A total of 39 salmonella isolates were obtained from organ samples taken from duck, chicken and pig carcasses on 34 farms. They were tested for resistance to 11 antimicrobial drugs. 69.2% of isolates were resistant to at least one drug. Most resistances was shown to tetracycline and sulfamethoxazole while most isolates were susceptible to norfloxacin, enrofloxacin, flumiquine and furazolidone. Ampicillin and cephapirin were effective on the salmonella isolates from ducks and chicken, whereas kanamycin was effective on the isolates from chicken and pigs. Trimethoprim was the drug of choice on the isolates from ducks. Forty eight percent of the isolates were resistant to three drugs or more and these were mainly were the isolates from pigs some of which were resistant to as many as five drugs. Among the isolates, 41% were S. Typhimurium, predominantly from pigs (10/39). The antimicrobial resistance of S. Typhimurium were similar to that of other serovars. It showed, however, more resistance to sulfamethoxazole (81.2% of isolates) and tetracycline (68.7% of isolates).
