Abstract

The in vitro drug susceptibility of 83 strains of Bordetella bronchiseptica recovered from Korean pigs with atrophic rhinitis was investigated by the use of disk diffusion method. The majority of the organisms were highly resistant in order of prevalence to penicillin(98.7%), ampicillin(91.5%), streptomycin(90.3%), triple sulfa(83.1%), and trimethoprim/sulfamethoxazole(70.7%) while none of them were resistant to gentamicin, only 3.6% to colistin, chloramphenicol and kanamycin and 6.0% to tetracycline. The percentage of the organism resistant to bicozamycin, cephalothin and neomycin were 34.9%, 34.1% and 18.4%, respectively. A high prevalence of multiple drug resistance was observed and the 3 most common resistant patterns among 35 patterns noted were Am Pc Sm Sss Sxt(26.5%), Am Cf Pc Sm Sss Sxt(12.%) and Am Bm Pc Sm Sss Sxt(9.6%) patterns.
