The present study was conducted to investigate the isolation frequency, biochemical prop erties and antimicrobial susceptibility of B. bronchiseptica isolated from slaughtered pigs during the period from March to December, 1992. In Kyeonggi province. A serological survey for antibody of B. bronchiseptica in 200 slaughtered pigs was carried out by agglutination and tetrazolium reduction methods. The results were summarized as follows ; 1. From 80 slaughtered pigs, 27(33.8%) case were isolated and all isolate strains were resistant to Penicillin, Streptomycin, Chloramphenicol, Tetracycline and Ampicllin, while the majority of them were susceptible to Gentamicin, Cloxacin, Colistin, Neomycin, and Kanamycin. 2. Incidence of B. bronchiseptica antibody in 200 slaughtered pigs were measured by agglutination and tetrazolium reduction methods. Agglutination method was shown 38 (19%) of 200 with a titer of below 1：20 and 20(10%) of 200 with a titer of above 1：640. Tetrazolium reduction method was observed 33(16.5%) of 200 with a titer of below 1 : 20 and 32(15%) of 200 with a titer of above 1：640. 3. LSD analysis indicated that the difference of the responses between agglutination test and tetrazolium reduction test was not significant.
