Abstract:
In present investigation detailed cultural examination of all the 52 samples collected and processed from bacterial dermatitis dogs revealed positive for 72 isolates. Out of these 52/72 were Staphylococci spp. (72.22%) and among these 34 isolates were S. intermedius (65.38%), 12 were S. aureus (23.07%) and 6 were S. epidermidis (11.53%). Whereas, twenty of these samples also revealed Klebsiella spp. in 9 (12.5%), Pseudomonas spp. in 8 dogs (11.11%) and E. coli in 3 (4.17%) that were mixed with Staphylococci. The occurrence of single and mixed bacterial infection was 61.53 and 38.47 %, respectively. In this study 27 dogs (51.88%) with bacterial dermatitis were associated with other conditions like demodicosis (17.30%), Malassezia dermatitis (9.61%), tick infestation (7.69%), sarcoptic mange (5.76%), hypothyroidism, flea infestation and lice infestation (3.84%). In-vitro antibiotic sensitivity test was done on pure isolates by using conventional antibacterial agents and observed enrofloxacin had 100% efficacy against S. intermedius, S. epidermidis, E. coli and Klebsiella, while 83.3% and 75.00% sensitivity was recorded against S. aureus and Pseudomonas spp. respectively. Clindamycin had 100% efficacy against S. intermedius, 83.3% efficacy aginst S. aureus and S. epidermidis, E. coli, Klebsiella, Pseudomonas spp, are comparatively resistant
