    Introduction: The main reservoir of Staphylococcus aureus is human nostrils. It is known that nasal carriers of Staphylococcus aureus are at increased risk of 3-6 fold greater risk to get infections from this germ. In its variety methicillin resistant shows itself as one of the most important hospital pathogens. Objective: To determine the prevalence of nasal carriage of Staphylococcus aureus in hospital personnel and their antimicrobial susceptibility pattern. Cuenca 2010. Method: It is a cross-sectional design carried out in Vicente Corral Moscoso Hospital and División III Ejército Tarqui. The studied population was composed by 150 people who work in intensive care units, neonatology wards and operation rooms. Samples were collected by nasal swab, transported in Stuart's medium, cultivated on blood agar and mannitol agar. We performed Gram stain, catalase test, coagulase, DNase and it was performed antimicrobial susceptibility testing by the disc diffusion method. We made a descriptive statistical analysis for a better understanding and interpretation of the data. Results: 55 strains of Staphylococcus aureus were isolated from the tested crops. The prevalence was 37%. The most colonized personnel was the neonatology staff with 39%. Most carrying was observed in medical personnel with 50%.They were susceptible to trimethoprim-sulfamethoxazole, and vancomycin 100%; cefoxitin 94,55; gentamicin 90,9%; clindamycin 89%; tetracycline 87,3%; erythromycin 49,1%; 18,2% penicillin. Conclusion: 37% of hospital staff was nasal carriers of S. aureus, being potential spreader. The antimicrobial susceptibility of this microorganisms decreased compared to methicillin.
