Dogs infected with a pathogenic Trypanosoma cruzi isolate (Tc-O), or a non-pathogenic isolate (Tc-D) developed low antinuclear antibody titers throughout 240 days of infection. Dogs infected with Tc-O, but not Tc-D, produced anti-heart tissue antibodies (as measured by an ELISA) throughout infection. Antibody levels were highest immediately after the acute stage of infection (30 days post-inoculation--DPI) when myocardiocyte destruction was at its greatest. Antibody levels progressively declined by 100 DPI, and were almost undetectable by 240 DPI when Tc-O infected dogs developed dilated cardiomyopathy. On Western blots, the anti-heart tissue antibodies recognized an antigen with the same molecular weights (65 and 61 kDa M(r)) recognized by a monoclonal antibody against human beta-adrenoceptors. The results suggest that dogs produce antibodies against heart tissue antigens, possibly the beta-adrenoceptor, during infection with a pathogenic, but not a non-pathogenic, isolate of T. cruzi.
