摘要
表型和系统发育研究进行了迄今未描述的革兰氏阳性，过氧化氢酶阴性，从人血液中分离的链状球菌。比较16S rRNA基因测序研究表明，该未知生物构成了一个新的系统发育系，与Facklamia和Globicatella接近但不同。通过生化试验和全细胞蛋白电泳分析，很容易将该未知细菌与目前已知的法克兰菌和血球菌区分开来。根据系统发育和表型证据，提出该未知细菌可归类为贫微球球菌(Dolosicoccus paucivorans gen. nov.， sp. nov.)，贫微球球菌的型菌株为CCUG 39307T。
Dolosicoccus paucivorans gen. nov., sp. nov., isolated from human blood.
Phenotypic and phylogenetic studies were performed on a hitherto undescribed Gram-positive, catalase-negative, chain-forming coccus isolated from human blood. Comparative 16S rRNA gene sequencing studies demonstrated that the unknown organism constitutes a new phylogenetic line, close to, but distinct from, Facklamia and Globicatella. The unknown bacterium was readily distinguished from currently recognized Facklamia species and Globicatella sanguinis by biochemical tests and electrophoretic analysis of whole-cell proteins. On the basis of phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Dolosicoccus paucivorans gen. nov., sp. nov. The type strain of Dolosicoccus paucivorans is CCUG 39307T.
