A fastidious, slowly growing, spiral gram-negative bacterium was isolated from the liver abscess of an 82-year-old man with a 3-week history of febrile illness. The organism was an obligate anaerobe that grew at 37 and 42 degrees C but not at 25 degrees C. Its vibrioid or spiral morphology on Gram staining, rapid progressive motility, electron micrograph features, and biochemical tests were all consistent with the organism belonging to the genus Desulfovibrio. 16S rRNA gene sequencing of this organism demonstrated a 97% similarity to Desulfovibrio desulfuricans with 45 nucleotide differences, suggesting that it is a new species of Desulfovibrio.
从一名82岁男性的肝脓肿中分离出一种苛求、生长缓慢、革兰氏阴性螺旋菌,该患者有3周的发热病史。该菌为专性厌氧菌,在37℃和42℃生长,但在25℃不生长。其革兰氏染色的弧状或螺旋形态、快速进行性运动、电子显微镜特征及生化试验均与脱硫弧菌属一致。该菌的16S rRNA基因测序显示与脱硫脱硫弧菌有97%的相似性,有45个核苷酸差异,提示它是脱硫弧菌属的一个新种。
