title: [Radioimmunological survey of serological markers of viral hepatitis].
abstract: 230 serum samples of HBsAg carriers have been investigated for the presence of the combination HBeAg/anti-HBe as an index infectivity: an infectivity titre of 5,65% has been found for HBeAg and a positivity titre of 83,04% for anti-HBe antibody. In the institutionalized patients of an isolated community the positive titre of HBeAg resulted 28,57% whilst in the relevant health care staff the positivity titre was the same as detected for the carriers mentioned above. In a episode of viral hepatitis A in a child community a serological survey for IgM anti-HAV revealed 8 asymptomatic positive individuals referable to exposure to A type virus: it proves the utility of the individuation of IgM anti-HAV for an early diagnosis of the viral infection.
