ABSTRACT

Two strains of a hitherto undescribed Gram-positive catalase-negative, facultatively anaerobic coccus isolated from human sources were characterizec by phenotypic and molecular taxonomic methods. Comparative 16S rRNA gene sequencing studies demonstrated the unknown strains were genealogically identical, and constitute a new line close to, but distinct from, the genera Facklamia and Globicatella. The unknown bacterium was readily distinguished from Facklamia species and Globicatella sanguinus by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on phylogenetic and phenotypic evidence it is proposed that the unknown bacterium be classifiec as lgnavigranum ruoffiae gen. nov., sp. nov. The type strain of lgnavigranum ruoffiae is CCUG 37658T.

Key Words: Ignavigranum ruoffiae • taxonomy • phylogeny • 16S rRNA

The GenBank accession number for the 16S rRNA sequence of CCUG 37658Tis Y16426.
