Cultivation-independent analysis of 16S rRNA gene sequences in vaginal samples revealed two previously unrecognized, uncultivated Megasphaera-like phylotypes. Phylogenetic analysis and environmental distribution suggest that these Megasphaera types may be unique to the vaginal environment. Quantitative PCR suggests that both phylotypes are present in higher concentrations in women with bacterial vaginosis.
