Surface antigenic change during differentiation of a parasitic protozoan, Leishmania mexicana: Identification by monoclonal antibodies. [PDF]

Proceedings of the National Academy of Sciences, 1982
The fusion of SP2/0 myeloma cells with spleen cells from mice immunized with Leishmania mexicana amazonensis promastigotes produced hybridoma clones. Indirect immunofluorescent antibody assay with live leishmanias showed that the monoclonal antibody 6H12 recognized only the antigens bound to the surface of L. mexicana amazonensis promastigotes. It also

Systemic and Cutaneous Mucus Antibody Responses of Channel Catfish Immunized against the Protozoan ParasiteIchthyophthirius multifiliis [PDF]

Clinical and Vaccine Immunology, 2003
ABSTRACTFish acquire protective immunity against the ciliated protozoan parasiteIchthyophthirius multifiliisfollowing sublethal infection or inoculation withI. multifiliisimmobilization antigens (i-antigens). In both cases, parasite-immobilizing antibodies have been identified in sera and mucosal secretions.

B-Cell Response during Protozoan Parasite Infections

Journal of Parasitology Research, 2012
In this review, we discuss how protozoan parasites alter immature and mature B cell compartment. B1 and marginal zone (MZ) B cells, considered innate like B cells, are activated during protozoan parasite infections, and they generate short lived plasma ...
