In this study, we demonstrated that membrane immunofluorescence (MIF) with canine erythrocytes is a much more sensitive diagnostic technique compared with the Coombs test to detect auto-antibodies on RBC. We also demonstrate how the evaluation of the MIF test can be made more precisely which results in a more clear interpretation. Till nowadays the Evans syndrome (combined thrombocytopenia and anemia) is not very well diagnosed in dogs. Only a few studies with low animal numbers tested auto-antibodies on RBC and thrombocytes. Here we describe the frequency of Evans syndrome based on the evaluation of a large data set with 557 dogs. The novelty of the thesis also lies in making a research of the amount of CICs in sera of AIHA/AITP patients is described as well as the cytotoxic potential of patient’s sera for canine leucocytes. These new aspects of diagnosis (AIHA) and pathogenesis (AIHA/AITP) are not only relevant for dogs but also for humans and can be used for better differential diagnosis in medicine. The new findings with respect to circulating immune complexes and cytotoxicity are also offer new therapeutic concepts. Besides, the study has resulted in the characterization of monoclonal antibodies which allow for the detection of so far undetectable canine differentiation antigens (CD molecules) on canine erythrocytes (CD235) and thrombocytes (CD42a). The identified mAbs are useful in the identification of relevant target structures for autoantibodies on these cells.
