Prevalencia y fenotipificación de microorganismos bacterianos resistentes a antibióticos aislados de las pantallas táctiles de teléfonos celulares pertenecientes a estudiantes de la Titulación de Bioquímica y Farmacia de la Universidad Técnica Particular de Loja durante el periodo Abril - Agosto 2018

Abstract

Abstract:The external part of a mobile device, surprisingly, is a surface in which a number of pathogenic microorganisms coexist. Its constant use makes it become a bacterial source as harmful as any other known. Everything previously raised, makes its study an unavoidable objective. Our objective in the realization of this work consisted in establishing the prevalence in these accessories of microorganisms resistant to methicillin and beta-lactams isolated on the touch screens of the cell phones belonging to the students who studied the components of Clinical Microbiology and Microbiology II, during the period April - August 2018. It was a descriptive observational study, from 74 mobile devices; to which a touch screen swab was made. Subsequently the isolation and bacterial identification through presumptive and definitive tests. The data obtained were tabulated using the statistical program SPSS 20.0. Observing the existence of factors that influence pollution and proliferation as they are: the use of the device during food intake, improper hand washing after the use of bathroom, among others. Among the isolated bacteria stand out: Staphylococcus saprophyticus, Staphylococcus epidermis, Staphylococcus aureus, among others.
