摘要: Eastern equine encephalitis (EEE) virus replication in rabbit kidney (RK) cells was inhibited by interferon (IF). Interferon protected against the virus-induced shutoff of host protein synthesis and partially suppressed EEE structural proteins infected cells. High doses (300–3000 units) labeling viral RNA interferon-treated RK as much 98 per cent, measured TCA precipitation following 10, 30 or 60 minute period. Sucrose gradient analysis confirmed that incorporation of3H-uridine into 23S 40S interferon, latter being slightly more sensitive. The logarithm surviving fraction each virus-specific event persisting cell a linear function IP dose over 1000-fold concentration range. relative sensitivities events were from highest to lowest: yield > EEE-induced CPE = synthesis.
