Crithidia oncopelti

Surface membranes of symbiote-containing and -free strains of Crithidia oncopelti (a parasitic trypanosomatid protozoan) possess different capacities to bind lectins, the symbiote-free strain being more readily agglutinated with concanavalin A. Immunofluorescence studies, after in situ fixation, have shown... 

Glycosphingolipids with similar structures are found in Crithidia spp, which are considered to be lower trypanosomatids as their habitat is in invertebrate and since they do not have a cycle involving vertebrates (39). Neutral glycosphingolipids were isolated and characterized in Crithidia luciliae, C.oncopelti and C.guilhermei (40). The major glycolipids of the three species of Crithidia detected by HPTLC chromatography contain...
