[Electron microscopic study of normal Bacillus anthracoides spores and after exposure to a chloroactive disinfectant].

The fine structure of Bacillus anthracoides spores is similar in general to that of other, taxonomically related species of spore forming bacteria. However, the former is characterized by a well-developed multilayered exosporium and the heterogeneous structure of an envelope. The lethal effect of a chloroactive disinfectant (2/3 of calcium hypochlorite basic salt) is caused by changes in the structural organization of spores, which interferes with the normal permeability barrier and metabolic processes.
