Abstract

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.

摘要

对从人血液中分离出的一株迄今未描述的革兰氏阳性、过氧化氢酶阴性、成链状球菌进行了表型和系统发育研究。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谱系，与法克勒菌属和球链菌属相近，但又有所不同。通过生化试验和全细胞蛋白的电泳分析，该未知细菌很容易与目前公认的法克勒菌属物种和血球链菌区分开来。基于系统发育和表型证据，建议将该未知细菌分类为少食狡诈球菌属，新属，新种。少食狡诈球菌的模式菌株为CCUG 39307T。
