title: Inactivation of non-A, non-B virus infectivity by a beta propiolactone/ultraviolet irradiation treatment and Aerosil adsorption procedure used for preparation of a stabilized human serum.
abstract: Inoculation of chimpanzees revealed that starting material for the preparation of a pooled stabilized human serum preparation was contaminated with non-A, non-B hepatitis virus(es). This material was subjected to beta-propiolactone/ultraviolet irradiation treatment and adsorption with an insolubilized silicic acid under conditions employed for sterilization of the final product (Biseko, Biotest). The treated material did not transmit hepatitis to 2 inoculated chimpanzees. These animals were subsequently found to be susceptible to non-A, non-B infection by challenge with the untreated material. These findings demonstrate a non-A, non-B type hepatitis virus to be susceptible to inactivation by the methods employed for sterilization of this stabilized human serum preparation.
