This study was investigated resistance on disinfectants and antibiotics of Clostridium chauvoei isolated from dairy farm in Kyongbuk province. The results obtained were summarized as follows ; C chauvoei isolated from dairy farm were susceptible to norfloxacin, penicillin, tetracycline, erythromycin, enrofloxacin, bacitracin, tyrosine, cephalothin and cefazolin but resistant to gentamicin, kanamycin, sulfamethoxazole＋trimethoprim, amikacin, neomycin streptomycin, colistin. In effect on disinfectants, C chauvoei was inhibited completely to growth in mercuric bichloride ($HgCl_2$), harasol(sodium hypochloride 4-6%), long-life(high boiling tar acids et al), and phenol($C_6$$H_5$OH), but growth in all-stop(didecyl dimethyl ammonium chloride 10%), powercide(potassium monopersulphate 50% et al), antec vercon-s(triple salt 50% et al), and taego-51(6-alkyl-2.6-diaza-hexane-carbonic acid-1ㆍHCl et al). The effect of disinfectant was excellent in mercuric bichloride and harasol.
