RESUMEN
Introducción. Los estudios de Staphylococcus aureus en personal de salud permiten reducir su diseminación en las infecciones intrahospitalarias y mejorar la calidad de vida de los pacientes. La colonización por S. aureus en personal de salud de un hospital de tercer nivel, se evaluó caracterizándolo fenotípica y molecularmente. Métodos: Una población de 62 trabajadores y 216 estudiantes de medicina, mediante análisis del antibiograma y polimorfismo del gen agr. Resultados: S. aureus colonizó el 30,1% del personal; 17,5% trabajadores, 33,8% estudiantes. El 10,8% fueron meticilino-resistentes, 9 aislados presentaron el gen mecA, ocho resistentes a oxacilina y cefoxitina (88,9% de sensibilidad). La variante II considerada de origen hospitalario, se presentó en el 7,7% de aislados, el agr tipo III de origen comunitario en el 27,6% de aislados meticilino-sensibles. Conclusión. El personal hospitalario presentó colonización por S. aureus de origen hospitalario y comunitario. Es necesario adoptar medidas profilácticas e higiénicas para evitar diseminación y prevenir infecciones.

ABSTRACT
CHARACTERIZATION OF STAPHYLOCOCCUS AUREUS PRESENT IN HEALTH PERSONNEL OF A MID-COMPLEXITY HOSPITAL OF THE CITY OF CALI, 2012
Introduction. Studies of Staphylococcus aureus in health personnel reduce its spread in nosocomial infections and improve the quality of life of patients. The colonization state by S. aureus in health personnel of a tertiary hospital was performed by phenotypic and molecular characterization. Methods: A population of 62 health workers and 216 medical students were evaluated by analysis of antibiotic susceptibility and polymorphism of agr gene. Results: S. aureus colonized 30.1% of staff individuals, 17.5% of workers, 33.8 % of students. 10.8% were methicillin- resistant, 9 isolated harbored mecA gene, and eight were resistant to oxacillin and cefoxitin (88.9 % sensitivity). The agr II associated with hospital source was in 7.7 % of the isolates and agr type III -associated with a community source- was found in 27.6 % of meticillin-sensitive isolates. Conclusion. Hospital health staff showed colonization by S. aureus of both community and hospital sources. To prevent their spread and infections, prophylactic and hygienic measures are necessary.
Keywords. Staphylococcus aureus, Antibiotics, Asymptomatic carriers, health personnel, MRSA.
