Prevalencia de Staphylococcus aureus meticilino resistente (SARM) en el personal operativo del área de Neonatología del Hospital Básico Isidro Ayora de la ciudad de Loja-Ecuador

Abstract

Abstract:Staphylococcus aureus is one of the main causes of bacterial infections at the hospital level. Since the introduction of penicillin and the development of resistance to β-lactams, a new antibiotic was created as a treatment for the infections produced by this bacterium, however, shortly afterwards, strains of S. aureus resistant to methicillin were reported (MRSA), so the objective of this work was to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the operative personnel of the Neonatology area of the Basic Hospital Isidro Ayora of the city of Loja-Ecuador. A total of 184 samples were collected between nostrils and hands of health personnel, finding a prevalence of S. aureus of 17.39% (32/184), of which 50% (16/32) corresponded to MRSA. A greater predominance of this microorganism was reported in nurses with 43.75% (7/16). In the antimicrobial evaluation, a resistance profile was found for Trimethoprim-Sulfamethoxazole of 21.87% (7/32), Clindamycin 40.62% (13/32) and Linezolid 12% (1/32)
