The toxic parasporal protein of Bacillus thuringiensis strain 562-5A, solubilized both in gut juice and under alkaline conditions, has been studied by serological methods and compared with similar preparations from B. thuringiensis var. thuringiensis. It was found that strain 562-5A differs in at least one antigen from B. thuringiensis var. thuringiensis but shares at least four antigens with it. Crystals dissolved in Bombyx mori larval gut juice and subjected to electrophoretic separation gave fractions that were serologically similar but of different toxicity.
