Seroprevalence of Toxoplasma gondii infection in zoo and domestic animals in Jiangxi Province, China

Parasite, 2017
Toxoplasma gondii is a zoonotic protozoan parasite that infects a wide range of warm-blooded animals throughout the world. In the present study, antibodies to T.

Prevalence and Toxoplasma gondii Genotypes Circulating in Five Wild Corvid Species from Romania

Pathogens
The apicomplexan parasite Toxoplasma gondii can potentially infect all warm-blooded animals, including birds, which, due to their high dispersal capabilities, are considered a significant candidate group of sentinel animals that reveal environmental ...

Antibodies Targeting a Conserved Surface Polysaccharide Are Protective Against a Wide Range of Microbial Pathogens Producing β-1–6-Linked Poly-N-Acetylglucosamine (PNAG)

Engineering
The β-1–6-linked poly-N-acetylglucosamine (PNAG) polymer is a conserved surface polysaccharide produced by many bacteria, fungi, and protozoan (and even filarial) parasites.

Social context influences Toxoplasma gondii and Trichinella spp. infection in Alberta free-roaming wild pigs (Sus scrofa).

PLoS ONE
The increasing spread of wild pigs across Canada is concerning due to their potential role as reservoirs for zoonotic diseases, including trichinosis and toxoplasmosis. Trichinosis is caused by the parasitic nematode Trichinella spp.

Antibodies to protozoan variable surface antigens induce antigenic variation

2022
Abstract The genomes of most protozoa encode families of variant surface antigens, whose mutually exclusive changes in expression allow parasitic microorganisms to evade the host immune response 1,2 .

ANTIBODY‐INDUCED MOVEMENT OF PROTOZOAN SURFACE MEMBRANE ANTIGENS*

Annals of the New York Academy of Sciences, 1975
Direct 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, 1986
The 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 ...

Induction of Tolerance to an Intracellular Protozoan (Toxoplasma Gondii) by Passively Administered Antibody

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 ...
