Viral proteins derived from an enterically transmitted non-A/non-B viral hepatitis agent (HEV) are disclosed. In one embodiment, the protein is immunologically reactive with antibodies present in individuals infected with the viral hepatitis agent. This protein is useful in a diagnostic method for detecting infection by the enterically transmitted agent. Specific epitopes have been identified that are reactive with sera of individual infected with different strains of HEV. Also disclosed are DNA probes derived from a cloned sequence of the viral agent. These probes are useful for identifying and sequencing the entire viral agent and for assaying the presence of the viral agent in an infected sample, by using probe-specific amplification of virus-derived DNA fragments.

As proteínas viral derivadas de um agente viral enterically transmitido do hepatitis de non-A/non-B (HEV) são divulgadas. Em uma incorporação, a proteína é immunologically reactive com os antibodies atuais nos indivíduos infected com o agente viral do hepatitis. Esta proteína é útil em um método diagnóstico para detectar a infecção pelo agente enterically transmitido. Os epitopes específicos foram identificados que são reactive com os sera do indivíduo infected com tensões diferentes de HEV. São divulgadas também as pontas de prova do DNA derivadas de uma seqüência cloned do agente viral. Estas pontas de prova são úteis para identificar e arranjar em seqüência o agente viral inteiro e para assaying a presença do agente viral em uma amostra infected, usando o amplification sond-específico de fragmentos vírus-derivados do DNA.
