국문 초록

This study evaluated the bactericidal efficacy of a disinfectant containing chlorine dioxide as its main ingredient against Paenibacillus larvae (P. larvae) that is the causative agent of American foulbrood. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to P. larvae for 30 min at 4°C. The disinfectant and test bacterium were diluted with low and high organic matter (OM) suspension according to treatment condition. On low and high OM conditions, the bactericidal activity of the disinfectant against P. larvae was 2.5 and 1.25 fold dilution, respectively. The recommended dilution time of the disinfectant in low and high OM was 2.0 and 1.0 fold dilution, respectively. As the disinfectant possesses bactericidal efficacy against P. larvae, the disinfectant can be used to prevent American foulbrood in larvae of honeybees.
