Characterization of a toxin-deficient Clostridium perfringens strain, KZ1340.

abstract：:Cattle enterotoxemia caused by Clostridium perfringens toxins is a noncontagious, sporadic, and fatal disease characterized by sudden death. Strategies for controlling and preventing cattle enterotoxemia are based on systematic vaccination of herds with toxoids. Because the process of producing conventional clostridia...
