B-Cell Response during Protozoan Parasite Infections [PDF]

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 ...

Serological evidence of Toxoplasma gondii infection in Melanosuchus niger (Spix, 1825) and Caimam crocodilus (Linnaeus, 1758)

International Journal for Parasitology: Parasites and Wildlife, 2020
Toxoplasma gondii is a protozoan with worldwide prevalence, known to affect a large variety of warm-blooded hosts. However, its ability to induce long-lasting infections in cold-blooded animals remains unclear.

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

High-resolution genotyping and mapping of recombination and gene conversion in the protozoan Theileria parva using whole genome sequencing [PDF]

, 2012
BACKGROUND: Theileria parva is a tick-borne protozoan parasite, which causes East Coast Fever, a disease of cattle in sub-Saharan Africa. Like Plasmodium falciparum, the parasite undergoes a transient diploid life-cycle stage in the gut of the arthropod ...
