The presence of bifidobacteria and representatives of the new genus Pseudoscardovia within the family Bifidobacteriaceae in the digestive tract of wild pigs was reported recently. Results based on comparative 16S rRNA gene sequence analysis of a new fructose-6-phosphate phosphoketolase-positive bacterial isolate, strain DPVI-TET3T, originating from the small intestine of a wild pig revealed a relationship to Pseudoscardovia suis DPTE4T (96.8 % sequence similarity). Phylogenetic and comparative analyses based on 16S rRNA, hsp60, xfp, fusA, tuf and rpoC partial gene sequences confirmed the relationship of the novel bacterial strain to P. suis DPTE4T in comparison with other bifidobacterial species occurring in the digestive tract of domestic and wild pigs. Differences in utilization of various substrates, production of enzymes, cell morphology, peptidoglycan structure and profiles of cellular fatty acids and polar lipids between strain DPVI-TET3T and P. suis DPTE4T allow the establishment of a novel species, for which the name Pseudoscardovia radai sp. nov. is proposed. The type strain is strain DPVI-TET3T ( = CCM 7943T = DSM 24742T).
