Resumo

The asymptomatic nasal carriers of Staphylococcus aureus methicillin resistant have been identified as a risk for nosocomial and community infections. In the present study we determined the prevalence of nasal carriers in the health care staff of the Hospital I Florencia de Mora of Trujillo city, Peru. in 2011. The investigation cross-sectional, representative sample with a total of 123 workers. We used the Chromagar MRSA culture for isolation and same biochemical tests to identified the MRSA. The groups of study were physicians, nurses and technical personnel of health, auxiliary and administrative staff, who filled a questionnaire and a nasal swab sample was taken and then we took to the laboratory. The results of the investigation were: in 15.4 % turned out to be positive for nasal carrier of Staphylococcus aureus and 6.5% positive of the total of workers for SAMR. In this investigation we evaluated some factors of risk, age, habits of white coat changing; and as protective factors the good practice of hand washing during the work in the Hospital, as well as the white coat washed three times per week, or maybe other times of wash, also evaluated the exhibition to infectious material or hospital waste and the health worked who was with contact with this materials. We concluded that the condition of nasal carrier of Staphylococcus aureus particularly the resistant methicillin plays an important role in the pathogeny and epidemiology of the infections, for what it is necessary to apply the procedure of biosafety in a suitable way, to avoid nosocomial infections. For the moment the recommendation we suggest for this hospital is to involucrate more to the health workers and the administratives workers for practice good habits of higyene, and same good practice in manipulate the materials that are considered infective.
