Abstract

Highly pathogenic avian influenza virus (HPAIV) is already panzootic in poultry and caused a considerable economic loss in poultry industry. In addition, HPAIV continues to cross species barriers to infect humans and other mammals, often with fatal outcomes. In this study, the virucidal efficacy of Citra-$Kill^{(R)}$ composed to quaternary ammonium chloride and citric acid was investigated against avian influenza H9N2 virus (AIV). A virucidal efficacy was determined with the viability of AIV contacted with the disinfectant in the allantoic membrane of chicken embryos. Citra-$Kill^{(R)}$ and AIV was reacted on the distilled water (DW), hard water (HW) or organic matter suspension (OM) condition. On DW condition, AIV was inactivated with 2,000 fold dilutions of Citra-$Kill^{(R)}$. When the antiviral effect on HW condition was evaluated, the antiviral activity of the disinfectant showed on 1,500 fold dilutions against AIV. With the investigation of the antiviral effect of the disinfectant on OM condition, AIV was inactivated on 500 fold dilutions of Citra-$Kill^{(R)}$. As Citra-$Kill^{(R)}$ possesses virucidal efficacy against AIV, the disinfectant solution can be used to limit the spread of animal viral diseases.

본 연구에서는 4급 암모늄에 속하는 quaternary ammonium chloride와 구연산의 합제인 Citra-$Kill^{(R)}$의 조류인플루엔자에 대한 살바이러스 효과를 확인하기 위해 국립수의과학검역원의 소독제 효력시험 중 바이러스 소독제 효력시험에 따라 수행하였다. 소독제와 조류인플루엔자바이러스를 증류수, 경수, 그리고 유기물 조건에서 반응시킨 후, 중화액을 이용하여 중화시킨 다음, 중화된 용액 0.2 ml를 10일령의 계태아 요막에 주입하여 5일 동안 배양시킨 다음, 요막액을 채취하여 바이러스의 생존여부를 혈구응집반응을 통해 확인하여 소독제의 효력배수를 결정하였다. 본 연구의 결과, Citra-$Kill^{(R)}$은 증류수, 경수, 그리고 유기물 조건에서 각각 2,000, 1,500, 그리고 500배에서 조류인플루엔자바이러스를 불활성화시켜, 조류인플루엔자에 대해 뛰어난 소독효과를 갖고 있는 것이 확인되었다. 따라서 향후, 야외적용시험을 통해 실제적용에 따른 효과를 확인할 필요가 있을 것으로 사료된다.
