Three antigen types were produced by ultra-sound treatment of the initial material (Anaplasma marginale Theiler infected blood) and its subsequent sedimentional centrifugation from 10 000 to 100 000 G. Their specificity and susceptibility to the Reaction Complement Binding (RCB) and to the capillary agglutination (CA) serological tests was comparatively checked up. Antigens A and B were very active in RCB, while antigen B--in the CA reaction. By these qualities they meet the requirements and are suitable for the practical need of discovering animals-carriers of anaplasmosis.
