Resistance on disinfectants of Clostridium chauvoei isolated from Kyongbuk province

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.
