ABSTRACT

The lipopeptidophosphoglycan (LPPG) component isolated from epimastigote forms of Trypanosoma cruzi has antigenic properties. Using a rabbit antiserum aginst LPPG, specific for ß-D-galactofuranosyl residues (1-3)-linked to alfa-Dmannopyranose, we identified, by indirect immunofluorescence, the presence of epitopes containing ß-D-galactofuranosyl structures on the cell membrane of epimastigote, amastigote and trypomastigote forms of the parasite. The results demonstrade that all developmental stages of T. cruzi contain similar antigenic determinants on their cell body and flagellar membrane
