The present study was attempted to compare the Neospora caninum (N. caninum) antigenic bands recognized by different bovine immunoglobulin classes. A total 10, 5, 2, and 6 antigenic bands were exhibited on immunoblot profiles against bovine IgM, IgE, IgA, and IgG, respectively. A 46 kDa band was probed as a common antigenic band except IgA; 69 kDa band was bovine IgM and IgE; 33, 37, 55, and 79 kDa bands were bovine IgM and IgG; 72 kDa band was found IgM and IgA profiles. Based on the analysis, it appeared that different immunoglobulin classes recognizing different antigenic molecules were cooperating to cope with neosporosis.
