A number of 44 samples were examined for bacterial pathogens encountered in external ear inflammation in dogs of different ages and breeds. On bacteriological culture, Staphylococcus aureus,Staphylococcus epidermidis,Pseudomonas aeuroginosa,Escherichiacoliand Klebsiella pneumonia, represented the bacterial isolates.All isolates were subjected to antimicrobial sensitivity testing using antibacterial agents. The obtained results indicated that S. aureus was the most common isolated bacterial species.The antibiogram assays showed that allbacterial isolates were sensitive to piperacillin/tazobactumand imipenem/meropenenum. Staphylococcus spp. isolates were sensitive to Linezolid and Vancomycin. In conclusion: To control otitis externa (OE), susceptibility testing is be applied on isolates to guide the veterinarians to choose the most effective therapeutic regimen.
