A total of 36 sows from three different swine breeding farms located in the Mid-Eastern part of the US, having a clear PEDV infection history (uninfected, 1 month or 6 months post-infected) were selected, and six sows each from primiparous and multiparous groups were transported to a slaughter plant in Ohio. Clinical samples such as blood (plasma), oral fluid, and feces, and tissues of ileum, mesenteric lymph nodes, and spleen were collected on the day of necropsy.
