ANTIBODY‐INDUCED MOVEMENT OF PROTOZOAN SURFACE MEMBRANE ANTIGENS*
Annals of the New York Academy of Sciences, 1975Direct 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.

Abstract The humoral antibody response to infection with the intracellular protozoan Toxoplasma gondii was suppressed in adult mice that had been injected with antiserum formed against the same parasite. A small proportion of the mice developed a state of tolerance to Toxoplasma, demonstrable by the absence of Toxoplasma antibody in ...

A sensitive immunoassay for detecting antibodies to the protozoan parasite of poultry Eimeria tenella, has been developed. Microspheres coated with parasite antigen are reacted with antibody-containing chicken serum followed by a fluorescent labeled second antibody and analyzed by flow cytometry.

High-affinity allergen-specific human antibodies cloned from single IgE B cell transcriptomes
Science, 2018IgE B cells unmasked Immunoglobulin E (IgE) antibodies play a central role in immune responses against helminth and protozoan parasites; however, they also contribute to allergies. IgE antibodies (and the B cells generating them) are rare and thus poorly

Glycosylphosphatidylinositol anchored proteins (GPI-APs) are natural conjugates in the plasma membrane of eukaryotic cells that result from the attachment of a glycolipid to the C-terminus of many proteins.

SUMMARY An initial panel of 34 hybridomas, each secreting antibodies reactive with an infective theront stage of an Ichthyophthirius multifiliis isolate, was produced. Three of these cell lines, each producing immunoglobulin M class antibodies, were cloned by limiting dilution and were expanded as ascites-producing tumors in syngeneic mice.

A broad spectrum monoclonal antibody to alpha-tubulin does not recognize all protozoan tubulins
Protoplasma, 1985Monoclonal antibodies able to recognize single antigenic determinants are a powerful tool for the study of immunological heterogeneity of antigens. In this paper we have used a monoclonal antibody against the α-subunit of pig brain tubulin (TU-01) to investigate the immunoreactivity of tubulins from mammals, avians, amphibia, echinodermata ...

To understand murine host responses to extracellular protozoa, the capacity of peritoneal macrophages to exhibit cytotoxicity for [3H]thymidine-labeled Giardia lamblia trophozoites was investigated. Resident peritoneal macrophages from C3H/HeN mice expressed spontaneous cytotoxicity for G.

Current and emerging tools for detecting protozoan cysts and oocysts in water
, 2019Water-borne protozoan parasites like Cryptosporidium, Giardia, Entamoeba and Toxoplasma are responsible for 1.7 billion cases of diarrhea globally, representing the second most frequent reason for mortality among children under five.

AbstractThe efficacy of a vaccine against the fish pathogen Philasterides dicentrarchi was evaluated in turbot by measuring the production of specific antibodies and duration of protection. Four groups of turbot were vaccinated twice, on days 0 and 30, with phosphate‐buffered saline, mineral oil adjuvant, antigen or antigen plus adjuvant.
