Mice were infected with cell culture grown virus stocks.

GMT–geometric mean titer.

N–total number of animals taken for experiment.

^*–the number of animals in which blood (brain, spleen) the virus was detected.

^**–in 10% tissue (brain, spleen) suspension.

“–” not detected.

Panel b–Real Time PCR sensitivity 1000 RNAs/sample.

Panel c–Real Time PCR sensitivity 3000 RNAs/sample.
