Lecithinase-negative variants of Clostridium perfringens; the identity of C. plagarum with C. perfringens.

Identity of Clostridium plagarum (Prévot) com. nov. (1938) with C. perfringens was demonstrated in the tests for the cultural and biochemical properties, DNA-DNA homology, susceptibility to C. perfringens-specific lysin, complementary synthesis of C. perfringens theta-toxin between C. plagarum and theta-toxin-negative mutants of C. perfringens, as well as the tests for gas-chromatographic patterns.
