Virological analyses of WMHV infection of wood mice. Wood mice (three per time point) were infected intranasally with 4×105 p.f.u. MuHV4 or WMHV. Results are shown as means±sd; the asterisk represents a statistically significant difference between species (P<0.05). (a) Infectious virus recovered from the lung at 7 and 14 days p.i. Titres were measured by plaque assay on NIH3T3 cells. (b) Mean leukocyte numbers per spleen. (c) Infective centre (i.c.) assay of the level of latency in splenocytes. Infectious virus titres in the samples were analysed in parallel and were subtracted from the number of total infectious centres.
