The normal microbial flora of the baboon vagina

The microbial flora of the upper vagina and cervix was examined in 38 adult baboons at various stages of the menstrual cycle. The mean number of different species isolated from each baboon was 9.5, with species of Bacteroides, Corynebacterium and group D streptococci predominating. Lactobacilli and mycoplasmas were found in 47.4 and 44.7% of the animals, respectively. No ureaplasms were isolated. Cyclical variations in the microbial flora were minimal.
