CLOSTRIDIUM CHAUVOEI-SEPTICUM-NOVYI-SORDELLII-PERFRINGENS TYPES C AND D- PASTEURELLA HAEMOLYTICA BACTERIN-TOXOID
One Shot Ultra 7 is for vaccination of healthy cattle as an aid in preventing blackleg caused by Clostridium chauvoei, malignant edema caused by Cl. septicum, black disease caused by Cl. novyi, gas-gangrene caused by Cl. sordellii, enterotoxemia and enteritis caused by Cl.perfringens types B, C, and D, and bovine pneumonia caused by Mannheimia (pasteurella) haemolytica type A1. Although Cl. perfringens type B is not a significant problem in North America, immunity is provided by the beta toxoid of type C and the epsilon toxoid of type D. The freeze-dried component is a preparation of inactivated whole cultures of M. haemolytica propagated to increase the production of leukotoxin and capsular and cell-associated antigens. The liquid component consists of killed, standardized cultures of Cl. chauvoei, Cl. septicum, Cl. novyi, Cl. sordellii, and Cl. perfringens types C and D, with a special, water-soluble adjuvant (Stimugen®) to enhance the immune response.
