Detección de staphylococcus aureus sarm mediante pruebas fenotípicas y automatizadas en personal de salud del Hospital General Privado Ambato

Abstract

Methicillin-resistant Staphylococcus aureus (SARM) is a bacterium of high medical importance, the spread at the hospital level is due to aerosolization and direct contact between healthcare personnel and patient. The present study is of current interest because this microorganism, if not promptly detected, can be pathogenic and cause serious infections. The purpose of this study is to identify SARM at the nasal and hand level in the health personnel of the Ambato General Private Hospital, in addition the antimicrobial sensitivity profile of the detected strains will be prolonged. A descriptive, quantitative cross-sectional study was undertaken with a sampling of nasal and hand swabs from 29 health professionals. Isolation and identification was carried out using conventional methods according to CLSI criteria and by the VITEK 2 COMPACT automated equipment. The results were analyzed using the IMB SPSS 29 system. 17.4% of the samples analyzed presented S. aureus, 80% from nostrils and 20% from hands, in addition, SARM methicillin-resistant strains in 3.4% corresponding to nasal samples. Therefore, the presence of S. aureus in health personnel is a risk and therefore its prompt diagnosis is paramount, as well as encouraging biosafety measures in all personnel working in health institutions, requiring special attention to prevent infections at a systemic level.
