PEDV titers in the enteric tract of animals vaccinated and challenged with virulent PEDV. Four days after the challenge with a virulent PEDV strain, jejunum samples were collected from three piglets per group. Virus presence in these samples was analyzed by titration in Vero cells (A) or by RT-qPCR (B). In addition, PEDV challenge virus shedding in fecal samples was evaluated at different days after challenge, by RT-qPCR (C). Animals vaccinated with rTGEV-RS-SPEDV virus (red); pigs vaccinated with the virulent US PEDV-NVSL strain (green); non-vaccinated and challenged animals (black). Error bars represent the standard deviation for each value.
