Streptococcus porcorum is a species of Gram-positive, catalase-negative, coccus-shaped bacteria within the genus Streptococcus. It was first described in 2011 following its isolation from domestic pigs and wild boars in Spain and Chile.[1]
Streptococcus porcorum was initially characterized from clinical specimens from pigs with respiratory and joint disorders and healthy wild boars [1].. Based on 16S rRNA gene sequence analysis, the species showed closest phylogenetic relatedness to Streptococcus suis, but DNA–DNA hybridization values were significantly below species delineation thresholds, supporting its designation as a novel species within the genus Streptococcus.
Morphology and physiology
Cells of S. porcorum are spherical to ovoid cocci, typically 0.5–1.0 μm in diameter, occurring singly, in pairs, or in short chains. They are non-motile and facultative anaerobes. On blood agar plates, they produce α-hemolytic colonies approximately 1 mm in diameter after 24–48 hours of incubation at 37 °C.
