An effect of parasites on host behaviour was tested on the toxoplasma-human model. Three hundred and thirty-eight (338) people were assessed with Cattell's personality questionnaire and then tested for Toxoplasma gondii infection with a delayed type hypersensitivity test for Toxoplasma. A highly significant correlation between chronic toxoplasmosis and two personality factors (G-Low Superego St...

Background: Congenital toxoplasmosis results from vertical transmission of the Toxoplasma gondii parasite mother to fetus after a primary maternal infection. The risk fetal contamination is higher later term Conversely, severe infection decreases with term; third trimester infections are most often asymptomatic at birth.

Toxoplasma gondii is well- known as a common parasite with high proliferative activity in the nucleated cells. This parasite has infected nearly one third of the people worldwide. Infection can result in chorioretinitis in immunocompetent hosts, encephalitis in HIV/AIDS positive patients and abortion and neonatal loss in congenital toxoplasmosis. Development of vaccines for toxoplasmosis infect...

An immunoglobulin M (IgM)-immunosorbent agglutination assay (IgM-IS-AGA) was negative in all sera from individuals negative in the Sabin-Feldman dye test, in sera from individuals with chronic Toxoplasma infection, and in cord blood samples from uninfected infants. In contrast, all sera that were obtained from individuals with a recent history of acute Toxoplasma infection and from infants with...

Toxoplasma gondii (T. gondii) is a protozoan parasite, infecting most of the warm-blooded animals, including humans who are the intermediate host. Members of cat family Felidae are the definitive hosts. T. gondii infection is acquired by humans by accidental ingestion of oocysts in water, food or soil contaminated with cat feces, or by eating raw or undercooked meat containing cysts. Studies co...

Toxoplasma gondii is an obligate intracellular protozoan parasite causing toxoplasmosis in animals and humans. Primary maternal infection with toxoplasmosis during pregnancy is frequently associated with transplacental transmission to the fetus. However it is not certain whether Toxoplasma infection can cause recurrent abortion. The aim of this study was to determine the relationship between To...

RATIONALE Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis has been recognized as the most frequent autoimmune encephalitis in children. Several infectious agents have been implicated in anti-NMDA encephalitis. PATIENT CONCERNS A previously healthy immunocompetent 9-year-old girl first presented with seizures, headaches and vomiting. Cerebrospinal fluid and brain magnetic resonance ima...

The obligate intracellular parasite Toxoplasma gondii is able to infect nearly all nucleated cell types of warm-blooded animals. This is achieved through the injection of hundreds of parasite effectors into the host cell cytosol, allowing the parasite to establish a vacuolar niche for growth, replication, and persistence. Here we show that Toxoplasma infection actives an inflammasome response i...
