Abstract A total of 518 fecal samples collected from 1 83 apparently healthy cattle 180 pigs and 155 broilers throughout Japan in 1999 were examined to determine the prevalence and antimicrobial susceptibility of Salmonella. The isolation rates were 36.1 in broilers 2.8 in pigs and 0.5 in cattle. S. enterica Infantis was the most frequent isolate found in 22.6 of broiler fecal samples. Higher resistance rates were observed against oxytetracycline 82.0 dihydrostreptomycin 77.9 kanamycin 41.0 and trimethoprim 35.2 . Resistance rates to ampicillin ceftiofur bicozamycin chloramphenicol and nalidixic acid were 10 . CTX-M-2
