A Crystalline Layer is a part of the cell envelope commonly found in bacteria, as well as among archaea. It consists of a monomolecular layer composed of identical proteins or glycoproteins. Nano structure Crystalline Layer has been detected in some foodborne diseases bacteria, for example in Salmonella, Clostridium, Campylobacter, Listeria and Bacillus. Regarding this point that Crystalline Layer protects bacteria from some environmental hard condition. Chemical and bimolecular compounds present this structure in food poisoning bacteria, due to problem in the cure of foodborne diseases. The subject of this study was survey of the role of Crystalline Layer in some food borne diseases bacteria. There is consensus that the existence of this surface structure in bacteria lead to increased resistance into hard physical and chemical agent and pathogenicity in bacteria. Crystalline Layer in pathogen bacteria protection against bacteriophages, phagocytosis, resistance against pH, temperature, pressure, adhesion, stabilization of the membrane and provide adhesion sites for exoproteins due to more pathogenesis, infection resistant and antibiotic resistant in bacteria.
