PHENOTYPIC AND PHYLOGENETIC CHARACTERIZATION OF SOME GEMELLA-LIKE ORGANISMS FROM HUMAN INFECTIONS - DESCRIPTION OF DOLOSIGRANULUM PIGRUM GEN-NOV, SP-NOV

A phylogenetic analysis was performed on two previously uncharacterize d Gram-positive, catalase-negative bacteria from clinical sources. 16S rRNA sequencing studies revealed the isolates represent a new line of descent within the lactic acid group of bacteria. On the basis of the phylogenetic findings and phenotypic distinctiveness of the organisms , it is proposed that they be classified in a new genus Dolosigranulum , as Dolosigranulum pigrum sp. nov. The type strain of Dolosigranulum pigrum is NCFB 2975.
