DESCRIPTION OF GEMELLA-SANGUINIS SP. NOV., ISOLATED FROM HUMAN CLINICAL SPECIMENS

Six strains of a hitherto undescribed gram-positive, catalase-negative , facultatively anaerobic coccus isolated from human sources were char acterized by phenotypic and molecular taxonomic methods. Comparative 1 6S 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 Ge mella haemolysans, Gemella bergeriae, and Gemella morbillorum by bioch emical tests and electrophoretic analysis of whole-cell proteins. Base d on phylogenetic and phenotypic evidence, it is proposed that the unk nown bacterium he classified as Gemella sanguinis so. nor. The type st rain is CCUG 37820(T).
