Investigação da contaminação bacteriana em fones de ouvido e perfil de resistência aos antimicrobianos

Abstract

Every day the human body meets various inanimate object, some like headphones are easily carried and are in direct contact with the skin and ear canal. This study aimed to investigate different bacteria may be present in headphones and if they have a resistance profile. For this purpose, collections were performed by sterile swab rubbing in the earphones of 30 volunteers from the university community, then cultivated in culture media for differentiation of Gram negative and positive bacteria and specific tests for identification and resistance of microorganisms. Subsequently, the morphology of the earphones and the material of its composition were evaluated, seeking to verify if these factors influence the bacterial contamination found. Among the recovered 60% were enterobacteria, including with multiresistance profile vulnerability recovery such as ESBL and MLSBi. The study points to a wide variety of pathogenic bacteria in the headphones investigated and that such bacteria in favorable conditions can directly influence human health.
