Cell surface analysis of trypanosomes of the subgenus Schizotrypanum isolated from bats.
Two stocks (M5, M29) of trypanosomes of the subgenus Schizotrypanum were isolated from the bat Phyllostomus hastatus and analyzed for cell electrophoretic mobility (EPM) and lectin binding surface sites. Epimastigotes from the M5 and M29 stocks presented a mean EPM of around -0.57 and -0.56 microns. s-1.V-1.cm respectively. Differences in the agglutination profiles were detected between epimastigotes or trypomastigotes from the two parasite populations using lectins with specificity for D-GlcNAc, D-GalNAc, D-Gal and D-Man as probe. Major variation was observed between epimastigote forms. Additionally, the D-GlcNAc binding lectins WGA and BS II strongly interacted with the trypomastigote from both M5 and M29 stocks; this fact is evidence that these trypanosomes are distinct from Trypanosoma (Schizotrypanum) cruzi.
