In 1973, immune electron microscopy led to the identification of virus particlesin extracts of feces (Fig. 70-2) duringthe early acute phase of illness, providing the long-awaited lead to furtherstudies of this infection. Availability of viral antigen permitted, in turn,identification of specific antibody, development of serologic tests forhepatitis A, and determination of susceptibility to infection in human andnonhuman primates. Human hepatitis A has been transmitted to certain species ofnon-human primates shown to be free of homologous antibody, thereby providing amodel for experimental infection and, initially, also a source of reagents. 2ff7e9595c
