A gene sequence encoding an immunodominant protein with a repetitive epitope from the protozoan Trypanosoma cruzi, the causative agent of Chagas disease, was cloned and expressed. The identified 10-amino acid repeat is present within a high-molecular-weight trypomastigote antigen that appears specific to and conserved among T. cruzi isolates. More importantly, greater than 95% of T. cruzi infection sera, including both chronic and acute Chagas disease, contained elevated levels of antibody to a ...[more]
