The aim of this study was to determine the seroprevalence of Toxoplasma gondii in mares and stallionsin the province of Ankara. Sera from 168 clinically healthy horses were tested for the presence ofToxoplasma gondii antibodies using the Sabin Feldman dye test. Toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

European and North American strains of the parasite Toxoplasma gondii belong to three distinct clonal lineages, type I, type II, and type III, which differ in virulence. Understanding the basis of Toxoplasma strain differences and how secreted effectors work to achieve chronic infection is a major goal of current research. Here we show that type I and III infected macrophages, a cell type requi...

Infection with the protozoan parasite Toxoplasma gondii is characterized by asymptomatic latent infection in the central nervous system and skeletal muscle tissue in the majority of immunocompentent individuals. Life-threatening reactivation of the infection in immunocompromized patients originates from rupture of Toxoplasma cysts in the brain. While major progress has been made in our understa...

Latent toxoplasmosis is known to influence the morphology of infected persons and also increases the probability of the birth of male offspring in both humans and mice. All these traits can be related to the observed differences in the concentration of testosterone between Toxoplasma-infected and Toxoplasma-free subjects. However, it is not possible to decide, using the Toxoplasma-human model, ...

BACKGROUND The diagnosis of reactive arthritis is a challenging clinical problem in daily practice. Although there are many triggering infectious agents for reactive arthritis, Toxoplasmosis, a worldwide parasitic infection has not been reported. AIM We investigated the serologic evidence of Toxoplasma gondii ( T. gondii ) infection in patients with newly diagnosed reactive arthritis after si...

Toxoplasma gondii, an obligate intracellular protozoan parasite, is one of the most successful eukaryotic pathogens. It can infect virtually any warm-blooded animal, including humans, in whom it can cause serious disease. Its success is likely due to its ability to modulate host immune responses and host innate immune signaling pathways allowing it to establish a chronic infection with few symp...

The risk of Toxoplasma gondii infection in solid organ transplant recipients is well known but mainly after heart transplantation. We discuss a case of acute respiratory distress caused by Toxoplasma gondii on Day 32 after liver transplantation. The reported case, which is extremely rare, emphasizes how direct examination and Quantitative Polymerase Chain Reaction (QPCR) in broncholaveolar lava...

background: human toxoplasmosis is an important zoonotic infection worldwide which is caused by the intracellular parasite toxoplasma gondii (t.gondii). the aim of this study was to review briefly the general aspects of toxoplasma infection in   in iranian health system network. methods: we searched published toxoplasmosis related articles in english databases including science direct, pub med,...

results: of the 50 samples tested by the elisa method, 26 samples (52%) were positive for igg . no samples were positive for igm. of the 50 samples tested by the chemiluminescence method, 28 samples (56%) were positive for igg. no samples were positive for igm. conclusions: a significant relationship between the age of the youngest child and the infection rate was seen. no significant correlati...

The ability to discriminate between primary Toxoplasma gondii infection acquired in early pregnancy and infection that occurred prior to pregnancy was assessed by an enzyme immunoassay (EIA) to determine the avidity of toxoplasma-specific immunoglobulin G (IgG). The results were compared to those of the Platelia Toxo-IgM EIA and the dye test. The mean IgG avidity of 73 serum samples collected w...
