RESUMO
We report a case of Desulfovibrio desulfuricans bacteremia in a 60-year-old-man. In our case, anaerobic blood culture bottle turned out positive after five days' incubation. Gram stain showed the presence of slightly-curved Gram negative rod. Suspecting Campylobacter and Helicobacter, we added microaerobic culture while tentatively reporting Campylobacter to the physician. We then added anaerobic culturing with Brucella HK (RS) Agar because microaerobic culture proved the absence of microaerophile. We found small colonies on the third day, then we started anaerobic culture and eventually identified Desulfovibrio desulfuricans. We believe this is the first report of Desulfovibrio desulfuricans cultured from blood in Japan. In case Gram stain shows the presence of spiral bacterium, it is recommended to observe closely considering Desulfovibrio.
