Abstract

Cervicovaginal (CV) microbiota is critical for the well-being of host. We investigated the relationship between the ratio of Lactobacilli (LB) and cocci/coccobacilli (C/CB)-type microbial cells with biofilm formation of CV mixed cultures of women with no inflammation/infection or any epithelial abnormalities in Pap-stained smears Group 1 (G1) corresponds to the flora with LB-type cells alone, whereas G2 corresponds to the LB-dominated flora. G3 contains balanced LB and C/CB cells and G4 is dominated with C/CB. G5 corresponds to a flora with C/CB-type cells alone. Biofilm formation of CV mixed cultures was assessed by crystal violet binding assay and optical density (OD)≥0.8 were defined as biofilm producers. G1 and G3 exist in higher frequencies compared to the other smear groups. However, although the frequency of G5 dominated with C/CB-type cells were the lowest (4%); biofilm formation in that group was observed in the highest frequency (42.9%). The least biofilm formation frequency was observed in G3 smears with balanced flora (1%). Biofilm formation in healthy CV flora increases when there becomes an imbalance between LB and C/CB-type cells and an increase in C/CB-type cells. Our approach may enable early detection of vaginal dysbiosis in healthy flora prone to biofilm-associated CV infections such as bacterial vaginosis (BV).

期刊介绍: Biotechnic & Histochemistry (formerly Stain technology) is the official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926. Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well. Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
