RESUMO

The correlation analysis which has already proved its value in ecology has not yet been applied to the determination of virulence indicators. Its application to a group of Clostridium perfringens type A strains has brought out some characters that may be considered as virulence indicators. This study suggests that the toxicity of the culture supernatant fluids for mice is significantly correlated with the virulence for mice and guinea pigs. A significant correlation was found between the virulence of the fluid cultures for mice or guinea pigs and the coagulation of milk, production of gas (in deep agar), hydrogen sulfide production, and fermentation of glucose, sucrose, maltose, and levulose.
