The most typical cause of bovine mastitis is staphylococcal enterotoxin C. The primary enterotoxin gene of S. aureus isolated from cows with mastitis, according to other researchers, is called sea. Three enterotoxin-like genes have shown super-antigenic activity but no emetic qualities, two enterotoxin genes (seg and sei), and two enterotoxin genes make up the cluster (selo, selm, and seln). The gene discussed is SELENOO; the disease is Bovine mastitis.
