The pathogenicity of S.aureus is a result of a number of virulence factors. The structure as comfortably as the excreted products of this organism plays a crucial role in its pathogenicity. The ability to survive and the increasing shield to anti-bacterial agents make it more pathogenic.The factors that determine the pathogenicity of S.aureus are- presence of surface protein (MSCRAMMs) that promotes easy adherence to hosts, invasins which help the bacteria outspread in the host tissues (Gordon & Lowy, 2008), factors present on the surface of the capsule that inhibits phagocyctosis, secretions of toxic substances that damage host tissue, biochemical ability that allows survival in phagocytes and acquired r esistance to strong antimicrobials e.g. Methycillin resistant
