In mice treated with ordinarily sublethal doses of parathion 2 to 5 days postinfection with murine cytomegalovirus (MCMV) 50 to 100% mortality was observed. These mortalities appeared to be due to a decrease in the ability of infected mice to detoxify parathion. Pentobarbital-induced sleeping time was also enhanced 3 and 6 days postinfection and cytochrome P-450 concentrations were markedly depressed in mice tested 3 days after infection. MCMV-induced effects on sensitivity to parathion and pentobarbital did not appear to be directly attributable to liver infection since concentrations of virus in the liver persisted at maximum concentrations well beyond the time when sensitivity to these compounds returned to normal. The time frame during which enhanced sensitivity to parathion and pentobarbital was observed suggests that this sensitivity may have been caused by viral-induced interferon-mediated depression of cytochrome P-450. |
