The surface of freshly recovered mature adult parasites was covered with an irregular but often rather intensive mouse antibody containing matrix, which probably represents a layer of mouse antibody/parasite antigen complexes. The complexes were lost after in vitro culturing of the parasites for 24 h, but incubation of the in vitro-maintained antibody-negative adult parasites with immune mouse serum led to reformation of a similar but less intensive cover with immune complexes.
