Avirulent Clostridium perfringens strains obtained by euflavine treatment.

G Paquette, V Fredette.   

Abstract

Clostridium perfringens was incubated in the presence of euflavine (EU); the resistant mutants which were thus isolated had highly reduced capacity to release alpha-toxin. This fact was confirmed by lecithinase determinations and by immunoelectrophoresis. Injected into guinea pigs and into 6- to 7-day-old chicks, these mutants were completely avirulent. A study of their properties indicated biochemical differences between wild types and mutants.
