Changes in Normal Vaginal Flora of African Green Monkeys (Cercopithecus aethiops) During the Menstrual Cycle

摘要

Changes in normal vaginal flora of African green monkeys associated with the estrous cycles were examined by the swab method. Bacteroidaceae, corynebacteria, and streptococci were predominant throughout the whole estrous cycle, although individual differences were great. It was also clear that all bacterial species tended to decrease in the menstrual phase. Lactobacilli, the most predominant bacteria in the normal vagina of humans, were detected only in very low numbers in the African green monkey, suggesting that the normal vagina of the African green monkey has a different ecosystem from that of normal human vaginal flora.
