^aBN-Brown Norway and F344-Fischer rats (immunocompetent strains, n=11/group) and Hsd:RH-Fox1rnu and NTac:NIH-Whn nude rats (immunocompromised stocks, n=10/group) were inoculated by oral gavage with 2.5 × 106 PFU RTV1. Sham inoculated rats (n=6 per group) were inoculated with uninfected BHK cell lysates by oral gavage.

^bNumber of rats infected/number of rats inoculated with RTV.

^cRepresents mean number of viral copies per mg of feces from rats actively shedding virus.

^dValues from rats shedding the lowest and highest number of viral copies within groups.
