The incidence of infections caused by gram-positive cocci has increased considerably since the 1980s and particularly during the 1990s. Emergence and dissemination of multiresistant microorganisms occur in hospitals as well as in the community, as a result of the interaction of many factors in response to the selective pressure to survive in the presence of the antibiotics used. The objective of the study was to describe the epidemiological, clinical and laboratory characteristics of patients infected by methicillin-resistant Staphylococcus aureus. A descriptive study was conducted of a case series. The sample was composed of children with clinically and microbiologically documented infection by methicillin-resistant Staphylococcus aureus. Of 42 patients hospitalized with infection by S. aureus in the pediatric therapy service of Comandante Pinares Hospital from July 2012 to October 2015, five were selected from whom methicillin-resistant Staphylococcus aureus was isolated by blood and secretion culture and confirmed at Pedro Kourí Tropical Medicine Institute. The results are shown per variable and in frequency distributions. All the patients were treated with vancomycin and 80% had a satisfactory evolution. Complications were related to the organ initially affected as well as to distant organs. Treatment protocols for severe sepsis, septic shock and multiple organ dysfunction were complied with. 80% survival was achieved. It is concluded that infection by methicillin-resistant Staphylococcus aureus is an emerging disease in our environment. An appropriate study of each case leads to better therapeutic management of this infection.
