Abstract
A total of 98 strains of Bordetella bronckiseptica isolated from pigs affected the infectious atrophic rhinitis(AR) during 1978 were surveyed for drug sensitivity to 26 chemotherapeutic agents, and minimum inhibitory concentration(MIC), incidence rate of resistant strain and resistant patern from the strains which were obtained from the different pig farm in Jeonnam province were examined. The results obtained are summarized as follows. 1. Most of the strains tested were resistant to Ampicillin (AB, PC), spiramycin(SPO, sulfa drugs (SD) (MIC:$400.0{{mu}g/ml}$) and streptomycin(SM) (MIC:$200.0{{mu}g/ml}$). Of the 75.0% of strains were also resistant to penicillin(PC) (MIC:$200.0{{mu}g/ml}$) and of the 14.3 of strains were inhibited to grow to tetracycline(TC), chlortetracycline(CTC), oxytetracyc-line(OTC), erythromycin(EM), tylosin(TS), leucomycin (LM) and chloramphenicol (CP) (MIC:$6.25{{mu}g/ml}$). On the other hand, most of the strains tested were inhibited to grow to kanamycin(KM), gentamycin(GM) neomycin(NM) (MIC:$25.0{{mu}g/ml}$) and to colistin(CL) (MIC:$12.5{{mu}g/ml}$). 2. Incidence rate of resistant strains to main chemotherapeutic agents was 100.0% of sulfa drugs, 96.4% of streptomycin, 85.7% of penicillin, tetracycline, chloramphenicol and erythromycin, 46.4% of gentamycin, 17.9% of colistin and 0.0% of kanamycin and nalidixic acid.
