title: [Prevalence of Helicobacter pylori CagA-producing strains within families].
abstract: During prophylactic examination of blood sera taken from the members of 59 families by the enzyme immunoassay, antibodies to H. pylori and CagA protein were determined. As shown in this study, the children of non-infected mothers proved to be infected in 6.3% of cases and the children of infected mothers, in 72.1% of cases (p < 0.001). The children of non-infected fathers were H. pylori-positive in 71.4% and those of infected fathers, in 58.4% of cases. The CagA status was found to coincide in mothers and their children (p = 0.01), but not in fathers and their children. These data indicate that children acquire H. pylori infection from the members of their family, mainly from their mothers.
