Ocorrência e perfil de resistência antimicrobiana dos agentes causadores de otite externa em cães

Abstract

Canine otitis externa is the term used to describe inflammation of the external auditory canal, which has a multifactorial etiology including factors that perpetuate the inflammation / infection cycle. he aim of this study was to characterize the clinical and microbiological profile of the causative gents of otitis, as well as resistance profile. It was made a clinical otological evaluation, pidemiological tests, culture and antibiogram of 132 animals attended at the Veterinary Hospital f the Federal University of Mato Grosso. The cases occurred predominantly in dogs with no efined race, between 7 months and 16 years old and with no sexual predilection. The presence of pruritus and purulent secretion was the most observed data. Staphylococcus spp (74.2%) and Malassezia spp (54.5%) were more isolated, but other important agents such as Pseudomonas spp, Corynebacterium spp and Proteus spp. were also isolated. The most sensitive antibiotics tested for Staphylococcus ssp isolates were cephalexin (78.1%), Polimixin B (75.7%) and among the class that presented less effectiveness stands out the quinolones (enrofloxacin 29.5%, marbofloxacin 29, 5%, ciprofloxacin 32.6%) and the sulfonamides (sulfa + trimetropine 22.7%).
