revealed that the ferulenol binding pocket of EtDHODH is larger than that of HsDHODH. These differences can be explored to accelerate structure-based design of inhibitors specifically targeting EtDHODH.

    As an alternative to using ultraviolet (UV) lamps, which are made with mercury that is toxic to the environment and human health, UV light-emitting diodes (UV-LEDs) are expected to be effective for inactivating microorganisms in water. Although UV-LEDs have been reported to be effective against bacteria and viruses, the effectiveness of UV-LEDs against Cryptosporidium parasites has not been fully evaluated. As we report here, we have developed an in vivo quantitative inactivation assay for C. parvum oocysts using immunodeficient mice. Using the assay, we evaluated the effectiveness of treatment by UV lamp (254 nm) at approximately 1000 μJ/cm2 (for 3 s at a distance of 95 mm) compared to inactivation by commercially available UV-LEDs (with peak wavelengths of 268, 275, 284, and 289 nm). The shed patterns of oocysts after treatment with 284- and 289-nm wavelength UV-LEDs were significantly delayed compared to that after treatment with a UV lamp. These findings provide the first suggestion that UV-LEDs are effective against these parasites, as assessed using commercially available 350-mA UV-LEDs under conditions of fixed exposure distance and time.

    The population of Japanese rock ptarmigan (Lagopus muta japonica), an endangered species with a habitat above the timberline of the southern Japanese Alps, has declined. As one of the recent conservation strategies for this species, cage protection for broods (hens and chicks) has been introduced in their habitats. Two species of Eimeria have frequently been detected in these birds, but little is known about the parasitic circulation in the region, including among birds and in the environment. Here, we conducted histopathology examinations of dead chicks collected under cage protection in 2018, and examined the feces of the hens and chicks of three broods and environmental soils for parasites in 2019 in order to assess the potential sources of infection and pathogenicity. Developmental zoites were found in the epithelial mucosa and/or the submucosa from the duodenum to the colon of all dead chicks. Fecal examination revealed oocysts of E. uekii and/or E. raichoi in all hens and chicks. Oocysts of Eimeria spp. per gram of feces in chicks increased within 2 weeks after hatching and then gradually deceased. Following infection of the chicks, oocysts could accumulate within the cage areas, and oocyst density exceeded more than 1000 oocysts per gram of cage soils. Based on having sporulated morphologies, oocysts could be infective and therefore, be direct or indirect potential sources of infection. However, based on our findings that not all chicks were clinically affected by the infections, other factors such as microbial flora in the chicks established by coprophagy or from the habitat environment, including climate, might be associated with the pathogenicity of Eimeria spp., although further studies are needed to assess these correlations.

    Entamoeba suis and E. polecki subtype (ST) 1 and ST3 recently have been inferred to be virulent in pigs. However, because relevant molecular epidemiological surveys have been limited, the prevalences of these species remain unknown and their pathogenicities are still controversial. We surveyed 196 fecal samples of pigs (118 of adults, 78 of piglets) at Tangerang in West Java, Indonesia, in 2017, employing PCR using porcine Entamoeba-specific primers. E. suis was the more frequently detected species, observed in 81.1% of samples, while E. polecki ST1 and ST3 were detected in 18.4% and 17.3% of samples, respectively; mixed infections (harboring 2-3 species or subtypes of Entamoeba) were confirmed in 29.3% of positive samples. Statistically significant differences in the positive rates were not seen between adult pigs and piglets, except for those of E. polecki ST3. The prevalences of Eimeria spp. and/or Cystoisospora suis (79.1%), strongyles (55.6%), and Strongyloides spp. (6.1%) were also observed morphologically in the samples. Further chronological or seasonal investigations of pigs and humans in these high-prevalence areas are needed to assess the virulence of the Entamoeba parasites, including the effects on pig productivity, and to evaluate the zoonotic impacts of these organisms.

    There have been no reports of the prevalence of Eimeria spp. in poultry breeding farms in Japan unlike those of broiler farms. From 2017 to 2018, we examined the prevalence of Eimeria spp. on breeding farms in Japan by oocyst morphology and PCR analyses. A total of 143 samples was collected from 37 breeding farms in 21 prefectures of Japan. We detected oocysts of seven species at 34 of 37 breeding farms by PCR, and we identified E. brunetti at 51.5% of farms found to be positive for Eimeria. The differences in the identification of Eimeria spp. between the morphology and PCR assay methods of oocysts were pronounced for E. maxima and E. necatrix. We confirmed that molecular tools were more suitable for accurately estimating prevalence of Eimeria spp., and these findings suggest that E. brunetti could be widespread in Japan.

    Piglets aged approximately 50 days exhibited diarrhea and wasting. Multiple white foci were detected in the colon of a dead piglet; histopathological findings revealed multifocal ulcers and crypt abscesses with Entamoeba trophozoites and gram-negative bacilli in the piglet. These pathogens were identified as Entamoeba polecki subtype 3 and Salmonella enterica serovar Typhimurium, respectively. Numerous E. polecki subtype 3 trophozoites were located on the edge of the ulcerative and necrotic lesions in the lamina propria. Crypt abscesses were associated with S. Typhimurium. These results suggest that E. polecki subtype 3 caused multifocal ulcerative colitis accompanied by crypt abscesses with S. Typhimurium in the piglet. This study is the first report of colitis with E. polecki subtype 3 and S. Typhimurium coinfection.

    To date, more than 50 Eimeria spp. have been isolated from marsupials of the family Macropodidae. Although 18 species of Eimeria have been previously detected from multiple animal species belonging to the genus Macropus of the family, limited genetic analyses of the parasites are available, and their pathogenicity remains unclear. Here, we report the isolation of Eimeria spp. from a zoo specimen of red-necked wallaby (Macropodidae; Macropus rufogriseus). Specifically, two distinct types of Eimeria oocysts were recovered, one from the feces before treatment with an anthelmintic and the second from the intestinal contents after death of the animal. The oocysts obtained from the two sources were morphologically identified as E. hestermani and E. prionotemni, respectively. We successfully determined partial gene sequences from the two isolates, including segments of the 18S rRNA genes, and for the first time have used phylogenetic analyses of these sequences to assign the species to distinct clades. In combination with further genetic data, these results are expected to help elucidate the pathogenicity and host ranges of Eimeria spp. within the respective family and genus.

    Gastrointestinal parasites can induce low productivity in livestock by causing acute or chronic enteritis. Veterinarians make great efforts to design rational and effective hygienic protocols for both the prevention and treatment of diarrhea. Although prevalences can vary depending on the examined areas or the ages of the hosts, and the methods used for detections, it is helpful to accumulate data across many areas to evaluate parasitic distribution. A coprological survey in cattle was conducted in Tangerang, Banten Province of Indonesia, in order to determine the prevalence of the parasites, including those of diarrhea-associated diseases. Furthermore, the risk of transmission of Giardia intestinalis and Cryptosporidium spp. to human was genetically analyzed. Gastrointestinal parasites were detected in 87 of 109 cattle samples, including 85 carrying Eimeria spp., 36 carrying Fasciola gigantica, 35 carrying Strongyloides spp., 33 carrying Paramphistomum spp., and 15 carrying Capillaria spp. Giardia intestinalis and Cryptosporidium spp., parasites with zoonotic potential, were detected in 9 and 1 cattle samples, respectively. Molecular analyses identified the G. intestinalis isolate as a member of Assemblage E, which has been recently detected in humans in another country. These results may be helpful in understanding the hygienic risk affecting the livestock productivity and zoonotic potential of cattle in Indonesia.

    BACKGROUND: The genus Onchocerca Diesing, 1841 includes species of medical importance, such as O. volvulus (Leuckart, 1893), which causes river blindness in the tropics. Recently, zoonotic onchocercosis has been reported in humans worldwide. In Japan, O. dewittei japonica Uni, Bain & Takaoka, 2001 from wild boars is a causative agent for this zoonosis. Many filarioid nematodes are infected with Wolbachia endosymbionts which exhibit various evolutionary relationships with their hosts. While investigating the filarial fauna of Borneo, we discovered an undescribed Onchocerca species in the bearded pig Sus barbatus Müller (Cetartiodactyla: Suidae). METHODS: We isolated Onchocerca specimens from bearded pigs and examined their morphology. For comparative material, we collected fresh specimens of O. d. dewittei Bain, Ramachandran, Petter & Mak, 1977 from banded pigs (S. scrofa vittatus Boie) in Peninsular Malaysia. Partial sequences of three different genes (two mitochondrial genes, cox1 and 12S rRNA, and one nuclear ITS region) of these filarioids were analysed. By multi-locus sequence analyses based on six genes (16S rDNA, ftsZ, dnaA, coxA, fbpA and gatB) of Wolbachia, we determined the supergroups in the specimens from bearded pigs and those of O. d. dewittei. RESULTS: Onchocerca borneensis Uni, Mat Udin & Takaoka n. sp. is described on the basis of morphological characteristics and its genetic divergence from congeners. Molecular characteristics of the new species revealed its close evolutionary relationship with O. d. dewittei. Calculated p-distance for the cox1 gene sequences between O. borneensis n. sp. and O. d. dewittei was 5.9%, while that between O. d. dewittei and O. d. japonica was 7.6%. No intraspecific genetic variation was found for the new species. Wolbachia strains identified in the new species and O. d. dewittei belonged to supergroup C and are closely related. CONCLUSIONS: Our molecular analyses of filarioids from Asian suids indicate that the new species is sister to O. d. dewittei. On the basis of its morphological and molecular characteristics, we propose to elevate O. d. japonica to species level as O. japonica Uni, Bain & Takaoka, 2001. Coevolutionary relationships exist between the Wolbachia strains and their filarial hosts in Borneo and Peninsular Malaysia.

    Attenuated strains of avian Eimeria parasites, generated by the selection of precocious lines through serial passaging in chicks, have been used widely as live vaccines. Detailed morphological transitions including their life cycle depending on the passages remain poorly understood. Here, we showed early development and acceleration of transitions in morphological forms of the asexual schizonts of E. tenella that had been attenuated for virulence by serial passaging. Our results may be helpful in understanding parasitism, facilitating further molecular analyses such as comparative genomic or transcriptomic tests.

    Gastrointestinal parasites including Eimeria spp. are known to affect domestic animal productivity causing watery or lethal bloody diarrhea. However, there are few reports on the detailed distribution of bovine Eimeria spp. in cattle, particularly in developing tropical and sub-tropical areas. Using a total of 289 fecal samples collected from beef cattle on Java Island, one of the five main islands of Indonesia, fecal examinations by the Whitlock and sugar flotation methods and molecular surveys were conducted to reveal the prevalence of 6 Eimeria spp. As a result of morphological screening using Whitlock methods and sugar flotation, Eimeria spp. prevalences of 9.4% and 52.3% were confirmed, respectively. The prevalence was higher in younger cattle [under 1 year (63.9%), 1-2 years (75.0%) and more than in 2 year old cattle (42.3%)]. The prevalences of identified species were as follows: 10.4% for E. bovis, 2.8% for E. ellipsoidalis, 2.1% for E. alabamensis, 1.4% for E. zuernii, 1.1% for E. auburnensis, and 0.4% for E. cylindrica. Moreover, prevalences of 12.8% for Strongyloides papillosus, 7.3% for Trichuris globulosa, and 0.3% for Capillaria bovis were detected. Although the average number of oocysts per gram of feces was <100 among the positive samples, and cases of heavy infection were limited, the endemicity of these pathogenic Eimeria species among farms in Indonesia should be noted.

    INTRODUCTION: Murine Eimeria spp. have been used as effective experimental models of disease instead of large mammalian hosts such as cattle. We here examine drug susceptibility of the uncharacterized murine intestinal protozoan parasite, Eimeria krijgsmanni. MATERIALS AND METHODS: The effectiveness of different treatments against infection of E. krijgsmanni was examined for suppression of oocyst shedding: ST mixture ST mixture, pyrimethamine, Ektecin and toltrazuril. RESULTS: ST mixture and pyrimethamine did not suppress oocyst shedding effectively. Although therapeutic efficacy of Ektecin was demonstrated, the dose required was larger than that for cattle and chickens. Oocyst shedding was only completely suppressed completely by continuous administration of toltrazuril. Furthermore, it was confirmed through morphological examination that early developmental stage zoites appeared in host epithelial cells during and following treatment by toltrazuril, and toltrazuril could not eliminate residual zoites in epithelial cells. CONCLUSION: E. krijgsmanni may be relatively resistant to these anti-coccidian agents and might therefore have different characteristics that differ from other coccidia with regard to drug susceptibility.

    Retortamonas spp. has been reported as an intestinal parasite among various host organisms, including humans; however, its intra-genus molecular diversity has not yet been elucidated. Haplotypes of the 18S small subunit ribosomal RNA locus (1836-1899 bp) of Retortamonas spp. from humans (n = 8), pigs (n = 6), dogs (n = 1), goats (n = 16), water buffalos (n = 23), cattle (n = 7), rats (n = 3), and chickens (n = 5) were analyzed with references isolated from non-human mammals, amphibians, and insects. Phylogenetic and network analyses revealed a statistically supported three cluster formation among the vertebrate-isolated haplotypes, while insect-isolated haplotypes were independently clustered with Chilomastix. In the clade of vertebrate isolates, assemblage A (amphibian genotype), which included the amphibian references, was addressed as an out-group of the other clusters. Assemblage B (mammalian and chicken genotype) included most haplotypes from various mammals including humans with the haplotypes isolated from a chicken. Human isolates were all classified into this assemblage, thus assemblage B might correspond to R. intestinalis. Assemblage C (bovine genotype), which included specific haplotypes from water buffalos and cattle, was addressed as a sister lineage of assemblage B. Among the diversified haplotypes of assemblage B, a specific haplotype, which was identified from multiple host mammals (humans, dogs, pigs, cattle, water buffalos, elks, goats, and rats), indicates the potential zoonotic transmission of the Retortamonas among them. The genotyping classification of retortamonads could contribute to a better understanding of its molecular epidemiology, especially among humans and related host organisms.

    OBJECTIVES: Feline gingivostomatitis (FGS) is a painful chronic inflammatory disease of the oral cavity. The purpose of this study was to examine the frequency of detection of certain common feline bacteria and viruses to determine any potential associations with FGS. METHODS: A multicentre case-control study design was conducted. In total, 72 control cats and 32 cats with FGS were included in the study. Oral swabs were cultured for bacterial identification and a PCR assay was carried out to examine the infection of feline calicivirus (FCV), feline herpesvirus-1 (FHV-1), Chlamydia felis, Mycoplasma felis and Bordetella bronchiseptica. RESULTS: There was a significant difference in age distribution between the control and the FGS group. Based on a PCR assay, the positive rate of FCV was significantly higher in FGS cats than control animals. For other infectious pathogens, including FHV-1, C felis and M felis, there was no significant difference. Bacterial culture of oral swabs revealed that Pasteurella multocida was most frequently detected, but the detection rate was significantly lower in FGS cats. In FGS cats, the incidence of Enterococcus faecalis and anaerobic bacteria were more frequently isolated than in control cats. CONCLUSIONS AND RELEVANCE: This study indicates that the positive rate of FCV was significantly higher in cats with FGS, and the microflora of the oral cavity of cats with FGS might be disrupted, although additional studies are required to compare the oral microbiome in cats of a variety of ages.

    Eimeria tenella is an intracellular apicomplexan parasite, which infects cecal epithelial cells from chickens and causes hemorrhagic diarrhea and eventual death. We have previously reported the comparative RNA sequence analysis of the E. tenella sporozoite stage between virulent and precocious strains and showed that the expression of several genes involved in mitochondrial electron transport chain (ETC), such as type II NADH dehydrogenase (NDH-2), complex II (succinate:quinone oxidoreductase), malate:quinone oxidoreductase (MQO), and glycerol-3-phosphate dehydrogenase (G3PDH), were upregulated in virulent strain. To study E. tenella mitochondrial ETC in detail, we developed a reproducible method for preparation of mitochondria-rich fraction from sporozoites, which maintained high specific activities of dehydrogenases, such as NDH-2 followed by G3PDH, MQO, complex II, and dihydroorotate dehydrogenase (DHODH). Of particular importance, we showed that E. tenella sporozoite mitochondria possess an intrinsic ability to perform fumarate respiration (via complex II) in addition to the classical oxygen respiration (via complexes III and IV). Further analysis by high-resolution clear native electrophoresis, activity staining, and nano-liquid chromatography tandem-mass spectrometry (nano-LC-MS/MS) provided evidence of a mitochondrial complex II-III-IV supercomplex. Our analysis suggests that complex II from E. tenella has biochemical features distinct to known orthologues and is a potential target for the development of new anticoccidian drugs.

    Giardia intestinalisとEntamoeba種の病原性を評価した。学校ベースで横断的検体採取を行った。健康な学齢児144名(男児74名、年齢7～15歳)から便を採取し、ブリストル便形状スケールにしたがって7段階のスコアに分類した後、便秘便(スコア1～2)、正常便(3～4)、軟便(5～7)に区分した。便からDNAを抽出し、G.intestinalis、Entamoeba種の18S rRNAを標的としたPCRを行った。各原虫の陽性率は、G.intestinalis(56.3%)、E.histolytica(0%)、E.dispar(6.9%)、E.moshkovskii(0%)、E.hartmanni(31.3%)、E.coli(44.4%)であった。各原虫陽性便の軟便率はG.intestinalis(66.7%)、E.dispar(80.0%)、E.hartmanni(68.9%)、E.coli(64.1%)であった。ロジスティック回帰分析により、軟便とE.hartmanni定着の間にのみ相関が認められた(AOR 2.81,95%CI:1.1～3.7,p=0.026)。流行地の7歳以上の小児においてはG.intestinalisは共生原虫とみなされると推測された。E.hartmanniはスコア5の便から検出されたことから、病原性は軽度なものに限られると考えられた。

    © 2019, Japan International Research Center for Agricultural Sciences. Postweaning diarrhea and wasting are a major concern in pig farms' management. Although hemolytic enterotoxigenic Escherichia coli, porcine epidemic diarrhea virus, porcine circovirus type 2, and Salmonella spp. are the most frequent etiological agents of these diseases, Entamoeba suis and E. polecki were recently reported to be associated with diarrhea in pigs. Since the infection rate of Entamoeba in pigs and its relationship with other pathogens are unknown, we examined 206 pigs exhibiting diarrhea and/or wasting in Aichi Prefecture, Japan to determine the prevalence of porcine Entamoeba spp. E. suis- and E. polecki-like trophozoites were detected by histopathology in 53 pigs, mainly in the lumen of the large intestine. Ulcerative colitis with infiltrating trophozoites was observed in 16 pigs, and most of these trophozoites were identified as E. polecki subtype 3 by PCR and sequence analysis. Tissue-invasive Entamoeba spp. were prevalent in pigs exhibiting diarrhea and wasting, and most samples were also positive for either Salmonella spp. or Lawsonia intracellularis by immunohistochemistry. These results suggested that Entamoeba was widespread in farms in Aichi Prefecture, and in most cases, enteritis was caused by coinfection by Entamoeba with Salmonella spp. or L. intracellularis, which causes wasting by exacerbating the original mucosal lesions.

    Background: Although parasites are still endemic in developing areas, residents in those regions seem not to be affected by the presence of intestinal protozoans. This study aimed to investigate whether pathogenic and commensal protozoans are the causal agents of diarrhea via a school-based cross-sectional survey conducted in Indonesia, in September 2016. Results: Molecular screening for intestinal protozoans in collected 144 stool samples from healthy students (age range 7-15 years) was carried out. The prevalence of protozoan parasites was as follows: Giardia intestinalis (56.3%), Entamoeba histolytica (0%), E. dispar (6.9%), E. moshkovskii (0%), E. hartmanni (31.3%), and E. coli (44.4%). Observational evaluation of stool conditions using the Bristol stool chart confirmed the loose stool rate (33.3-90.9%) in each age group. Logistic regression analysis of protozoan infection or colonization for loose stool (mild to severe diarrhea) as an outcome revealed no significant findings in examined protozoans including pathogenic G. intestinalis infection [adjusted odds ratio (AOR) 0.78, 95% confidence interval (CI) 0.36-1.67], except in E. hartmanni colonization (AOR 2.81, 95% CI 1.1-3.7, P = 0.026). Conclusions: The molecular survey of intestinal protozoans targeting healthy population with their stool form evaluation could address the pathogenicity of those parasites appropriately. In comparatively higher-age children at least 7 years of age or greater in the endemic area, G. intestinalis could regard commensal, while E. hartmanni seems to possess a certain pathogenicity as a causal agent of mild diarrhea.
