To investigate the exact isolation frequency of 16S rRNA methylase-producing, gram-negative pathogenic bacteria, we tested 87,626 clinical isolates from 169 hospitals. Twenty-six strains from 16 hospitals harbored 16S rRNA methylase genes, which suggests sparse but diffuse spread of pan-aminoglycoside-resistant microbes in Japan.

The presence of high-risk human papillomavirus (HR-HPV) contributes to the development of cervical lesions and cervical cancer. Recent studies suggest that an imbalance in the cervicovaginal microbiota might be a factor in the persistence of HR-HPV infections. In this study, we collected 156 cervicovaginal fluid (CVF) of women with HR-HPV infection, which were divided into three groups (negative for intraepithelial lesions = 78, low/high-grade squamous intraepithelial lesions = 52/26).

Background: Jianwei Xiaoshi oral liquid (JWXS), a classical traditional prescription comprising various edible medicinal plants, has demonstrated significant efficacy in treating paediatric indigestion. It originates from Jianpi Pill, which is developed in the Ming Dynasty and nourishes the spleen and regulates gastrointestinal function. However, the specific molecular mechanisms involved remain unclear.

Microbiota analysis of perimenopausal women experiencing recurrent vaginitis in conjunction with urinary tract infection.

Background: Recurrent vaginitis in conjunction with urinary tract infection (RV/UTI) in perimenopausal women is a common clinical condition that impacts both doctors and patients. Its pathogenesis is not completely known, but the urogenital microbiota is thought to be involved. We compared the urogenital and gut microbiotas of perimenopausal women experiencing RV/UTI with those of age-matched controls to provide a new microbiological perspective and scheme for solving clinical problems.

This study aimed to achieve two main objectives: first, to determine whether the virulence factors of symbiotic bacteria of entomopathogenic nematodes (EPNs) against insect hosts are cell-associated or secreted, and to shed light on the underlying mechanisms of pathogenicity; and second, to identify and evaluate the standalone pathogenicity of symbiotic bacteria associated with entomopathogenic nematodes against Tenebrio molitor. Three bacterial species, Xenorhabdus nematophila (A41, SC, A18 and SF), Photorhabdus kayaii, and P. thracensis, were isolated and characterized via phylogenetic analysis of 16S-rRNA and gyrB genes.
