This study was undertaken to characterize otic microflora encountered in dogs with clinical signs of otitis externa and to determine its role in causing the disease. For this purpose 73 otic samples from normal dogs and 149 otic samples from dogs with different clinical stages of otitis were microbiological evaluated. The most common pathogens in the etiology of otitis include members of Staphylococcus genus, Streptococcus genus and yeast from Malassezia genus. From normal dogs Malassezia canis was isolated as a pure culture or with staphylococci and streptococci in 32 samples, representing 43.8%, staphylococci were recorded at a frequency of isolation (in pure and mixed cultures) of 32.9% and streptococci were isolated in 17 pure or mixed cultures, representing 23.3%. Staphylococcus aureus, Pseudomonas aeruginosa and Proteus spp. were not isolated in samples taken from dogs without ear problems. From dogs with varied clinical stages of otitis, Malassezia canis reported a frequency of isolation (in pure or mixed cultures) of 33.3%, staphylococci were isolated in 22.4% and streptococci in 19% from samples, in pure or mixed cultures. Staphylococcus aureus and Pseudomonas aeruginosa were isolated both in pure cultures and mixed cultures and Proteus spp. only in mixed cultures.
