    BACKGROUND: Klebsiella pneumoniae strains pose a significant threat to public health. Currently, it is inconclusive whether hypermucoviscous K. pneumoniae (hmKp; semi-quantitatively defined by a positive 'string test') bacteraemia is clinically more severe than non-hmKp bacteraemia. Hence, this systematic review and meta-analysis was conducted with the aim of drawing some conclusions on hypermucoviscosity and bacteraemia. METHODS: PubMed and Web of Science databases were searched for all relevant publications from January 2000 to March 2022. The outcome measures were mortality rate and abscess formation. RESULTS: Fourteen observational studies were included in this systematic review, comprising a total of 3092 patients with K. pneumoniae bacteraemia, including 746 (24.1%) patients with hmKp strains. The meta-analysis showed that hmKp bacteraemia did not account for a significant increase in the incidence of all-cause mortality compared with non-hmKp bacteraemia [pooled hazard ratio 1.30, 95% confidence interval (CI) 0.79-2.12; P=0.30]. However, hmKp bacteraemia was associated with a significant increase in the incidence of abscess formation compared with non-hmKp bacteraemia (pooled odds ratio 7.74, 95% CI 4.96-12.06; P<0.00001). CONCLUSIONS: Although mortality may not be dependent on the causative agent, this review reaffirms the importance of the string test to detect hmKp. There is a need for prudent management, especially for patients with hmKp, that should include investigations for liver abscess and/or metastatic spread, and measures for early and proper source control as this can improve the prognosis.

    BACKGROUND: Hypervirulent Klebsiella pneumoniae (hvKp) infections confer notable morbidity and mortality. Differential diagnosis to determine whether the infections are caused by either the hvKp or classical K. pneumoniae (cKp) strain is particularly important for undertaking optimal clinical care and infection control efforts. AIM: To identify and assess the potential predictors of hvKp infections. METHODS: PubMed, Web of Science, and Cochrane Library databases were searched for all relevant publications from January 2000 to March 2022. The search terms included a combination of the following terms: (i) Klebsiella pneumoniae or K. pneumoniae and (ii) hypervirulent or hypervirulence. A meta-analysis of factors for which risk ratio was reported in three or more studies was conducted, and at least one statistically significant association was identified. FINDINGS: In this systematic review of 11 observational studies, a total of 1392 patients with K. pneumoniae infection and 596 (42.8%) with hvKp strains were evaluated. In the meta-analysis, diabetes mellitus and liver abscess (pooled risk ratio: 2.61 (95% confidence interval: 1.79-3.80) and 9.04 (2.58-31.72), respectively; all P < 0.001) were predictors of hvKp infections. CONCLUSION: For patients with a history of the abovementioned predictors, prudent management, including the search for multiple sites of infection and/or metastatic spread and the enforcement of an early and appropriate source control procedure, should be initiated in consideration of the potential presence of hvKp. We believe that this research highlights the urgent need for increasing clinical awareness of the management of hvKp infections.

    OBJECTIVES: In hypervirulent Klebsiella pneumoniae (hvKP), the hypermucoviscous capsule is known to be a major virulence determinant. We previously discovered that rifampicin (RFP), a bactericidal drug that binds to and inhibits the β subunit of RNA polymerase (RpoB), elicits anti-mucoviscous activity against hvKP by suppressing rmpA, a regulator of capsule production. Here, we aimed to determine whether RFP exerts this effect at sub-growth-inhibitory concentrations via its binding to RpoB. METHODS: Five spontaneous RFP-resistant mutants (R1-R5) were prepared from an hvKP clinical isolate and subjected to whole genome sequencing and mucoviscosity analyses. Subsequently, a two-step allelic exchange procedure was used to create a rpoB mutant R6 and revertants with wild-type rpoB from R1-R5 (named R1'-R5'). Transcription levels of rmpA and the capsular polysaccharide polymerase gene magA and capsule thickness of R1-R5 and R1'-R5' grown without or with RFP were evaluated by quantitative reverse transcription polymerase chain reaction and microscopic observation using India ink staining. RESULTS: R1-R5 all had non-synonymous point mutations in rpoB and were highly resistant to the bactericidal effects and anti-mucoviscous activity of RFP. While the properties of R6 were similar to those of R1-R5, the responses of R1'-R5' to RFP were identical to those of the wild type. rmpA and magA transcription levels and capsule thickness correlated well with the mucoviscosity levels. CONCLUSIONS: RFP exerts anti-mucoviscous activity by binding to RpoB. The mechanism of how this causes rmpA suppression remains to be explored.

    OBJECTIVE: Most non-tuberculous mycobacteria exhibit intrinsic resistance against the anti-tuberculosis drug isoniazid (INH). We previously found that a pyrazinamidase/nicotinamidase of Mycobacterium smegmatis, named PzaA, has an enzymatic activity to hydrolyze INH, which may contribute to intrinsic resistance. Furthermore, PzaA expression is strongly induced by INH under nitrogen-depleted conditions, although the precise mechanism of this phenomenon remains unclear. Here, we aimed to reveal the mechanism underlying the INH-dependent induction of PzaA using a transcriptomic approach. METHODS: RNA sequencing was performed to identify INH-inducible genes other than pzaA. 5' rapid amplification of cDNA ends analysis was employed to identify the transcription start sites of INH-induced transcription units. The function of a LuxR-like regulator gene (MSMEI_1050) found within the gene cluster containing pzaA was confirmed by gene deletion and complementation experiments involving INH hydrolysis assay and quantitative reverse transcription PCR. RESULTS: RNA sequencing revealed 23 genes that INH strongly induced under conditions of nitrogen depletion, 17 of which were in a gene cluster containing pzaA. This cluster comprised at least three transcription units, including a non-INH-inducible monocistronic unit containing MSMEI_1050. Deletion of this gene deprived M. smegmatis of the ability to respond to INH, and complementation restored this ability. CONCLUSIONS: MSMEI_1050 plays a key role in INH-dependent gene regulation. The precise mechanism of action is to be determined in future studies.

    BACKGROUND/PURPOSE: Klebsiella pneumoniae bacteremia-induced sepsis is a clinically important condition with a high mortality rate and various known virulence factors. However, studies on the association of these virulence factors with the occurrence of K. pneumoniae bacteremia-induced sepsis are scarce. We aimed to investigate clinical variables and virulence factors in patients with K. pneumoniae bacteremia-induced sepsis. METHODS: We retrospectively reviewed the medical records of 76 patients with K. pneumoniae bacteremia between January 2012 and July 2017. Patients were divided into sepsis (n = 25) and non-sepsis (n = 51) groups. Patient background characteristics, antimicrobial regimens, and prognosis were evaluated. We assessed the distribution of virulence factors related to K. pneumoniae, such as mucoviscosity, capsular polysaccharide, and siderophores. Siderophore production levels were determined by measuring the orange halo zone on chrome azurol S agar plate assay. RESULTS: There were no intergroup differences in male-to-female ratio and age. Multivariable analysis revealed that siderophore production level (p < 0.01) was an independent predictor of K. pneumoniae bacteremia-induced sepsis. Furthermore, the optimal cut-off point of siderophore production to predict sepsis was 9.6 mm (sensitivity, 86%; specificity, 76%; AUC, 0.81). CONCLUSION: Siderophore production was an independent predictor of sepsis caused by K. pneumoniae bacteremia. The optimal cut-off point for siderophore production for sepsis occurrence prediction was 9.6 mm. To improve outcomes, patients with K. pneumoniae bacteremia-induced sepsis with high siderophore production levels should be managed prudently.

    <title>Abstract</title>
    <sec>
    <title>Objectives</title>
    To characterize Acinetobacter baumannii OCU_Ac16a, a clinical isolate co-harbouring three acquired carbapenemase genes, blaNDM-1, blaTMB-1, and blaOXA-58, and assess the clinical significance of so-called multiple-carbapenemase producers.


    </sec>
    <sec>
    <title>Methods</title>
    OCU_Ac16a and its close relative, OCU_Ac16b, which lacks the blaNDM-1, were isolated from sputum cultures of a patient at Osaka City University Hospital. We subjected these strains to whole-genome analysis, particularly focusing on the genetic context of each carbapenemase gene. The transmissibility and functionality of each carbapenemase gene were analysed by conjugation and transformation experiments and antimicrobial susceptibility tests.


    </sec>
    <sec>
    <title>Results</title>
    bla TMB-1 was located in a class 1 integron on the chromosome, whereas blaNDM-1 and blaOXA-58 were found on plasmids named pOCU_Ac16a_2 and pOCU_Ac16a_3, respectively. pOCU_Ac16a_2 (which exhibited highly efficient self-transmissibility) and pOCU_Ac16a_3 (which did not show transmissibility but could be introduced into another A. baumannii strain via electroporation) could both confer carbapenem resistance (MICs ≥512 and ≥32 mg/L, respectively) on the recipient strain. The functionality of blaTMB-1 was evident from the high resistance of OCU_Ac16b to ceftazidime and cefepime (MICs ≥256 and 48 mg/L, respectively), and the high resistance of OCU_Ac16a to cefiderocol (MIC 32 mg/L) could be explained by the additive effect of blaNDM-1 and blaTMB-1.


    </sec>
    <sec>
    <title>Conclusions</title>
    Our data revealed the genomic organization of OCU_Ac16a and demonstrated that all the carbapenemase genes are functional, each contributing to the extremely high broad-spectrum resistance of OCU_Ac16a to β-lactams. As multiple-carbapenemase producers can be serious health threats as drug-resistant pathogens and disseminators of carbapenemase genes, close attention should be paid to their emergence.

    Nutritional status contributes to the regulation of immune responses against pathogens, and malnutrition has been considered as a risk factor for tuberculosis (TB). Mycobacterium tuberculosis (Mtb), the causative agent of TB, can modulate host lipid metabolism and induce lipid accumulation in macrophages, where the bacilli adopt a dormant phenotype. In addition, serum lipid components play dual roles in the regulation of and protection from Mtb infection. We analyzed the relationship between nutritional status and the humoral immune response in TB patients. We found that serum HDL levels are positively correlated with the serum IgA specific for Mtb antigens. Analysis of the relationship between serum nutritional parameters and clinical parameters in TB patients showed that serum albumin and CRP levels were negatively correlated before treatment. We also observed reduced serum LDL levels in TB patients following treatment. These findings may provide insight into the role of serum lipids in host immune responses against Mtb infection. Furthermore, improving the nutritional status may enhance vaccination efficacy.

    <p>The genus <i>Acinetobacter</i> comprises many species that can cause infectious diseases. Despite their importance as nosocomial pathogens, the clinical distributions of individual species or clones are not well understood. In this study, we aimed to characterize 13 <i>Acinetobacter</i> strains isolated from blood cultures from Osaka City University Hospital. We conducted whole-genome sequencing to reveal their genetic background. We also performed PCR-based open reading frame typing (POT) and compared the results with those of multilocus sequence typing (MLST) to confirm its reliability as a genotyping method. Although biochemical analysis suggested that most isolates were <i>A. baumannii</i>, genomic analysis revealed that the collection of <i>Acinetobacter</i> isolates comprised six different species, with non-<i>baumannii Acinetobacter</i> species representing the majority. All strains possessed an inherent ADC-type β-lactamase gene, whereas the distribution of OXA-type enzymes was limited to <i>A. baumannii, A. pittii</i>, and <i>A. colistiniresistens</i>. While MLST properly discriminated four <i>A. baumannii</i> strains as different clones, POT failed to distinguish three of the four <i>A. baumannii</i> strains from each other, highlighting a potential pitfall that may be encountered when applying POT to non-epidemiological <i>A. baumannii</i> strains.</p>

    This study aimed to assess the prognostic factors of patients with bacteremia due to extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) as well as the antimicrobial susceptibility, particularly to piperacillin/tazobactam (PTZ), among ESBL-PE strains. The medical records of 65 patients with ESBL-PE bacteremia divided into the survivor group (n = 52) and nonsurvivor group (n = 13) were retrospectively reviewed. The male-to-female ratio, age, underlying disease, leukocyte count, C-reactive protein level, and treatment did not differ between the 2 groups. Multivariate analysis showed that the independent predictors associated with hospital mortality of ESBL-PE bacteremia were sepsis (P = 0.047) and febrile neutropenia (P = 0.008); thus, early assessment of these conditions is important. Further, the minimum inhibitory concentration values of ESBL-PE isolates in nonsurvivors tended to be higher than those in survivors. PTZ should be used with caution in cases of ESBL-PE strains with low susceptibility to the drug.
