Antibody-induced movement of protozoan surface membrane antigens.

Direct and indirect immunofluorescence techniques were used to study the effects of host antibodies on surface membrane antigens of viable Leishmania parasites in vitro. Antisera to L. enriettii and L. tropica caused surface membrane antigens of these parasites to aggregate, move toward the poles of the parasite, and to eventually disappear. This sequence… CONTINUE READING
