The antimicrobial drug resistance pattern of Salmonella entericaserovar Typhimurium of various meats received in Veterinary Research Institute (VRI) was evaluated for the period of 2009 to 2012. A total of 64 strains of Salmonella typhimurium were isolated from beef, pork and chicken meat. All isolates were tested for resistanceagainst 12 different antimicrobial agents. Antimicrobial susceptibility of the isolates was conducted using the disk diffusiontechnique according to the standards of Clinical and Laboratory Standards Institute (CLSI, 2007). 49 isolates (76.5%) showed multidrug resistance (MDR) and they originated from pork (100%), chicken (75.0%) and beef (58.8%). Salmonella typhimurium isolates from beef and pork showed multiple antimicrobial resistance to tetracycline, streptomycin, nalidixic acid and ampicillin, while isolates from chicken meat showed common profile of multiple antimicrobial resistance to sulphamethoxazole, sulphonamides andtetracycline. Ceftriaxone and cefotaxime recorded as most sensitive drug for Salmonella typhimurium isolates.
