Abstract
|
|
|
|
The coronavirus porcine epidemic diarrhea virus (PEDV) infects the cells lining the small intestine of a pig and, causes porcine epidemic diarrhea (PED). Owing to its highly infectious nature, PEDV has a substantial economic burden, which results in significant morbidity and mortality in piglets. In this study, the virucidal efficacy of a powder disinfectant containing a phosphate compound against PEDV was investigated. Virucidal efficacy was assessed as the infectivity of PEDV toward Vero cells after exposure of the virus to the disinfectant. PEDV was exposed to the disinfectant in the presence of either hard water (HW) or an organic matter suspension (OM). In the HW condition, PEDV was inactivated by 4-fold dilution of the disinfectant. In the presence of OM, the disinfectant showed virucidal activity with a 2-fold dilution. As the disinfectant possessed virucidal activity against PEDV, it should be an effective reagent for limiting the spread of animal viral diseases.
