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.

Use of Hybridoma Antibodies and Recombinant DNA Technology in Protozoan Vaccine Development
Avian Diseases, 1986The use of hybridoma antibodies developed against the sporozoite stage of avian coccidia, coupled with genetic-engineering techniques, has made it possible to begin bird-immunization studies utilizing an Escherichia coli-elicited coccidial protein. The coccidia are currently controlled in the poultry industry by use of anticoccidial compounds, but it ...

The Journal of Immunology, 1974
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 ...

Journal of Immunological Methods, 1986
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.

American Journal of Veterinary Research, 1986
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 ...

Naturally occurring antibodies that react with protozoan parasites
Parasitology Today, 1993In this paper, Eiji Konishi reviews general features of naturally occurring (natural) antibodies that react with protozoan parasites. Several functions of natural antibodies have been identified in relation to their multireactivity, but reports on protozoan infection have dealt mainly with the role of natural antibodies in the innate immunity of the ...

Cellular Immunology, 1984
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.

Infection and Immunity, 1996
Fish acquire immunity against the ciliated protozoan parasite Ichthyophthirius multifiliis following sublethal infection. The immune response includes the elaboration of humoral antibodies against a class of abundant surface membrane proteins referred to as immobilization antigens (i-antigens).

Journal of Fish Diseases, 2008
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.
