[Study of the specificity of various classes of immunoglobulins (IgM and IgG) v techenie ornitoznoĭ infektsii].

Studies of the specificity of immunoglobulins of different classes in the course of both experimental and natural orinthosis infection showed IgG antibody to possess a wide spectrum of activity: group-, species- and strain-specific, but specificity to group antigenic components was predominant. IgM antibodies were species-specific, however, population of gammaM-immunoglobulins of animal sera in approximately 7 and 14 days after infection antibody suggested a method for the study of the antigenic structure of the agents of the genus Chlamydia.
