Abstract

Background: The superficial layer is a part of the cellular envelop that is seen in bacteria and archaea. This superficial layer is a single layer structure composed of subordinate proteins or glycoproteins. The superficial layer is the outer most cellular structure that is in the exchange and reaction around environment with bacteria. This structure has very diversity in bacteria different types.

 

 

Materials and Method: The related articles to superficial layer were extracted of these articles: Pubmed, Elsevier Science, and Yahoo, from 1995 to 2010 years. For this purpose keywords were searched including superficial layer, pathogenesis, pathogen bacteria,

 

 

Results: There is consensus in the case of the superficial layer and about the existence of this superficial structure lead to increased pathogenesis in bacteria, in all of the research articles.

 

 

Conclusion: S-layers in pathogen bacteria with bacteria  protection against bacteriophages and phagocytosis, resistance against low pH, adhesion, stabilisation of the membrane  and providing adhesion sites for exoproteins caused pathogenesis, infection resistant and  antibiotic resistant in host.

 

 

The result of this study shows the prevalence of considerable S-layer in pathogen bacteria and this matter identified the bacteria generator importance of this structure in the laboratory
