Latency attenuation of the TMER4 mutant is dependent upon the route of inoculation. Parallel groups of mice were infected i.n. (A) or i.p. (B) with wild-type MHV68 (MHV68.βla) or MHV68 TMER4 mutant (MHV68.ΔmiR5.6), and a limiting dilution nested PCR for viral genome was performed on splenocytes exactly as described for Fig. 1.
