Lactobacillus species isolated from posterior fornix of the vagina of 410 Korean women, who visited several local clinics and the Family Health Clinic of the Institute of Reproductive Medicine and Population, Seoul National University in Seoul were identified by their physiological and biochemical characteristics. And the results were as follows.
1) Of the 410 women 297 (72.4%) gave the positive culture for Lactobacillus.
2) Isolated 200 strains were differentiated into following species. L. salivarius (43 strains, 18.7%) and L. leichmannii (42,18.3%) were the most common species followed by L. plantarium (34, 14.8%) L.brevis (22, 9.6%), L. fermenti (19.8.3%), L. cellobiosus(15. 6.5%), L. acidophilus (14, 6.1%). L. delbrueckii (10. 4.3%) and L. casei (1, 0.4%) and there were 30 strains (13,%) which could not have been identified by the methods employed in this study.
3) Age seems to have no influence on the distribution of Lactobacillus species in vagina and it seems like that the overall distribution of Lactobacillus species in vagina does not change during the active reproductive period of women.
