Vaginal Microbiota Molecular Profiling in Women with Bacterial Vaginosis: A Novel Diagnostic Tool.

Bacterial vaginosis (BV) is a most common microbiological syndrome. Multiplex next-generation sequencing (NGS) or molecular tests allow a complete and accurate vaginal microbiota profiling in order to determine the primary causative agent. Due to the high costs and limited availability of NGS, the multiplex real-time PCR draws more attention.

Local Immune Biomarker Expression Depending on the Uterine Microbiota in Patients with Idiopathic Infertility.

The endometrium has traditionally been considered sterile. Nowadays, active studies are performed on the female upper genital tract microbiota. Bacteria and/or viruses colonizing the endometrium are known to alter its functional properties, including receptivity and embryo implantation.

Performance of the first commercial dual resistance assay, AmpliSens -ML/FQ-Resist-FL, for detection of potential macrolide and quinolone resistance-associated mutations and prevalence of resistance mutations in St. Petersburg, Russia.

Objectives: Antimicrobial resistance in (MG) is a poorly surveyed and controlled global health concern. We evaluated the first commercial dual resistance assay, AmpliSens -ML/FQ-Resist-FL assay, for detection of potential macrolide and quinolone resistance-associated mutations (MRAMs and QRAMs, respectively) and estimated the prevalence of these mutations in MG in St. Petersburg, Russia.

Antimicrobial resistance profiles and genes in uropathogenic Enterobacteriaceae in reproductive-age women in St. Petersburg, Russia: implication for treatment of pyelonephritis in pregnancy.

Background: Urinary tract infections (UTIs) are common in women, and during pregnancy can cause significant morbidity. Growing and greatly varying antimicrobial resistance (AMR) of Enterobacteriaceae, responsible for most UTIs, necessitates regular local AMR surveillance. In obstetric population, where beta-lactams are the mainstay for treatment of severe UTIs, particular focus should be placed on beta-lactam resistance.

Differential Expression of Local Immune Response Genes in the Vagina: Implication for the Diagnosis of Vaginal Infections.

Transcription profiles of genes of local immune response were determined in the vagina of women with bacterial vaginosis, aerobic vaginitis, and vulvovaginal candidosis for detection of the most specific immune markers for these vaginal infections. Laboratory diagnosis of the vaginal infections was performed microscopically; the inflammatory reaction in the vagina (leukorrhea) was defined as the presence of >10 white blood cells per field of view. Transcription profiles of IL1b, IL10, IL18, TNFα, TLR4, GATA3, and CD68 were determined using reverse-transcription quantitative real-time PCR.
