The interest in the spore-forming bacteria Bacillus cereus is due to their widespread occurrence and their ability to cause various diseases, mainly of the gastrointestinal tract. Spores of pathogenic microorganisms, including B. cereus, pose a great challenge to medicine, pharmacology and food industry because of their resistance to various environmental factors. The properties of the spores are determined by their ultrastructure. The basic structure of spores is conservative and consists of the exosporium, shell, outer membrane, cortex, inner membrane and core [1]. However, the outer layers of the spores, including the exosporium, vary between species and strains, allowing the features of their components to be compared by electron microscopy.
