Aims: The purpose of the present study was to investigate clinical, bacteriological and histopathological aspects of bacterial skin infections in a population of Iranian domestic dogs with first-time pyoderma. Methods: The study animals were 61 clinical cases of Iranian domestic dogs with first-time pyoderma. The diagnosis of pyoderma was based on the history, the presence of variable gross cutaneous lesions, positive findings on microscopic examination of surface cytology and histopathological findings. Results: Detection of pyoderma amongst adult dogs was significantly higher than puppies (P=0.001). Large breed dogs were presented more frequently for pyoderma in comparison to small breeds (P=0.002). Bacterial species were recovered from 43 of the 61 (70.49%) studied animals. No isolates were recovered from 18 studied dogs. The most frequently recovered bacterial genus was Staphylococcus (32/43 isolates, 74.41%) including: S. epidermidis (22/43 isolates, 51.16%), S. aureus (7/43 isolates, 16.27%), and S. pseudintermedius (3/43 isolates, 6.97%). Staphylococci species resistance was most commonly seen against amoxicillin (94.11%), penicillin (83.35%), and ampicillin (76.47%). Resistant to cephalexin and cefoxitin was 5.88% and 2.94%, respectively. A total of 27 of the staphylococci isolated (84.37%) were resistant to at least one antimicrobial agent and 19 isolates (59.37%) were resistant to three or more antimicrobial drugs. Conclusion: A better understanding of this microbial population is critical for clarification of the pathophysiology of bacterial skin diseases.
