Abstract

The goals of this study were to identify microorganisms in dogs' ear canals through cytological and microbiological examination, and evaluate their association with otoacariasis and its clinical signs. Otodectes cynotis infestation diagnosis was achieved by bilateral otoscopy, and by parasite viewing on cerumem under stereoscopic microscope, representing the parasitological exam. Ear discharge was also collected from each canal to fix cytology slides and for microbiological isolation, but this last sample was collected with sterile swab. Among the 250 studied animals, 15 (6%) had ear mites. There was an association between the parasite and external clinical otitis specially as established by auricular erythema (P < 0,001) and excessive production of ear discharge (P = 0,0016), as well as ear pruritus observed by the owners (P < 0,001). It has been suggested that these associations can be an effect of the infestations. There was also an association (P < 0,01) between otoacariasis and microorganisms detected by cytological exam in both ear canals of each dog. However, there was no association (P = 0,04 e P = 0,07) between the presence of ear mite and microorganisms detected by microbiological exam of right and left ears.
