Sporulation-dependent phagelike particles in inclusion-forming Bacillus species.
Phagelike particles, which have been observed in sporulated cells of Bacillus medusa, were found to appear at about late stage II in all subspecies of Bacillus thuringiensis toxic to mosquito larvae. All phagelike particles were similar in size and shape and when purified possessed capsid proteins of similar molecular weights and immune reaction. The synthesis of the major capsid protein occurred at the same time as complete phagelike particles were detected by electron microscopy. The production of phagelike particles was not essential for sporulation.
