Vaginal and uterine bacterial flora at different stages of the estrus cycle in bitches
The aim of this study was to compare the bacterial flora of canine vagina and uterus and assess its composition during the estrus cycle. From 28 healthy bitches, vaginal smears and samples of uterine secretion by means of endoscopy were collected during the estrus cycle (anestrus, proestrus, estrus, metestrus) for bacteriological investigation. Similar bacterial flora were present in the vagina and uterus of bitches. Lactobacillus sp., a-hemolytic streptococci, Staphylococcus intermedius, Pasteurella multocida and E. coli were most frequently found. The average number of isolates was 2.2 per vaginal sample and 1.4 per uterine sample, the uterine samples also showed a lower bacterial count. The composition of vaginal and uterine bacterial flora and amounts of bacteria varied during the estrus cycle. The highest bacterial count occurred during proestrus.
