Dolosicoccus paucivorans gen. nov., sp. nov., isolated from human blood.

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.
