ABSTRACT

Staphylococcus aureus is one of the most important microorganisms in medical care, emerging in the community and in the hospital environment. The objective of this work is to present an update on the elements of clinical interest of the molecular microbiology of Staphylococcus aureus. To make this review, the databases of Scielo, HINARI, Pubmed-Medline and bibliographies available on the subject were used and the descriptors used were: Staphylococcus aureus, methicillin resistance, genes, molecular epidemiology, virulence and the combination between them. We reviewed the elements that determine its virulence factors, antimicrobial resistance, the versatility of pathogenic strategies, the ability to survive in different conditions, the evolution and virulence of the processes it produces. Likewise, the diagnosis of resistance, molecular diagnostic techniques, with their utilities, limitations, advantages and disadvantages, and the studies of these subjects in recent years in Cuba were addressed, since methicillin-resistant strains of Staphylococcus aureus circulate, but not the real situation is known. It is recommended the convenience and need to organize and harmonize clinical, epidemiological and microbiological studies, which can show what is the current situation of this microorganism and its infections, that provide data of its molecular evolution, to evaluate the tendency of the situation found, that allow decisions for the development of surveillance and control programs and revitalize the means and methods of diagnosis. Current knowledge of the subject, interpretation of new results and scientific exchange is important.
