Method for isolating a novel viral agent and the antigen associated therewith, viral agent and antigen obtained by this method and method for detecting the said antigen using a suitable immunological reagent

摘要

Novel purified viral agent implicated in both epidemic and sporadic non-A, non-B viral hepatitis, defined by the distribution profile of its antigenic activity, which contains at least one band with a density of 1.29-1.32 g/cm3 and/or at least one band with a density of 1.17-1.19 g/cm3, and the antigen associated with this viral agent. Method for isolating the said viral agent and the antigen associated therewith. Method for detecting a non-A, non-B antigen present in the faeces of patients suffering from non-A, non-B viral hepatitis.
