| dc.description.abstract | Porcine epidemic diarrhea virus (PEDv) and porcine deltacoronavirus (PDCoV) have been a major challenge for the North American swine industries recently. As these viruses are transmitted via the fecal-oral route, their survival in the environment can impact the spread and re-occurrence of associated diseases. This study determined the viability of the viruses in the earthen manure storages (EMS) and in the soil under Manitoba climate. Two PEDv and PDCoV co-infected farms were monitored. PDCoV was monitored over the Fall and found to survive in the EMS for the whole period while maintaining a stable population. PEDv was monitored from Fall into Winter and Spring and found to survive –and potentially replicate– in the EMS for at least 9 months. Once the infected manure was surface applied on the land, PEDv were found in 95% of soil samples three weeks following land application, including the soils from off-band manure applied locations. | en_US |
