Characterization of culturable vaginal Lactobacillus species among women with and without bacterial vaginosis from the United States and India: a cross-sectional study. Lactobacillus species play an integral part in the health of the vaginal microbiota. We compared vaginal Lactobacillus species in women from India and the USA with and without bacterial vaginosis (BV). Between July 2009 and November 2010, a cross-sectional study was conducted among 40 women attending a women's health clinic in Mysore, India, and a sexually transmitted diseases clinic in San Francisco, USA. Women were diagnosed with BV using Amsel's criteria and the Nugent score. Lactobacillus 16S rDNA was sequenced to speciate the cultured isolates. Ten Indian and 10 US women without BV were compared with an equal number of women with BV.
