Phylogenetic tree showing the relationship based on the analysis of a 1537-nucleotide region of 16S rRNA genes of vaginal Lactobacillus johnsonii from Chinese rhesus macaques to some representative human vaginal Lactobacillus species. The tree was constructed using the Clustalw program. Ljo_135-1 is a human vaginal isolate of L. johnsonii.
