- Abstract
Two Bifidobacterium strains, i.e., 2176B
T and 2177BT , were isolated from Golden-Headed Lion Tamarin ( Leontopithecus chrysomelas ) and Goeldi's monkey ( Callimico goeldii ). Isolates were shown to be Gram-positive, non-motile, non-sporulating, facultative anaerobic and d-fructose 6-phosphate phosphoketolase-positive. Phylogenetic analyses based on 16S rRNA sequences, multilocus sequences (including hsp 60, rpo B, dna J, dna G and clp C genes) and the core genome revealed that bifidobacterial strains 2176BT and 2177BT exhibit close phylogenetic relatedness to Bifidobacterium felsineum DSM 103139T and Bifidobacterium bifidum LMG 11041T , respectively. Further genotyping based on the genome sequence of the isolated strains combined with phenotypic analyses, clearly show that these strains are distinct from each of the type strains of the so far recognized Bifidobacterium species. Thus, Bifidobacterium cebidarum sp. nov. (2176BT =LMG 31469T =CCUG 73785T ) and Bifidobacterium leontopitheci sp. nov. (2177BT =LMG 31471T =CCUG 73786T are proposed as novel Bifidobacterium species.- Published
