infection of untreated a/j animals and vehicle controls with mhv3 resulted in marked and reproducible activation of peritoneal macrophages , observed in vitro as resistance to mhv3-cytopathic effects 48 hr after rechallenge with the virus , whereas exposure to dieldrin resulted in apparent loss of the intrinsic capacity of cells to restrict replication of mhv3 and to protect them from cytolysis .
