Sažetak
Canine otitis externa is one of the most common diseases encountered in veterinary practice. It is estimated to affect between 5 % and 20 % of dogs. Inflammation of the ear canal may result from numerous causes. Otitis caused by different bacterial species commonly occurs as a secondary complication of primary factors that initiate inflammation within the ears. However, selection of appropriate chemotherapeutics in relation to the sensitivity of the etiological agents is extremely important for successful treatment of bacterial otitis. The purpose of this study was to estimate the incidence of isolation of different bacterial species involved in otitis externa in dogs, and to determine the antimicrobial susceptibility of the obtained isolates. Clinical specimens were collected from 200 dogs with clinical signs of otitis externa presented at the Clinic for Infectious Diseases from October 2012 to January 2014. Bacterial growth was noted in 104 (52 %) dogs. The most prevalent isolated bacteria were S. pseudintermedius (57,7 %) and P. aeruginosa (20 %). Other bacteria were isolated in a smaller number of cases. P. aeruginosa isolates had low sensitivity to a wide range of antimicrobials, suggesting that many antimicrobial agents commonly used in Pseudomonas but also in staphylococcal infections in companion animals may not constitute appropriate therapy for canines. Due to the highly variable resistance patterns observed, antimicrobial susceptibility testing is a crucial step in the selection of appropriate therapy in otitis.
