| Abstract: | Seventeen wild-type strains of the phytopathogenic fungus Cochliobolus carbonum, tested by intraperitoneal injection into mice, were lethal within 48 hr. The lethal effect appeared to be a toxic rather than an infectious process, because death occurred within 3 hr after injection of two of the isolates and heat-killed cultures were lethal. Assays of ascospore progeny from two crosses involving three isolates indicated that the toxic metabolites were under genetic control and quantitative regulation. Studies of the toxicological, cultural, and chemical characteristics of these three strains indicated that more than one murine toxin was present. |
