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

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 C-15: 0. The type strain of B. massiliensis sp. nov. is B84634(T) (= CIP 107942(T) = CCUG 48901(T)).
