S. Aureus Epidemic: A Case Study

Decent Essays

Staphylococci are spherical gram-positive cocci arranged primarily in form of irregular clusters. They are present mostly in the upper respiratory tract and on the other epithelial surfaces of warm-blooded animals. The genus Staphylococci are mainly contains 20 species amongst S. aureus is considered as a common pyogenic agent in humans and several animal species, and constitutes a primary cause of mastitis in dairy cattle (Virgin et al.,, 2009).
S. aureus is one of the most important amongst Staphylococci species. The species is found primarily on human skin, mucous membranes and can also be found in other areas of human contact including soil, water, and food products. The species is capable of causing a wide variety of diseases, including septicaemia, sepsis, wound sepsis, septic arthritis, osteomyelitis, food poisoning, …show more content…

It lives on the skins of humans and animals and can easily be transferred to food products (Mousa.,, et al 2014) Staphylococcal food poisoning represents a considerable social burden in terms of hospital expenses, loss of patient’s working days and productivity, together with the problems and the cost of disposing the contaminated food.
The severity of the infection was varied according to many elements in particular the pathogenicity and virulence of the causative strain. The virulence of S. aureus is generally a multifactorial and due to the combined action of several virulence determinants, which augment tissue colonization, tissue damage, and hence disease (Bien et al.,, 2011), these proteins facilitate the bacterial attachment and colonization within the cellular and extracellular material of the host. Moreover, cellular proteins, protease, and toxins, which inhibit phagocytosis and thus interfere with the ability of the host to actively, hinder infection by a specific immune response. Hemolysin and other enzymes aid the bacterial population in the invasion of the host tissues (Lowy, 2000). S. aureus can bind a variety of proteins
