Some Characters of Cl. perfringens Isolated from Fresh and Marketed Processed Meat


This study was carried out a fresh meat immediately after slaughter and a marketed processed cattlemeat (sausage and minced meat). A total of 530 meat samples were examined for the presence of Cl. perfringens, 423 were from fresh meat obtained immediately after slaughtering (108 cattle meat, 101 sheep meat, 100 camel meat and 114 buffaloe meat) and 107 processed meat (57 from sausage and 50 from minced meat). Cl. perfringens was isolated from 204 (48.2%) of fresh meat samples, 61 (56.5%) from cattle, 53 (52.5%) from sheep meat, 45 (45%) from camel meat and 45 (39.5%) from buffaloe meat. The isolation rate of Cl. perfringens was higher in processed meat, it was isolated from 68 (63.6%) of which 45 (78.9%) from sausage and 23 (46%) in minced meat. The processed meat was found to harbour higher viable count ranging between 4 × 102 - 7 × 106 Cl. perfringens cells/gm meat than that Fresh meat in which the number ranged from 102:5 × 106 cells/gm meat. Typing of isolated strains revealed that the majority of it was of Cl. perfringens type A, 2 of type B, 3 of type C and one type D. Sixty strains of Cl. perfringens type A were randomized and tested for heat resistance at 100and the results were recorded. Production of enterotoxin by 10 strains of Cl. perfringens was performed by ligated ileal loop test in rabbits. It was done by injection of whole culture in skimmed milk, cell extracts and concentrated culture filtrates of the organism in the ileal ligated loop of rabbits and the results were recorded.
