Otitis externa is a common inflammatory condition in dogs that can be caused by various types of bacteria. The primary objective of this study was to determine the bacteriological profile of otitis externa cases in canines attending veterinary clinics in the city of Rivas. A descriptive cross-sectional study was conducted, including 20 canines with symptoms compatible with otitis externa. The dogs were sampled using a swab for bacteriological culture and underwent complete blood counts. A clinical-epidemiological record was also completed. Antibiotic susceptibility of the isolated bacteria was performed by antibiogram based on the disk diffusion method with the antibiotics amoxicillin plus clavulanic acid (AMC), gentamicin (CN), tetracycline (T), ciprofloxacin (CIP), ceftriaxone (CRO), cephalexin (CL) and trimethoprim/sulfamethoxazole (SXT). 55,0% (11/20) canines with bacterial infections were identified. The most frequently found bacteria was coagulase-negative Staphylococcus (CNS) present in 54.5% (6/11) of positive cases; meanwhile, Pseudomonas spp was isolated from 27.3% (3/11) and Klebsiella spp in 18.2% (2/11) of positive cases. In the antimicrobial resistance profile of the isolated bacterial strains, it was found that 63.7% of the strains were resistant to AMC and CL, while resistance to CN was observed in 45.5%, for T, CIP and CRO resistance was found in 18.2%, finally, SXT was not effective against 9.1% of the isolated bacteria. The results indicate a high frequency of otitis externa in canines and high proportion of antimicrobial resistance against penicillin.
