title: [Comparative evaluation of the functional activity of different immunoglobulin classes in cholera].
abstract: The immunological activity of specific immunoglobulins in different forms of cholera infection was studied with the use of the indirect immunofluorescent method. The forms of cholera infection were shown to be related to the physico-chemical spectrum of antibodies: patients with the pronounced clinical symptoms of cholera produced serum IgM, including antigen -- antibody complex, more actively and in a greater amount; patients with faintly pronounced and asymptomatic infection produce highly active IgG. The competitive action of immunoglobulins of different classes in their simultaneous reaction with O antigen of Vibrio cholerae is shown. The mechanism of the competitive action of different immunoglobulin classes is supposed to play some role in the process of the sanation (with highly active IgM) or detoxication (with highly active IgG) of the organism.
