Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 23: Suitability of taxonomic units notified to EFSA until September 2025

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety of microorganisms intentionally added to the food and feed chain.

Type II Restriction-Modification System from Gardnerella vaginalis ATCC 14018

Pathogens, 2020
Intensive horizontal gene transfer may generate diversity and heterogeneity within the genus Gardnerella. Restriction-modification (R-M) systems and CRISPR-Cas are the principal defense tools against foreign DNA in bacteria.

Erucic Acid, Derived by Lactobacillus Crispatus, Induces Ferroptosis in Cervical Cancer Organoids Through the PPAR‐δ Signaling Pathway

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Utilizing PDO, cell lines and cervical cancer xenograft (CDX) models, the study demonstrate both in vitro and in vivo that the metabolite of L. crispatus, erucic acid, can modulate the proliferation, migration and invasion of cervical cancer by activating the PPAR‐δ pathway.

Antimicrobial susceptibilities of Gardnerella vaginalis

Antimicrobial Agents and Chemotherapy, 1993
The in vitro susceptibilities of 93 clinical isolates of Gardnerella vaginalis to 25 antimicrobial agents were determined by the agar dilution method. All isolates were susceptible to penicillin, ampicillin, erythromycin, clindamycin, chloramphenicol, and trimethoprim.

Anaerobes and bacterial vaginosis in pregnancy: virulence factors contributing to vaginal colonisation [PDF]

, 2014
The aetiology and pathogenesis of bacterial vaginosis (BV) is unclear but it appears to be associated with factors that disrupt the normal acidity of the vagina thus altering the equilibrium between the normal vaginal microbiota.

Evaluation of Metronidazole Resistance of Vaginal Swab Isolates from South African Women Treated for Bacterial Vaginosis

Antibiotics
Background/Objectives: The high recurrence rate of bacterial vaginosis (BV) after antibiotic treatment is at least partially attributed to resistant bacteria.

Growth Forms of Gardnerella spp. and Lactobacillus spp. on Vaginal Cells

Frontiers in Cellular and Infection Microbiology, 2020
Bacterial vaginosis (BV) is a common vaginal condition in women of reproductive age. During BV development, BV-associated bacteria may form a polymicrobial biofilm, which predispose women to recurrent BV.

Distinct cervical tissue-adherent and luminal microbiome communities correlate with mucosal host gene expression and protein levels in Kenyan sex workers

Microbiome, 2023
Background The majority of studies characterizing female genital tract microbiota have focused on luminal organisms, while the presence and impact of tissue-adherent ectocervical microbiota remain incompletely understood.
