Characterization of putative sialidase genes in Gardnerella vaginalis
Gardnerella vaginalis is a hallmark organism in the dysbiosis bacterial vaginosis (BV) in reproductive age women although its role in this condition is not currently understood. Diversity within G. vaginalis in terms of virulence factors such as sialidase activity, may explain why it is also …

Induction of metronidazole and clindamycin resistance in gardnerella vaginalis
… opportunistic pathogenic bacteria particularly Gardnerella vaginalis. G. vaginalis is a gram-variable pleomorphic bacterium which under normal conditions is considered to exhibit low virulence. G. vaginalis is the most common bacterial species isolated from patients with BV, and isolated in over …

Characterization of adherence, cytotoxicity and biofilm formation by Gardnerella vaginalis
… BV cases, the predominant bacterial species is Gardnerella vaginalis. It has been demonstrated that G. vaginalis forms an adherent biofilm on the vaginal epithelium of women with BV. Furthemore, evidence suggests that the high rate of recurrence associated with BV is related to incomplete …

Characterizing the genotypic and phenotypic diversity of Gardnerella vaginalis from vaginal clinical samples
… is not well characterized, it is understood that Gardnerella vaginalis plays a critical role in BV by initiating the formation of the polymicrobial biofilm that characterizes BV and by degrading protective vaginal mucus through the release of sialidase. Recent evidence suggests that the G. …

Screening for novel compounds produced by Actinobacteria and Gardnerella vaginalis that impact HIV-1 infection
… and the BV-associated bacterium (BVAB) Gardnerella vaginalis (GV) could impact HIV infection. NPs from 23 actinobacteria strains were extracted and tested on pseudovirus (PSV) infection. Ten strains showed a range of anti-viral activity from 50 µg/mL to 25 µg/mL, and the identity of the …

Μικροβίωμα και υπογονιμότητα
… μικροοργανισμών (π.χ., Chlamydia trachomatis, Gardnerella vaginalis), συνδέεται άμεσα με φλεγμονές, χαμηλότερα ποσοστά επιτυχίας στην εξωσωματική γονιμοποίηση (IVF) και αυξημένο κίνδυνο αποτυχίας εμφύτευσης. Επιπλέον, τα δεδομένα δείχνουν ότι το προφίλ του κολπικού μικροβιώματος μπορεί να …

The regulation of bacterial virulence by mucin glycans
… epithelial cell killing by the vaginal pathogen Gardnerella vaginalis. Together, these results present a roadmap for the development of mucin-inspired antivirulence materials for various niches. With the rise of clinical antimicrobial resistance, these materials, which treat infections by …

Baboon vaginal microbiota: an overlooked aspect of primate physiology
… in the human vagina, with Actinobacteria (Gardnerella vaginalis) and Proteobacteria present in lower numbers. By contrast, Papio baboons harbored species not only of Firmicutes but also of Fusobacteria, Bacteroidetes and Spirochaetes phyla that are not normally abundant in humans. Moreover, …

Επιδημιολογική διερεύνηση λοίμωξης γεννητικού συστήματος από Chlamydia Trachomatis στον Ελλαδικό χώρο την τελευταία τριετία
… μαζί με τα C. trachomatis, το πιο συχνό ήταν η Gardnerella Vaginalis και σε ένα ποσοστό του 43% δεν είχαν ταυτόχρονη λοίμωξη από άλλο ΣΜΝ. Η έγκαιρη διάγνωση, η κατάλληλη θεραπεία και η σωστή ενημέρωση του πληθυσμού είναι καθοριστικής σημασίας για τον περιορισμό εξάπλωσης της λοίμωξης. Η …

Gene expression patterns of the female genital tract and immunomodulation by Lactobacillus species
… L. jensenii, L. mucosae, L. crispatus and L. vaginalis species were included in this study. The effects of these lactobacilli on cytokine production by vaginal epithelial (VK2) cells stimulated with Gardnerella vaginalis (ATCC 14018) were tested in vitro, RNA was extracted and used for …

Tiny Can Be Big: The Contribution of Microbial Extracellular Vesicles to Host-Pathogen Interactions
… the infection caused by the parasite Trichomonas vaginalis. This flagellated protozoan is a causative agent of trichomoniasis, one of the world’s most common non-viral sexually transmitted infections. The co-existence of these pro- and eukaryotic microorganisms (i.e. bacteria and protozoan) in the …

Characterisation of the HIV inhibitory activity of vaginal lactobacilli isolates from young South African women at high risk of HIV acquisition
… L. plantarum, L. ruminis, L. salivarius and L. vaginalis, were isolated from young South African women who participated in the Women's Initiative in Sexual Health (WISH) study. The production of pro-inflammatory cytokines (IL-6, IL-1α, IL-1β), chemokines (IL-8, IP-10, MIP-3α, MIP-1α, MIP-1β) and …

Diversity of vaginal microbiota associated with bacterial vaginosis and the impact on pregnancy outcomes in HIV-infected and uninfected women.
… crispatus dominant and 145/356 (41%) CST3 - Gardnerella vaginalis dominant. There was a high prevalence of dysbiotic vaginal communities and L. iners was the predominant taxa found in > 90% of the women. When exploring whether the vaginal microbiota is associated with pregnancy outcomes, L. …
