Body temperatures, virus shedding and transmission in pigs.
Nine Pigs were intranasally inoculated with 106 TCID50 of each virus. Five naïve pigs were maintained as a control group and were mock-inoculated with PBS. After 24 h, the inoculated animals were housed together with three contact pigs. Tissues from three pigs in each inoculated group were collected for virus detection at 3 and 5 dpi, respectively. (A) Rectal temperature of infected piglets was taken at fixed time-point daily from 0 to 9 dpi. (B,C) Viral titers in nasal washes of three infected or co-housed piglets from each group. Each bar represents the virus titer from an individual animal. The horizontal dashed line corresponds to the TCID50 assay detection limit. Data are presented as means ± SD of three pigs. *the value of Sw-41X(WT) was significantly different from Sw-61X (P < 0.05, ANOVA).
