Characterization and Pathogenicity of the Novel Porcine Reproductive and Respiratory Syndrome Virus 1 Strain SL-01 in China

<div>Pathogenicity results in piglets. (a) Body temperature changes in piglets in each group after challenge. (b) Clinical scores of piglets after challenge throughout the experiment. (c–e) Viral load detection in the blood, oral swabs, and pharyngeal swabs. (f) PRRSV-specific antibody level in each group during the challenge study. (g) Survival rate of pigs in each group during the challenge study. Each bar represents the mean ± standard deviation in each group.
