Immune complexes in chronic Chagas disease patients are formed by exovesicles from Trypanosoma cruzi carrying the conserved MASP N-terminal region [PDF]

, 2017
The exovesicles (EVs) are involved in pathologic host-parasite immune associations and have been recently used as biomarkers for diagnosis of infectious diseases.

Polyfunctional T cell responses in children in early stages of chronic Trypanosoma cruzi infection contrast with monofunctional responses of long-term infected adults [PDF]

, 2013
Background: Adults with chronic Trypanosoma cruzi exhibit a poorly functional T cell compartment, characterized by monofunctional (IFN-γ-only secreting) parasite-specific T cells and increased levels of terminally differentiated T cells.

Molecular characteristics of an immobilization antigen gene of the fish-parasitic protozoanIchthyophthirius multifiliisstrain ARS-6

Aquaculture Research, 2009
AbstractIchthyophthirius multi¢liis(Ich), a ciliated protozoanparasite of ¢sh, expresses surface antigens (i-anti-gens), which react with host antibodies that renderthemimmobile.Thenucleotidesequenceofani-anti-gen gene of I. multi¢liis strain ARS-6 was deduced.The predicted protein of 47493Da is comprised of460 amino acids (aa’s) arranged into ¢ve ...

Effects of drinking-water filtration on Cryptosporidium Seroepidemiology, Scotland [PDF]

, 2014
Continuous exposure to low levels of Cryptosporidium oocysts is associated with production of protective antibodies. We investigated prevalence of antibodies against the 27-kDa Cryptosporidium oocyst antigen among blood donors in 2 areas of Scotland ...

Bovine cytotoxic T cell clones which recognize lymphoblasts infected with two antigenically different stocks of the protozoan parasite Theileria parva

European Journal of Immunology, 1987
AbstractThe Muguga and Marikebuni stocks of Theileria parva differ on the basis of cross‐protection and in their schizont antigen profile determined with a panel of parasitespecific monoclonal antibodies. The phenotype and specificity of six cytotoxic T cell clones generated from an animal immunized against T. parva (Marikebuni) were investigated.
