In vitro adherence of Lactobacillus species to vaginal epithelial cells. 1985

J R Wood, and R L Sweet, and A Catena, and W K Hadley, and M Robbie

Because of the reported use of yogurt douches for the treatment of vaginitis, the adherence of Lactobacillus species to normal human vaginal epithelial cells was tested by in vitro methods. L. acidophilus and L. bulgaricus isolated from three commercial yogurts were compared to L. acidophilus, L. fermentum, L. cellobiosus, and L. casei isolated from clinical specimens and from American Type Culture Collection cultures. L. acidophilus isolated from Lactinex tablets was also tested. No significant difference was found among the 19 clinical isolates, the American Type Culture Collection cultures, and the Lactinex isolate, but all showed significantly higher (p less than 0.01) adherence than any Lactobacillus isolated from yogurt. The presence of Gardnerella vaginalis, which adheres strongly to vaginal epithelial cells, was found to interfere with the adherence of lactobacilli from all sources studied.

UI MeSH Term Description Entries
D007778 Lactobacillus A genus of gram-positive, microaerophilic, rod-shaped bacteria occurring widely in nature. Its species are also part of the many normal flora of the mouth, intestinal tract, and vagina of many mammals, including humans. Lactobacillus species are homofermentative and ferment a broad spectrum of carbohydrates often host-adapted but do not ferment PENTOSES. Most members were previously assigned to the Lactobacillus delbrueckii group. Pathogenicity from this genus is rare.
D007779 Lactobacillus acidophilus A species of gram-positive, rod-shaped bacteria isolated from the intestinal tract of humans and animals, the human mouth, and vagina. This organism produces the fermented product, acidophilus milk. Lactobacillus amylovorus
