Staphylococcus aureus primarily colonizes the nasal passage as well as in oral cavity, skin and gastrointestinal tract it grows at temperature ranging from 15’c-45’c by aerobic respiration or fermentation that produced lactic acids. Staphylococcus aureus is a multi-dimensional pathogen that colonizes and infects only animals, including humans, with immune systems the organism causes large numbers of infections worldwide, both relatively benign and highly serious, through its production of colonization factors and three tiers of virulence factors which interfere with immune. Staphylococcus aureus virulence factors and disease the genus staphylococcus is composed of gram-positive bacteria with diameters of 05-15 μm.
Staphylococcus aureus:decreased activity, however, against penicillinase-producing staphylococcus aureus, a common bacterial agent in food poisoning. Staphylococcus was first discovered in 1880 by alexander ogston currently, more than 30 different species of the genus has been identified. The human microbiome can play a key role in host susceptibility to pathogens, including in the nasal cavity, a site favored by staphylococcus aureus however, what determines our resident nasal microbiota—the host or the environment—and can interactions among nasal bacteria determine s aureus colonization.
