Staphylococcus aureus nosocomial skin and soft tissue

Introduction: Staphylococcus aureus is one of the most isolated nosocomial microorganisms and exhibits high resistance to antimicrobial ones. Objective: to characterize the behavior of Staphylococcus aureus isolated from skin and soft tissue. Method: A transverse descriptive investigation was realized at "Arnaldo Milián Castro" Hospital about Staphylococcus aureus nosocomial isolated from skin and soft tissue in hospitalized patients from 2003 to 2012. The sample was of 835 isolations, the results were presented in tables and graphs and a statistical regression analysis and seasonal factors was performed. Results: the nosocomial isolations represented 21.6% of the totality of Staphylococcus aureus, the surgical services reported the highest insolation values (78%), and the endemic corridor showed epidemic peaks in the months of April and November and antimicrobial resistance was lower for chloramphenicol and trimethoprim/sulfamethoxazole. Conclusions: one of four isolatations of Staphylococcus aureus is nosocomial, the endemic corridor identified epidemic outbreaks without coincident with the historical behavior of the series in which the maximum peak correspond to October, Staphylococcus aureus showed profiles of high resistance for all used antimicrobial and the chloramphenicol and the trimethoprim/sulfamethoxazole showed lower values of antimicrobial resistance.
