Toxoplasmosis caused by an obligate intracellular protozoan parasite Toxoplasma gondii is a very common infection among young adults in diVerent parts of the world. Most of the toxoplasma infections are asymptomatic, the diagnosis relies mainly on the results of serological tests. The clinical implications of toxoplasma infection in pregnant patients are manifold. Such patients may have spontan...

A positive Toxoplasma immunoglobulin M (IgM) result is often interpreted as a marker of an acute infection. However, IgM can persist for several years, and Toxoplasma commercial IgM diagnostic test kits can yield a number of false-positive results. For these reasons, a chronic Toxoplasma infection can be erroneously classified as an acute infection, resulting in serious adverse consequences, es...

Several lines of indirect evidence suggest that subjects with latent infection of the coccidian parasite Toxoplasma gondii have a higher concentration of testosterone than uninfected controls. Here, we searched for direct evidence of latent toxoplasmosis-associated differences in testosterone concentration among a population of 174 female and 91 male students screened for Toxoplasma infection. ...

In mice infected with an avirulent strain of Toxoplasma gondii, circulating Toxoplasma antigens were detectable in the sera during weeks 1 to 3 of infection by a simple agglutination test that uses latex particles coated with anti-Toxoplasma antibodies. An infection in athymic nude mice resulted in high agglutination titers in the anti-Toxoplasma antibody-coated latex particle test and the abse...

2 SUMMARY Between 20 % and 60 % of the population of most countries are infected with the protozoan Toxoplasma gondii. Subjects with clinically asymptomatic lifelong latent toxoplasmosis differ from those who are Toxoplasma free in several behavioral parameters. Case-control studies cannot decide whether these differences already existed before infection or whether they were induced by the pres...

Toxoplasmosis is a major and preventable cause of severe visual handicap blindness among young people. More specifically, retinochoroiditis (TRC) caused by Toxoplasma gondii rare but serious manifestation toxoplasma infection. There are only two probable means acquiring the disease, through congenital route acquired. In Philippines, there few reported cases studies about TRC in human population...

Toxoplasmosis is one of the most common opportunistic parasitic diseases in patients living with HIV/AIDS. This study aimed to determine the seroprevalence of Toxoplasma infection in HIV-infected patients and to identify associated risk factors in Toxoplasma seropositive patients. This study was conducted at a regional public hospital in Hat Yai, southern Thailand during October 2009 to June 20...

Toxoplasma gondii, a cosmopolitan protozoan parasite, is known to induce behavioural alterations in rodents and may exert an effect on human personality and behaviour. The mechanism of parasite-induced alterations in host behaviour has not been described, but it was hypothesized that development of Toxoplasma tissue cysts in the brain could affect the dopaminergic neuromodulatory system. In thi...
