The authors studied on the microbial flora of the lower genital tract and its influential factors. The adult female genital tract has a very complex microbial flora, constantly changing under the condition of the menstrual cycle. The presence of glycogen in the vaginal mucosa was controlled by the secretion of estrogen and progesteron. A large population of Lactobacilli helps to maintain the pH of the vagina and external cervical ostium ranged approximately between 4.4 and 4.6,but E. coli is inhibited from growth at the pH of less than 5. Table 2 shows the distribution of micro-organisms in 238 unselected women, described in the descending order of frequency ; Lactobacilli, Corynebacterium and Staphylococcus epidermidis were present as heavy growth. In our findings vaginal microbial flora was influenced by inflamations, malignant lesions and ages. Ages were the most important factor among them. Although Lactobacillus and Candida albicans were detected more frequently from younger women than from olders, Pseudomonas aeruginosa and Bacillus were frequent among the older than 50 years old. We concluded that the facts above described concerning the flora of the lower genital tract were related strongly to the ovarial function.
