Effect of Disinfectants of Quaternary Ammonium Compounds with Limewater Against Avian Influenza Virus and Bovine Enterovirus at Low Temperature and with Organic Matter Contamination

Abstract

Effects of a single disinfectant of didecyldimethylammonium chloride (DDAC) (single A) and a compound disinfectant (compound B) consisting of DDAC and phenolic compounds, with limewater or distilled water on avian influenza virus (AIV) and bovine enterovirus (BEV) were investigated at low temperature and with organic matter contamination. Both disinfectants showed a virucidal effect toward AIV. Using limewater increased these effects, but compound B showed higher effects than single A at low temperature and with organic matter contamination. Single A and compound B were effective against BEV with limewater, but not in the distilled water. These effects were significantly reduced at low temperature and with organic matter contamination, but compound B displayed virucidal effects against BEV. It was concluded that single A and compound B with limewater was more effective against AIV and BEV than with distilled water. And compound B showed more virucidal effects at low temperature and with organic matter contamination.
