Strain FH26001/95 (ATCC 700045) was previously isolated from a pyogenic liver abscess from a human. Comparative 16S rRNA gene sequence analysis showed that this strain is related to members of the delta subgroup of the proteobacteria, within a cluster of sulfate-reducing bacteria (Desulfovibrio spp.) and non-sulfate-reducing bacteria (Bilophila wadsworthia and Lawsonia spp.). The phenotype of strain FH26001/95 was found to be typical of members of the genus Desulfovibrio. Growth and substrate transformations were possible at oxygen concentrations of 2 to 5% (vol/vol) but not at oxygen concentrations of 21% (vol/vol) in air. Its isolation from an infection in a human suggests that some members of the genus Desulfovibrio can be considered opportunistic pathogens.
菌株FH26001/95(ATCC 700045)先前从一名人类的化脓性肝脓肿中分离得到。16S rRNA基因序列比较分析表明,该菌株与变形菌门δ亚群的成员相关,属于硫酸盐还原菌(脱硫弧菌属)和非硫酸盐还原菌(沃兹沃思嗜胆菌和劳森菌属)的一个簇。发现菌株FH26001/95的表型是脱硫弧菌属成员的典型表型。在氧气浓度为2%至5%(体积/体积)时可生长并发生底物转化,但在空气中氧气浓度为21%(体积/体积)时则不能。它从人类感染中分离出来表明,脱硫弧菌属的一些成员可被视为机会致病菌。
