| dc.description.abstract | A cross sectional study to determine the antimicrobial profile of salmonella isolated from milk and fecal samples of apparently healthy cattle found in dairy farms of Debrezeit was undertaken from November 2013- April 2014. A total of 296 samples (148 fecal and milk each) were collected and processed in college of veterinary medicine and agriculture debrezeit. The overall prevalence of salmonella was found to be 12.8%. Prevalence of 2.0 and 10.8% was observed from milk and fecal samples respectively. The isolates were tested for the effect of 11 antimicrobial by disk diffusion technique they have indicated 89.5%, 100%, 42.1%, 63.3%, 15.8%, 10.5%, 31.6%,42.1%, 52.6% resistant to amoxacyline, tetracycline and gentamycin, kanamycin, trimetoprim, streptomycin, cotrimoxazol, chloramphenicol, nalidixic acid and cefoxitin respectively no resistance has been found for ciprofloxacin. However no statistical difference (P>0.05) was observed between milk and fecal samples. Totally 8 Multiple Drug Resistance (MDR) pattern were also observed. The highest MDR was for three antibiotics with the combination Amc, Te, Cn being more frequent. In general MDR to three, seven and eight antibiotics dominate the resistance patterns (31.6%, and 21.1% each). From this study we conclude that milk can be a potential source of drug resistant salmonella infection and multidrug resistance is developing due to unmonitored and inappropriate use of drugs in dairy farm which needs due consideration as it affects the dairy industry and the people at large. | en_US |
