Level of serum antibodies to mycobacterial antigens in healthy Czechs.
Levels of IgG antibodies to Mycobacterium bovis BCG and M. avium antigens were examined by enzyme-linked immunosorbent assay (ELISA) in samples of sera from 898 healthy adults aged greater than 40 years and 1170 children aged 1-6 years, selected at random in 10 districts of Czechoslovakia. The median antibody titre to M. bovis BCG in adults ranged from 1:28 to 1:161.7 and that in children from 0 to 1:50. The mean titres of M. avium antigen ranged from 1:2 to 1:21 in adults and from 0 to 1:8 in children.
