Disclosed and claimed is a novel Bacillus thuringiensis isolate designated B.t. NRRL B- 18721 which has activity against dipteran insect pests. Thus, this isolate, or mutants thereof, can be used to control such insect pests. Further, genes encoding novel delta-endotoxins can be removed from the isolate and transferred to other host microbes, or plants. Expression of the delta-endotoxins in such hosts results in the con- trol of susceptible insect pests in the environment of such hosts.

A vaccine for the prophylaxis of dermatophyte infection in animals, such as guinea pigs, cats, rabbits, horses and lambs comprising a suspen- sion of killed T. equinum, T. mentagrophytes (var. granulare), M. canis and M. gypseum in an effective amount combined with an adjuvant. The vaccine of the invention contains advan- tages over prior art dermatophyte vaccines in that it reduces the risk of infection in inoculated animals and persons utilizing the vaccine and provides cross-immunity.
