Arcanobacterium (Actinomyces) pyogenesis an inhabitant of the mucous membranes of the respiratory and genital tracts of a number of domestic animal species. However, following a precipitating physical or microbial insult, A. pyogenescan become an opportunistic pathogen, associated with suppurative infections. The isolation of A. pyogenesfrom the bovine ruminal wall indicated that this organism may also inhabit the gastrointestinal tract of, at least, cattle. To determine whether A. pyogeneswas also present on the gastric mucosa of a monogastric animal, porcine stomachs were cultured for the presence of this organism. Of 13 stomachs samples. A. pyogeneswas isolated from 5 (39%). The identity of the organism was confirmed by PCR with primers specific to the plogene, which encodes the A. pyogeneshaemolytic exotoxin pyolysin. In addition, an isolate from each positive stomach was subjected to 16S rRNA gene sequencing and the identification as A. pyogeneswas confirmed. These data indicate that A. pyogenesmay be resident on the gastric mucosa of pigs. |
