Abstract

The study was conducted to identify the common bacteria leading to dermatitis in canines. The swab samples taken from the dermatitis affected dogs brought to MVC teaching hospital were subjected to Antibiotic Sensitivity Test (ABST). A total of 21 dermatitis affected dogs were screened for the presence of Staphylococcus spp and Escherichia coli, by subjecting swab samples for culture by using MSA and EMB agar respectively. All the samples tested positive for Staphylococcus species while 50% of the samples tested positive for Escherichia coli. Subsequent ABST of the collected swab samples revealed resistance towards Penicillin-G (100%), Amoxicillin (91%) and Cefalothin (91%). Fluoroquinolones like Ciprofloxaxin and Levofloxacin showed 60% and 82% resistance respectively. Cephalosporins such as Cefotaxime and Ceftriaxone were moderately resistant (55% and 45.5% respectively) while Clindamycin and Vancomycin showed high level of resistance (82%) indicating rapid emergence of resistance among Staphylococcus spp and E. coli against a variety of antibiotics tested.
