“Identificación de agentes bacterianos causantes de infecciones de oído y su relación con la resistencia a los antimicrobianos”
(Universidad Técnica de Ambato - Facultad de Ciencias de la Salud - Carrera de Laboratorio Clínico, 2018-02-01) Arias Negrete, María Fernanda.; Tabares Rosero, Lourdes Gioconda Dra. Mg.
The aim of the present study was to identify the bacterial agents that cause ear infections and their relationship with antimicrobial resistance for which a descriptive, transversal study is proposed, where bacteria were identified present in the ear secretion samples from patients using protocols established by CLSI and also bacterial resistance using the Kirby-Bauer antibiogram method. The 55 patients who participated in the study were in the age range between 18 to 55 years. From cultured samples the isolated bacteria were: Staphylococcus epidermidis with a percentage of 62.0%, Staphylococcus aureus with a percentage of 32.0% and Pseudomonas aeruginosa with a percentage of 6.0%. By relating the bacteria identified with ear infections we can say that Staphylococcus aureus and Pseudomona aeruginosa are considered pathogenic bacteria and Staphylococcus epidermidis is considered a normal ear microbiota. It is possible to indicate that Pseudomonas aeruginosa is the only one that presents resistance to the antimicrobials of habitual use to the ear treatment infections.
