Abstract

Six strains of a hitherto undescribed gram-positive, catalase-negative, facultatively anaerobic coccus isolated from human sources were characterized by phenotypic and molecular taxonomic methods. Comparative 16S rRNA gene sequencing studies demonstrated that the unknown strains were genealogically identical and constitute a new subline within the genus Gemella. The unknown bacterium was readily distinguished from Gemella haemolysans, Gemella bergeriae, and Gemella morbillorum by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Gemella sanguinis sp. nov. The type strain is CCUG 37820(T).

摘要

从人类样本中分离出的6株迄今未描述过的革兰氏阳性、过氧化氢酶阴性、兼性厌氧球菌,通过表型和分子分类学方法进行了鉴定。比较16S rRNA基因测序研究表明,这些未知菌株在系统发育上相同,构成了孪生球菌属内的一个新亚系。通过生化试验和全细胞蛋白电泳分析,该未知细菌很容易与溶血孪生球菌、伯氏孪生球菌和麻疹孪生球菌区分开来。基于系统发育和表型证据,建议将该未知细菌分类为血孪生球菌新种。模式菌株为CCUG 37820(T)。
