First isolation of Desulfovibrio from the human vaginal flora.
Four Desulfovibrio species, including 2 subtypes of 1 species, namely, Desulfovibrio piger, Desulfovibrio desulfuricans MB subtype and Essex 6 subtype, Desulfovibrio fairfieldensis, and Desulfovibrio vulgaris, have been isolated from the human oral and intestinal flora, but not previously from the vaginal flora. They are opportunistic pathogens and have been considered as possible environmental and etiologic agents involved in ulcerative colitis and chronic periodontitis. We isolated Desulfovibrio intestinalis from vaginal specimens of four Japanese women; a species which has not been previously isolated from humans. The vaginal isolates were highly resistant to cefoxitin, piperacillin, and piperacillin-tazobactam but were susceptible to the other antimicrobial agents tested. Our findings suggested that vaginal Desulfovibrio species may be involved in gynecological or obstetric pathology, and provides additional information of the medical relevance on human Desulfovibrio species.
