Abstract

This work has aimed to evaluate the influence of the L. acidophilus and Candida albicans co-aggregation on the adhesion capacity this microorganisms in the human ephitelial vaginal cells (HEVC). One vaginal isolated of C. albicans and one ATCC strain of L. acidophilus was used. A suspension of the isolated and co-aggregated microorganisms was incubated with HVEC obtained from a healthy donor. After one hour, smears were made with crystal violet and Papanicolaou, and the number of yeasts adhered to HVEC was evaluated (300 superficial-SC and 300 intermediate cells-IC). Scanning electron microscopy (SEM) was made in all situations of the assays. Yeasts and lactobacilli adhered strongly to the HEVC, both SC and IC. The co-aggregation there was an increase in the adhesion capacity of the yeasts (p < 0.001) and a diminished adhesion of the lactobacilli (p < 0.001) in SC and IC. The adhesion of isolated and co-aggregated microorganisms was not significantly different between SC and IC (p > 0.05). Supposing that of these findings correlated with the conditions in vivo, the use of probiotics based on L. acidophilus or its presence in the vaginal microbiota would not protect against the adhesion of C. albicans to the HVEC and possible consequent vulvovaginal candidiasis.
