[Changes in the indices of the B-immunity system in patients with intestinal nematodiases after treatment].

A decrease in the titers of antibodies to opportunistic bacteria has been observed in 100 patients suffering from ascariasis, trichocephaliasis and mixed invasion (ascariasis and trichocephaliasis). The immune suppression was higher in patients with mixed invasion. Medamine treatment enhances the suppression of antibody production. Changes in humoral immunity parameters are due to the effect of helminthic antigens and the composition of Escherichia in the large intestine of the affected subjects.
