Antibiotic resistance is a major global public health challenge. Close human-animal contact and overuse of antibacterial agents in veterinary medicine increase the risk of spreading drug resistance. Salmonella, as a leading cause of infectious gastroenteritis in humans and animals, holds particular importance in epidemiological studies. In this study, cloacal swab samples were collected from 150 ornamental birds with diarrhea and transported to the laboratory. After isolation of presumptive Salmonella isolates based on biochemical tests, antibiotic susceptibility testing was performed using the disk diffusion method. Tested antibiotics included kanamycin, trimethoprim-sulfamethoxazole, cefixime, tetracycline, and ampicillin. Data were analyzed using SPSS at a significance level of 0.05. Salmonella was isolated from 22% of the studied birds. The highest resistance rates were observed against ampicillin (100%), and kanamycin (93.9%) while the lowest resistance was to trimethoprim-sulfamethoxazole (9.1%) and tetracycline (72.7%). The largest mean inhibition zone diameter was recorded for trimethoprim-sulfamethoxazole (20.06 mm) and the smallest for ampicillin (0.84 mm). Salmonella prevalence was highest in canaries, Brazilian parrots, and pigeons. These findings suggest that ornamental birds with diarrhea could be potential reservoirs of resistant Salmonella strains. Therefore, performing antibiotic susceptibility testing before prescribing drugs, rational use of antibiotics, and continuous monitoring of microbial resistance in ornamental birds are of great importance.
