Shakerian A, Jahangiri A, Rahimi E, Dehkordi FS., Enterotoxins from Clostridium perfringens in meat products, Onl J Vet Res., 20(3):158-166, 2016. Toxins in C. perfringens isolated from 70 beef, 50 sheep and goat, 40 camel and 35 sausage, salami and hamburger meat samples are described. Samples were cultured for C. perfringens and analyzed by PCR for alpha (cpa), beta (cpb), epsilon (etx), iota (cpi) and enterotoxin (cpe) genes. C. perfringens was found in 12% raw meat and 9.5% meat products, more frequent in beef (21%) and hamburger (14%) samples. Of 35 Clostridium perfringens positive strains, cpe enterotoxin was detected in 86% and etx in 26% samples. We found a statistically significant (P < 0.009) association between incidence of cpe and etx, cpa and etx (P < 0.015) and cpe and cpi (P < 0.022) enterotoxins.
