The sensitivity of several group C arboviruses (Bunyaviridae) to human amnion interferon was compared to that of vesicular stomatitis virus (VSV) and Sindbis virus. In CPE inhibition assays, Apeu virus was the most sensitive of the group C arboviruses tested; it was significantly more inhibited than VSV, but was in the same range as Sindbis virus. In plaque reduction assays, the increasing order of sensitivity was Apeu, Marituba, VSV and Sindbis viruses. Single-cycle yields of VSV and ApΕu virus were reduced to the same extent with 1–10 interferon units; with 230 units, VSV growth was inhibited to a much greater extent (100-fold) than Apeu virus.
