Abstract
Subtyping in various groups of persons positive for hepatitis B surface antigen gave the following results: Among asymptomatic blood donors (healthy carriers) subtypead was found in 20, subtypeay in 24. Among symptomatic patients with acute hepatitis Bad was found in 25,ay in 29. Among patients of an institution for the mentally retardedad was found in 9,ay in 23. Among patients of a geriatric institutionay was found in 9; among medical personnel of the same geriatric institutionay was found in 3 persons. Among symphilis patientsad was found in 6,ay in 29; and in patients of a dialysis centreay was found in 6. These data show that neither subtype is really dominant in Belgium. Die Bestimmung der Subtypen an verschiedenen Personengruppen mit positivem Hepatitis-B-Oberflächenantigen erbrachte folgende Ergebnisse: Unter asymptomatischen Blutspendern (gesunde Träger) wurde der Subtypad bei 20, der Subtypay bei 24 festgestellt. In einer Gruppe symptomatischer Patienten mit akuter Hepatitis B wurdead bei 25 unday bei 29 ermittelt. Patienten einer Anstalt für geistig Behinderte wiesenad in 9 Fällen unday in 23 Fällen auf. Unter den Patienten einer geriatrischen Klinik wurdeay bei 9 Personen festgestellt, desgleichen bei 3 Personen des ärztlichen Personal derselben geriatrischen Klinik. Bei syphilitischen Patienten wurdead in 6 Fällen unday in 29 Fällen ermittelt. Unter den Patienten eines Dialysezentrums fand sichay in 6 Fällen. Diese Ergebnisse zeigen, daß keiner der beiden Subtypen in Belgien wirlich dominiert.Keywords
