Abstract A mouse monoclonal antibody TCF87, prepared previously, was reactive with Trypanosoma cruzi-specific Mr 25000 antigen regardless of strain. The Mr 25000 antigen was recognized by all sera from chagasic patients living in different areas of South America, when examined by Western immunoblotting analysis. Although many antigens of T. cruzi epimastigotes were also recognized by sera from patients with leishmaniasis, the Mr 25000 antigen of T. cruzi did not react with leishmaniasic sera. These results indicate that Mr 25000 antigen recognized by TCF87 is valuable as a diagnostic antigen for Chagas' disease. When a competition enzyme-linked immunosorbent assay using TCF87 was carried out, all sera from Chagas' disease patients showed positive inhibition. By contrast, all patients with leishmaniasis or other parasitic diseases were scored as seronegative. The present study suggests that competition enzyme-linked immunosorbent assay using monoclonal antibody against the Mr 25000 antigen of T. cruzi will be useful for serodiagnosis of Chagas' disease in areas where leishmaniasis is co-endemic.
