[A hitherto unknown reaction pattern in vertebrate cells (RiV). 2. The protective effect of RiV particle preparations
Abstract:
Further observations concerning the previously described RiV-particles are reported. They were isolated from a diploid cell line of bovine origin, embryonal duck fibroblasts and BHK-21 cells. A protective effect against foot-and-mouth-disease virus in guinea pigs could be observed following inoculation with the RiV-preparation of bovine origin. All 3 preparations isolated from the 3 cell lines showed immunologic cross reactions.
