The lymphocytic choriomeningitis virus (LCMV) isolates Docile (D) and Aggressive (A) of Pfau et al. were studied in various strains of mice. Disease susceptibility, assessed as mortality and time to death to LCMV-D or -A varied greatly amongst mouse strains, and all four possible susceptibility patterns were observed: susceptibility to both (e.g. SWR/J), resistance to both (e.g. DBA/2), susceptibility to A but resistance to D (C57BL/6), or vice versa (CBA/J). Irrespective of the virus isolate or the mouse strain tested, susceptibility correlated with both early and high cytotoxic T cell activity found in spleens or leptomeningeal infiltrates, and with early and high primary footpad swelling reaction after local infection. C57BL/6 mice infected with A or SWR/J infected with A or with D showed, in both test systems, early and high activities; in contrast, DBA/2 mice infected with either D or A, and C57BL/6 infected with D showed no or only slow and low responses in both tests. Early and high LCMV-specific cytotoxic T cell activity, and the rapidity and extent of the primary footpad reaction directly correlated with susceptibility to LCM and all were dominantly regulated by H-2D.
Susceptibility to lymphocytic choriomeningitis virus isolates correlates directly with early and high cytotoxic T cell activity, as well as with footpad swelling reaction, and all three are regulated by H-2D.
