Intestinibaculum

Intestinibaculum is a genus of strictly anaerobic, Gram-positive bacteria in the family Erysipelotrichaceae. It was first described in 2019 following the isolation of its type species, Intestinibaculum porci, from the small intestine of a pig.

Taxonomy and nomenclature

The genus Intestinibaculum was proposed in 2019 after the isolation and characterization of strain SG0102^T from the small intestine of a pig. The genus name is derived from Latin: "intestini" (intestine) and "baculum" (rod). The species epithet "porci" refers to its porcine origin.^[1]

Morphology and physiology

Intestinibaculum species are rod-shaped, non-motile, Gram-positive, and strictly anaerobic. The type strain SG0102^T grows optimally at 37 °C and pH 7.0. It tolerates up to 3% NaCl but does not grow above that concentration. Cells are catalase-negative and fermentative. Major fatty acids include C_16:0, C_16:0 DMA, and C_18:2 ω9,12c. Peptidoglycan contains meso-diaminopimelic acid.
