A total of 100 canine wound samples of accidental wound (n=40), pyoderma (n=16), tail wound (n=15), localized anal wound (n=10), otitis (n=8), lacerated mammary wound (n=6) and post-surgical wound (n=5) were taken from Clinic of Surgery and Obstetrics and brought to the Department of Veterinary Microbiology, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tandojam to isolate and identify bacterial species responsible for canine wound infection and their susceptibility to various antibiotics. Samples were confirmed through morphological, culture and biochemical tests. Staphylococcus aureus (67%) was found to be the predominant isolate. It was followed by Pseudomonas aeruginosa (50%), Escherichia coli (40%), Streptococcus pyogenes and Pasteurella canis (38%), Bacillus cereus (36%) and Micrococcus luteus (25%). Staphylococcus aureus was isolated and identified as 40 (55%), 10 (90%), 8(62.5%), 6(66.6%), 15(86.6%), 16(62.5%) and 5(80%) from accidental wound, localized anal wound, otitis, lacerated mammary wound, tail wound, pyoderma and post- surgical wounds respectively. Antibiotics Erythromycin and Ofloxacin were sensitive to S. aureus. B. cereus was sensitive to Ampicillin and Gentamicin. P. canis was sensitive to Ampicillin, Enrofloxacin and Ofloxacin. E. coli was sensitive to Enrofloxacin and Ofloxacin. M. luteus was sensitive to the Ampicillin and Enrofloxacin. P. aeruginosa and S. pyogenes were sensitive to Enrofloxacin.
