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.
我们报告了一例60岁男性感染脱硫脱硫弧菌败血症的病例。在我们的病例中，厌氧血培养瓶在培养五天后呈阳性。革兰氏染色显示存在轻度弯曲的革兰氏阴性杆菌。怀疑是弯曲杆菌和幽门螺杆菌，我们增加了微需氧培养，同时向医生初步报告为弯曲杆菌。由于微需氧培养证明不存在微需氧菌，我们随后添加了布鲁氏菌HK（RS）琼脂进行厌氧培养。第三天我们发现了小菌落，然后开始厌氧培养，最终鉴定为脱硫脱硫弧菌。我们认为这是日本首例从血液中培养出脱硫脱硫弧菌的报告。如果革兰氏染色显示存在螺旋菌，建议考虑脱硫弧菌并密切观察。
