Abstrakt: Clostridium perfringens (C. perfringens) is one of the most important pathogen that is widely distributed in all over the world and responsible for many diseases among life stock. C. perfringensis responsible for toxin production in the intestinal tract of rabbits and that was considered the main cause of enteritis and enterotoxaemia causing high mortality especially at the early weaned rabbits, which lead to high economic losses in rabbits industries. So, this study was aimed to evaluate the ability of oil adjuvant containing sonicated BCG vaccine to increase the immune response for rabbit clostridial enterotoxaemia and bloat vaccine. The study was conducted on twenty New Zealand rabbits divided in to two groups each of 10,Group A(control group)was vaccinated with alpha toxoid adjuvanted with aluminum hydroxide gel at two doses with 21 days apart inoculated subcutaneously, Group B was vaccinated with BCG sonicated oil adjuvant vaccine of alpha toxoid of C. perfringens type A, with 2 doses subcutaneously with 21 days. Rabbits in group (B) which vaccinated with BCG sonicated oil adjuvant vaccine of alpha toxoid of C. perfringens type A, their serum contain antibody titer of 8 IU/ml(7.1 IU-8.0 IU/ml) greater than that of control group (A) vaccinated with aluminum hydroxide gel adjuvant vaccine (W=0, p=0.0001503). From this study, we can concluded that the vaccination of rabbits with oil adjuvant containing sonicated BCG vaccine is effective to increase the immune response against rabbit clostridial enterotoxaemia and bloat vaccine.
