Methicillin-Resistant Staphylococcus aureus (MRSA) Isolated from Dogs with Recurrent Pyoderma

Methicillin Resistant Staphylococcus aureus (MRSA) has been recently growing problem in small animal clinical practice due to increasing resistance to multiple number of antimicrobials. Present study reports about the antimicrobial susceptibility pattern of MRSA isolated from the dogs with recurrent pyoderma. Based on the cultural and biochemical studies 12 isolates were identified as Staphylococcus aureus. Methicillin resistant Staphylococcus aureus was identified based on the disc diffusion method. Fifty percent of the dogs showed the methicillin resistant Staphylococcus aureus isolates which were resistant to almost all the antimicrobials used in the present study. Other fifty percent dogs had methicillin susceptible Staphylococcus aureus which were susceptible to amoxicillin with sulbactum, cefpodoxime with clavulanic acid, enrofloxacin, cephalexin, ciprofloxacin, chloramphenicol, amoxicillin and clavulanic acid, cephadroxil and cefpodoxime. Most of the cultures were resistant to tylosin, lincomycin, erythromycin, azithromycin, gentamicin, amikacin. The alarming antimicrobial resistance and methicillin resistant Staphylococcus aureus recorded in the present study of dogs with recurrent pyoderma suggest maintenance of personal hygiene by the small animal owners.
