Neuroinvasiveness of YF/JE virusesa

Virus % Mortality (no. dead/no. tested)b Strain
YF/JE-S 0 (0/4) ICR
YF/JE-N 0 (0/13) ICR
20 (3/15) C57BL/6
JE-N 100 (12/12) ICR
100 (11/11) C57BL/6
a

YF/JE-S, YF/JE-N, or JE-N was inoculated at 6 log10 PFU into 3-week-old mice by the intraperitoneal route. 

b

For both ICR and C57BL/6 mice, the difference in mortality of YF/JE-N versus JE-N was significant (P < 0.005, by χ2 analysis of the proportion of survivors).
