Trypanosoma cruzi: Antibodies to a MAP-like protein in chronic chagas' disease cross-react with mammalian cytoskeleton

Trypanosoma cruzi λgtll library from epimastogote derived mRNA was screened with human chagasic sera or sera from chronically infected mice. Strong reactive recombinants were detected with both sera. Two recombinant clones were studied in more detail and shown to be composed of the same 114-bp repet...
