Abstract

We identified Lactobacillus isolates from Japanese women and newborn infants by a DNA-DNA hybridization method. The predominating lactobacilli were Lactobacillus crispatus and Lactobacillus gasseri in the women's vaginas and the newborns' intestines and L. gasseri and Lactobacillus fermentum in the women's intestines. All L. crispatus strains were exclusively strong H2O2 producers.
