Abstract

The survey comprised 5870 dogs with surgical diagnoses for the period 1 January 2010 to 31 December 2014, out of which 269 (4.58%) were diagnosed with otitis. The total number of isolates was 53: 17 coagulase-positive staphylococci, 2 beta-hemolytic staphylococci, 16 Pseudomonas aeruginosa, 7 Proteus mirabilis, 9 Malassezia pachydermatis, and 2 Candida spp. Bacterial and fungal infections were most frequently encountered in the summer (26; 49.06%) then in the autumn (13 isolates, 24.54%), and winter and spring (7 isolates, 13.21%). The highest number of isolates (21.4%) was resistant to chloramphenicol, followed by those resistant to gentamicin (16.6%), enrofloxacin (14.3%), and amoxicillin/clavulanic acid (9.5%). Head shaking was the commonest clinical sign (59.48%), followed by ear scratching (88 dogs), pain (81 dogs), and ear discharge (71 dogs). Acute otitis cases were 53.53%, followed by chronic (29.37%) and recurrent cases (17.10%).
