A total of 154 samples were collected, of which 29 (25,97%) resulted S. aureus. Subsequently, a 48.28% prevalence of MRSA was identified through Cefoxitin 30ug discotheques. The antimicrobial sensitivity to Clindamycin and Trimethoprim + sulfamethoxazole was then carried out with a resistance of 41.38% and 27.59% respectively. On the contrary, Linezolid presented a 100% sensitivity. Finally, it was determined that the prevalence of this microorganism is greater in nurses with 50%.
