[Specific immunoglobulins of different classes in brucellosis in human beings]

The paper is concerned with the results of studying the level of specific IgG, IgA and IgM in people with different forms of brucellosis. Immunoglobulins belonging to different classes were identified by means of IEA. Examination of 514 patients with different forms of brucellosis and 122 controls demonstrated the high specificity and sensitivity of IEA for detecting antibodies of different physiochemical nature. The use of IEA made it possible to establish definite regularities of the synthesis of specific IgG, IgA, IgM in people with brucellosis, which can be used for assessing the activity of the infectious process.
