title: [Use of the indirect hemagglutination reaction in studying ornithosis infection. III. The diagnostic value of the IHR with an ornithosis erythocytic diagnosticum].
abstract: In both experimental and clinical conditions the passive hemagglutination test (PHAT with the use of an ornithosis erythrocytic diagnostic preparation was found to be sufficiently sensitive and specific as compared with the complement fixation test (CFT), a routine testing method. The study of the dynamics of immune response in infected animals and ornithosis patients allowed to regard the PHAT as a comparatively early method of serological analysis. Hemagglutinins were also found to circulate in the patients' blood sera only for a short time (on the average for 1 1/2--2 months). The CFT and the PHAT with erythrocytic diagnostic preparation, used in combination, will make it possible not only to diagnose ornithosis in patient more effectively, but also to differentiate between the cases of infection and anamnestic reaction.20
