- Texas and Oklahoma institute new CVI requirements for non-commercial pigs entering the state.
- The Ohio Department of Agriculture announced the finding of a new coronavirus from fecal samples collected at four swine farms in Ohio. The clinical signs are similar to PED and TGE. One of the four farms tested PCR negative to PED and TGE but positive for the new virus, designated Swine DeltaCoronavirus (SDCV). Both PED and SDCV were detected in the other three farms.
- In response to on-going concerns about the possible role feed and/or feed ingredients may play in the transmission of PED virus, the swine nutritionists at Kansas State University are describing the steps some producers are taking to reduce their risk of PED virus being introduced through feed ingredients. They are also offering alternative nursery diet options minimizing or eliminating the use of porcine-derived feed ingredients.
- There have been multiple reports of PCR positive feed samples associated with PED outbreaks. To date, none of these feed samples have been found to be infective. A recent study at ISU, however, was able to experimentally infect susceptible pigs following gavage using negative feed spiked with PED virus. The feed industry and renderers responded to speculation about their products and possible PED contamination and transmission. Both groups lauded the safety of their processes. The feed industry pointed to the lack of an official protocol for validating the virus status of a feed sample. Questions have been raised regarding the safety of spray-dried plasma and similar porcine-derived products. Both the feed industry and the suppliers of the processed blood products have described the controls in place to ensure the safety of porcine-derived ingredients.
- As of late February 12, 2014, Canada is reporting at least 13 confirmed cases all located in Ontario. Nine farrow-to-finish and four wean-to-finish.
- Zoetis Inc. has announced a research partnership with Iowa State University (ISU) to identify and test a vaccine candidate to help control porcine epidemic diarrhea virus (PEDv) in the United States.
- Unfortunately, the New Case Report was unavailable at press time. It will be posted on the AASV website as soon as we receive it.
