Abstract

Summary: The ultrastructure of and spores has been examined using the freeze-etching technique. Labelled antibodies have been used in an attempt to locate crystal antigen in the spores of , which have a more complex structure than those of The results of morphological studies and the use of labelled antibodies to stain sections of sporulating cells of suggest a relationship between crystal protein and the sporecoat of the organism. The different aspects of ultrastructure and their relation to crystal structure and formation are discussed.
