Otitis externa (OE) is the term used to describe inflammation of the external ear canal. This disease has many etiologies, occurs in several species and is particularly common in dogs. The resident microbiota microorganisms are commonly involved in the OE etiopathogenesis, being frequently appointed as perpetuator agents. The aim of this study was to investigate the microbiological profile of dogs with healthy ears and of others with otitis in the metropolitan region of Recife, Pernambuco, Brazil. With the aid of sterile swabs, samples of right and left ear of 41 dogs, 11 with and 30 without OE, were collected. Bacterial and fungal isolation was performed with cultured samples; positivity was observed in 80% of animals with healthy ears, with the presence of more than one microrganism in 38 samples (63.3%), whereas in dogs with OE, the positivity was 95.3% with polymicrobial infection in 77.3% samples. With regard to the genus, the microbiological profile was identical between healthy and diseased dogs. The microrganisms isolated were Staphylococcus sp., Micrococcus, Bacillus sp., Streptococcus sp. and Malassezia sp. |
