Electronic address:

Article Synopsis
  • The study analyzed the vaginal microbiota of non-pregnant women, pregnant women, and commercial sex workers in Japan, highlighting how these microbiota change due to factors like health and sexual activity.
  • Samples from 54 women were examined, resulting in three distinct microbiota groups, with different dominance of Lactobacillus spp. across groups, particularly showing a strong presence in pregnant women.
  • Findings indicated that the presence and diversity of Lactobacillus spp. were lower in commercial sex workers and suggested that Lactobacillus dominance might affect the risk of preterm birth in women taking ritodrine hydrochloride during pregnancy.

Article Synopsis
  • The study investigates the relationship between Clostridioides difficile ribotypes, restriction endonuclease analysis (REA) types, and toxin gene expression in clinical strains.
  • Researchers analyzed 53 clinical strains, classifying them into 17 ribotypes and six REA types, and measured the expression levels of toxin genes using real-time PCR methods.
  • Findings revealed no link between ribotype and toxin gene expression, indicating that the production of binary toxin was unrelated to the levels of tcdA and tcdB.

Article Synopsis
  • The study investigates the relationship between the exoU + genotype in multidrug-resistant Pseudomonas aeruginosa and its resistance genes.
  • The exoU + genotype is commonly found in strains resistant to carbapenems and fluoroquinolones, with overexpression of certain resistance genes like mexY and ampC linked to this virulence factor.
  • Understanding these relationships may aid in better treatment strategies for infections caused by these hard-to-treat bacteria.

Candida species bloodstream infection, or candidemia, remains an important health issue with high morbidity and mortality. Bloodstream infections caused by Candida species are often associated with the ability of Candida to form biofilms on medical devices, such as central venous catheters. Non-albicans Candida species have been increasing gradually in clinical settings.

The introduction of the 7-valent pneumococcal conjugate vaccine (PCV7) in February 2010 markedly reduced the burden of invasive pneumococcal disease and changed serotype distribution in Japan. In November 2013, PCV7 was replaced by the 13-valent pneumococcal conjugate vaccine (PCV13). We investigated the serotype distribution and susceptibility trends of non-invasive Streptococcus pneumoniae isolates collected from adult patients.

 Carbapenem-resistant has increased dramatically in the last decade, resulting in infections that are difficult to treat and associated with high mortality rates. To prevent further antibacterial resistance, it is necessary to use carbapenem selectively. A combination of metronidazole with an antimicrobial agent active against aerobes is an alternative effective treatment for patients with complicated intra-abdominal infections (cIAIs).

The presence of anaerobes in the blood stream is known to be associated with a higher rate of mortality. However, few prognostic risk factor analyses examining whether a patient's background characteristics are associated with the prognosis have been reported. We performed a retrospective case-controlled study to assess the prognostic factors associated with death from anaerobic bacteremia.

We characterized 12 clinical isolates of Klebsiella oxytoca with the extended-spectrum β-lactamase (ESBL) phenotype (high minimum inhibitory concentration [MIC] values of ceftriaxone) recovered over 9 months at a university hospital in Japan. To determine the clonality of the isolates, we used pulsed-field gel electrophoresis (PFGE), multi-locus sequence typing (MLST), and PCR analyses to detect blaRBI, which encodes the β-lactamase RbiA, OXY-2-4 with overproduce-type promoter. Moreover, we performed the isoelectric focusing (IEF) of β-lactamases, and the determination of the MICs of β-lactams including piperacillin/tazobactam for 12 clinical isolates and E.

Non-albicans Candida species are being isolated with increasing frequency. In this study, biofilm formation by Candida tropicalis, Candida parapsilosis and Candida glabrata was evaluated and the activities of liposomal amphotericin B (LAB), micafungin (MFG) and fluconazole (FLC) against these biofilms were assessed using a clinically relevant in vitro model system. LAB exhibited strong activities against the three non-albicans Candida species and showed dose-dependent efficacy.

Department of Clinical Infectious Diseases, Aichi Medical University Graduate School of Medicine, Aichi, Japan; Clinical Research, Development Japan, Pfizer Japan Inc., Tokyo, Japan.

Unlabelled: Vulvovaginal candidiasis is the second most common cause of vaginal infections following bacterial vaginosis. For the treatment of vulvovaginal candidiasis, antifungal agents are used either as topical (vaginal tablets and cream) or oral formulations. A single oral 150 mg dose of fluconazole has been recommended as the standard therapy for uncomplicated, acute vulvovaginal candidiasis in global guidelines; however, in Japan oral fluconazole therapy has not been approved.

Department of Clinical Infectious Diseases, Aichi Medical University Graduate School of Medicine, Aichi, Japan; Clinical Research, Development Japan, Pfizer Japan Inc., Tokyo, Japan.

Although metronidazole (MNZ) has been used worldwide for more than 4 decades as a standard therapy for trichomoniasis, anaerobic and amebic infections, resistance to MNZ is still low. MNZ is available as oral, intravenous, and vaginal formulations, but the intravenous formulation of MNZ has not been approved in Japan. We conducted a phase 3 study to evaluate the efficacy and safety of intravenous MNZ combined with ceftriaxone (CTRX) in Japanese subjects with infectious peritonitis, abdominal abscess or pelvic inflammatory diseases (PIDs) to obtain regulatory approval.

Background: The emergence of multi-drug-resistant gram-negative rods (MDR-GNRs) has become a worldwide problem. To limit the emergence of MDR-GNRs, a tertiary care cancer center in Japan implemented a policy that requires the pre-emptive isolation of patients with organisms that have the potential to be MDR-GNRs.

Methods: A retrospective analysis was performed.
