Idioma: en

Resumen

El propósito de este estudio fue determinar la susceptibilidad a los antibióticos en cepas de P.
aeruginosa aisladas de canes con otitis externa en Callao, Perú. Veinte cepas fueron probadas
en su susceptibilidad a 11 antibióticos mediante el método de disco difusión. Los aminoglucósidos presentaron la mejor sensibilidad (94,4%). La multirresistencia se observó en un 70%. Los animales de raza definida fueron los más afectados (50%). Los aminoglucósidos y
seguidamente las fluoroquinolonas se mantienen como opciones de tratamiento.
