Orthodichlorobenzene cresol complex formulation (trade name: Tanabezole, Osaka Kasei Co., Ltd., Osaka) has been recognized not only for killing larva of flies but also for its antimicrobial and anti-parasitic properties. In this study, we investigated the anti-avian influenza virus properties of this agent in ovo. It showed strong anti-avian influenza virus properties. When this agent was diluted at 1 : 100 to 200 and put into contact with avian influenza virus for 10 minutes at room temperature (37 ºC), no surviving virus was detected. Although its anti-viral properties weakened somewhat at 4 ºC, this agent showed strong anti-avian influenza virus properties when it was put into contact with the virus for 60 minutes at same temperature. The presence of organic matter in virus fluid did not affect the anti-avian influenza virus properties. It was concluded that this agent is a useful disinfectant in the poultry industry.
