Butyricicoccus porcorum is a Gram-positive, anaerobic, butyrate-producing bacterium belonging to the genus Butyricicoccus. It was first isolated from the swine gastrointestinal tract and officially described as a novel species in 2018.[1]
Cells of B. porcorum are non-motile, coccoid-shaped, and obligate anaerobes. The organism exhibits mesophilic growth conditions (optimal at 37°C) and forms white to off-white colonies approximately 2 mm in diameter after two days of growth. It ferments mono- and disaccharides predominantly into butyrate.[1]
Phylogeny
Phylogenetic analyses based on 16S rRNA gene sequences indicate B. porcorum shares closest similarity (~93.5%) with Butyricicoccus pullicaecorum.[1]
Isolation and distribution
Initially isolated from the distal ileum of swine in Iowa, USA, the type strain is BB10T (=ATCC TSD-102T, DSM 104997T).[1] More recently, a strain of B. porcorum (Bp 531D) was isolated from human gut microbiota, suggesting broader host distribution.[2]
B. porcorum has also been found to be significantly more abundant in the gastrointestinal microbiota of post-weaned pigs compared to pre-weaned piglets, suggesting a role in the microbial succession that occurs during weaning.[3]
