RESUMO
BACKGROUND: Intrauterine infection is a recognized cause of adverse pregnancy outcome, but the source of infection is often undetermined. We report a case of stillbirth caused by Fusobacterium nucleatum that originated in the mother's mouth. CASE: A woman with pregnancy-associated gingivitis experienced an upper respiratory tract infection at term, followed by stillbirth a few days later. F. nucleatum was isolated from the placenta and the fetus. Examination of different microbial floras from the mother identified the same clone in her subgingival plaque but not in the supragingival plaque, vagina, or rectum. CONCLUSION: F. nucleatum may have translocated from the mother's mouth to the uterus when the immune system was weakened during the respiratory infection. This case sheds light on patient management for those with pregnancy-associated gingivitis.

One case of primary Desulfovibrio desulfuricans bacteremia in an immunocompetent man is presented, and 15 other reported cases are reviewed. While most isolates have not been identified to the species level, Desulfovibrio fairfieldensis and D. desulfuricans have been associated with incidents of bacteremia and D. vulgaris has been associated with intra-abdominal infections. In vitro studies suggest that empirical therapy with either imipenem or metronidazole should be considered.
