Viral titers in organs of MHV-2-infected β2M(-/-) mice (A) compared to MHV-2-infected B6 mice (B). β2M(-/-) mice were infected IC with 5 × 103 PFU of virus and B6 mice were infected IC with 5 × 105 PFU of virus then sacrificed at various intervals postinfection; organs were aseptically removed and viral titers were determined by plaque assay.
