Virulence of rTGEV-SPEDV viruses in suckling piglets. Five-day-old piglets were orally inoculated with 10⁶ TCID₅₀/piglet. Animals were mock infected (mock, black) or infected with rTGEV-SPEDV (blue) or rTGEV-RS-SPEDV (red) viruses. Clinical signs were observed daily. Weight loss (A) and survival (B) are represented. The values are the mean from nine independent animals. (C) Virus load in feces was evaluated by RT-qPCR. Error bars represent the standard deviation for each value; p values, * <0.05, ** <0.01, *** <0.001.
