background: this study was conducted to investigate the influence of toxoplasma gondii infection on spermatic and hormonal parameters in a pilot sample of immunocompe­tent human male subjects. methods: this cross sectional, observational pilot study on 60 immunocompetent hu­man male subjects aged between 18 and 60 yr old was conducted between 2012 -2013. blind evaluation of serological markers ...

Helicobacter pylori and latent toxoplasmosis are widespread diseases that have been associated with cognitive deficits and Alzheimer's disease. We sought to determine whether interactions between Helicobacter pylori and latent toxoplasmosis, age, race-ethnicity, educational attainment, economic status, and general health predict cognitive function in young and middle-aged adults. To do so, we u...

Toxoplasma infection in pregnant women may cause congenital toxoplasmosis. Diagnosis of infection is based on serological tests aimed at detecting IgM and IgG antibodies against Toxoplasma gondii. However, IgM antibodies are not an accurate marker for discriminating between acute and latent infection. Detection of residual or persistent IgM may occur months or even years after primary infection...

The influence of latent toxoplasmosis on the phenotype , especially on the behaviour, of intermediate hosts has been intensively studied since the mid-1990s. The number of papers dealing with this topic that can be found in the Web of Knowledge SM by using the combination of terms toxoplasm* AND (behavi* OR psychol* OR per-sonalit* OR psychiatri* OR schizophr*) is rapidly in-Most of these paper...

toxoplasmosis is one of the most common parasitic diseases worldwide. although estimated that one third of the world's population are infected with toxoplasma gondii , but the most common form of the disease is latent (asymptomatic). on the other hand, recent findings indicated that la­tent toxoplasmosis is not only unsafe for human, but also may play various roles in the etiol­ogy of different...

BACKGROUND Toxoplasmosis, one of the most common zoonotic diseases worldwide, can induce various hormonal and behavioural alterations in infected hosts, and its most common form, latent toxoplasmosis, influences the course of pregnancy. Autoimmune thyroid diseases (AITD) belong to the well-defined risk factors for adverse pregnancy outcomes. The aim of this study was to investigate whether ther...

According to studies, latent Toxoplasma gondii infection may affect several functions of the human brain. Here we search for the association between latent toxoplasmosis and cognitive performance. We tested 70 individuals for latent T. gondii infection. There were 26 Toxoplasma-infected subjects and 44 Toxoplasma-free subjects. Within these two groups we assessed cognitive performance using a s...

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, ...

The latent toxoplasmosis is usually considered to be asymptomatic, however, this paradigm has never been rigorously tested. Here we searched for symptoms of deterioration of physical health (decrease of weight) in infected people by analysis of clinical records of 758 women tested for toxoplasmosis in the 16th week of gravidity. Toxoplasma-positive women have a lower body weight in the 16th wee...

BACKGROUND Latent toxoplasmosis, the life-long presence of dormant stages of Toxoplasma in immunoprivileged organs and of anamnestic IgG antibodies in blood, affects about 30% of humans. Infected subjects have an increased incidence of various disorders, including schizophrenia. Several studies, as well as the character of toxoplasmosis-associated disturbance of neurotransmitters, suggest that ...
