[Anaerobiospirillum succiniciproducens septicemia].

We report the first case of septicemia caused by anaerobic spiral-shaped Gram negative bacilli, Anaerobiospirillum succiniciproducens in Japan. A 71-year-old male who had been suffered from terminal stage of liver cirrhosis and hepatocelluler carcinoma was admitted to our hospital for his symptoms of general malaise and increasing ascites on September 1, 2004. He developed diarrhea seven times a day on the eighth hospital day and had fever of 38.7 degrees C with WBC 12,600/microl and CRP 6.6 mg/dl on the next day. Blood culture grew Gram negative spiral bacilli. We initially could not identify the offending bacterium that resembled to Campyrobacter morphologically using commercially available indentification kits. However, 16SrRNA sequencing test revealed 100% compatibility with Anaerobiospirillum succiniciproducens.
