The coagulase-positive staphylococci (CoPS) group includes the species S. aureus, S. pseudintermedius, S. intermedius and S. schleiferi subsp. coagulans. The purpose of this study was to evaluate the antimicrobial resistance of CoPS isolated from dogs with external otitis, using the most commonly antibiotics prescribed in the daily clinic to treat this disease. Samples of ear secretions (n=148) were obtained from 104 dogs with external otitis treated in a veterinary clinic in Lima, Peru in a period of six months. Among them, 113 isolates were identified as Staphylococcus sp, of which 105 were CoPS. The isolates showed the greatest resistance to resistance to ciprofloxacin (27.4%) and the greatest sensitivity to nitrofurantoin (82.1%).

Las otitis externas son parte de los casos más recurrentes en la clínica diaria de animales de compañía. Desde su descubrimiento en 1990, el Staphylococcus schleiferi subespecie coagulans viene siendo reportada con mayor frecuencia en las piodermias y otitis externas caninas, e inclusive, en casos de zoonosis. Por ello, el objetivo principal de esta investigación fue detectar la presencia del Staphylococcus schleiferi subsp. coagulans de otitis externas caninas provenientes de la Clínica de Animales Menores de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos (CAMe FMV UNMSM). Para ello se evaluaron un total de 148 muestras de hisopados óticos, siendo 112 positivas a Staphylococcus sp. y la identificación fue realizada mediante pruebas bioquímicas convencionales (coagulasa, producción de acetoína, y fermentación de trehalosa y manitol) y anál...
