Porcincola

Porcincolais a genus of Gram-positive, strictly anaerobic bacteria in the familyLachnospiraceae''. The genus was described from the pig intestine and currently contains one validly published species,Porcincola intestinalis''.

Taxonomy

The genus name Porcincola is derived from Latin porcus, meaning "pig", and incola, meaning "inhabitant" or "dweller". The type species is Porcincola intestinalis.

Description

The type species, P. intestinalis, consists of coccobacilli that stain Gram-positive, are non-motile, and grow only under strictly anaerobic conditions. Cells may occur in pairs and can form chains up to approximately 10 μm in length.

Ecology

Porcincola was originally described from the intestinal tract of pigs. The type species, P. intestinalis, was isolated from the feces of an Aachen minipig in Germany.

Although first described from pigs, Porcincola has also been reported in rumen microbiome studies. A longitudinal metagenomic study of calves from birth to approximately 800 days of age identified Porcincola among early-life rumen microbial lineages discussed as part of a persistent auxiliary rumen microbiome. In a 2026 in vitro dairy cow rumen fermentation study, Porcincola was reported as one of the core and most abundant genera in the bovine rumen dataset.
