The purpose of research is improving the efficiency of differential diagnostics of dogs and cats surface otitis. The microbiocenosis of the external auditory canal of dogs and cats consisted mainly of fungi of the genus Malassezia and Candida, bacteria of the genus Staphylococcus, Streptococcus, Micrococcus, Corynebacterium, Bacteroides, Escherichia, Proteus, Klebsiella, Enterococcus, Bacillus and Pseudomonas. Representatives of Malassezia pachy-dermatis were identified from 52 (67.54%) dogs and 6 (33.34%) cats and cats. M. obtusa were isolated from 5 (6.49%) dogs and 2 (11.12%) cats and cats, M. globosa was isolated for 5 (6.49%) dogs and 2 (11.12%) cats and cats. M. furfur are allocated from 3 (3.90%) dogs and 3 (16.67%) cats and cats, M. restricta is allocated from 7 (9.09%) dogs and 2 (11.12%) cats and cats. Representatives of Candida albicans were identified from 3 (3.90%) dogs and 1 cat (5.56% of animals), C. parapsilosis was detected in 2 (2.60%) dogs and 2 (11.12%) cats. M. pachy-dermatis fungi are isolated in 22 dogs, 2 cats and cats with acute otitis media, and in 30 dogs and 4 cats and cats in chronic course. M. restricta is isolated from 3 dogs and 1 cat for acute otitis media, and 4 dogs and 1 cat for chronic disease. M. furfur are isolated from 3 dogs, 3 cats and cats, M. globosa – from 5 dogs, 2 cats and cats are isolated from acute otitis media. M. obtusa is isolated from 5 dogs, 2 cats and cats in chronic otitis media. Mushrooms Can-dida albicans are isolated from 3 dogs and 1 cat, C. parapsilosis – from 2 dogs and 2 cats with chronic otitis media. In the development of otitis from dogs and cats, the leading role is played by lipophilic yeast-like fungi Malassezia, Candida and bacteria of the genus Staphylococcus, which possess pathogenic properties and acquire persistence factors during the formation of fungal-bacterial and bacterial associations.
