Mortality data for SCID/ICR mice inoculated with 5 × 105 PFU of SPYF-E, SPYF-EI-II, and SPYF-EIII viruses by the i.p. route. Experimental procedures were carried out as described in Materials and Methods. The mortality curves were constructed using data from three separate experiments for which similar survival times were recorded within groups of mice inoculated with the same viruses.
