title: [Importance of Australia antigen in bronchopulmonary diseases].
abstract: Australia antigen (HB Ag) was determined by electroimmunodiffusion in 327 patients with various bronchopulmonary diseases admitted to the Clinic of Pneumophthisiology. Of the total cases investigated 19 (5.8%) presented a positive HB Ag titer. It is considered that the incidence of positive HB Ag cases in the Clinic does not reflect the frequency of the disease in the general population, bearing in mind the selection of the cases in the Clinic. Determination of the HB Ag is of importance for detecting active or latent infections with hepatitis virus type B, requiring follow up and isolation of the patients as well rigurous disinfection.
