Demonstration of vaginal colonization with GusA-expressing Lactobacillus jensenii following oral delivery in rhesus macaques.


ABSTRACT: The vaginal microbiome, which harbors beneficial Lactobacillus strains, is believed to be a major host defense mechanism for preventing infections of the urogenital tract. It has been suggested that the gastrointestinal tract serves as a reservoir for lactobacilli that colonize the vagina. Using rhesus macaques, we examined whether oral delivery of human vaginal Lactobacillus jensenii 1153-1646, a GusA-producing strain, would result in colonization of the rectum and the vagina. Lactobacilli were identified from the vagina tracts of three macaques on the basis of ?-glucuronidase enzyme production, 16S rRNA gene sequence and DNA homology using a repetitive sequence-based polymerase chain reaction.
