[Use of the immunofluorescent microagglutination reaction for the intrageneric differentiation of the immune response in chlamydiosis].

The possibility of using, on principle, the immunofluorescent microagglutination test with Chlamydia fluorescent corpuscular antigen for the strain-specific differentiation of immune response induced by the causative agents of ornithosis (strain B), enzootic abortus ovis (strain EAE) and lymphogranuloma venereum (strain LV) has been experimentally demonstrated. The calculation of indices, characterizing the specificity of differences between the systems under comparison, by the method of S. Frasser and D. Berman (1965) has confirmed the significance of such differentiation.
