Bacteroides massiliensis sp. nov., isolated from blood culture of a newborn

Abstract
Gram-negative anaerobic rods were isolated from blood culture of a healthy baby born at term. Based on phylogenetic analysis and specific phenotypic characteristics, this strain was included within the Bacteroides cluster. The novel bile-resistant anaerobic species was designated Bacteroides massiliensis and it has 92·8 % 16S rRNA similarity to Bacteroides vulgatus and a DNA G+C content of 49 mol%. The major cellular fatty acid is anteiso-branched C15 : 0. The type strain of B. massiliensis sp. nov. is B84634T (=CIP 107942T=CCUG 48901T).
