BACKGROUND A large number of studies have hypothesized that Toxoplasma gondii is a potentially relevant etiological factor in some cases of schizophrenia. By contrast, some studies have disproved this association. The aim of this study was to investigate whether latent toxoplasmosis has any role in schizophrenia disease. Additionally, the association between T. gondii and subtypes of schizophre...

The distribution of anti-toxoplasma antibodies among the aborigines in Malaysia and its association with other soil transmitted infections and eosinophilia were studied. A total of 415 serum samples were collected and tested by IFA test. Overall prevalence was 10.6%, lower than previously reported. The antibody titers showed a unimodal distribution peaking at 1:8 dilution. There was a higher pr...

The prevalence of Toxoplasma gondii in free-range chickens from Campos dos Goytacazes, Rio de Janeiro State, Brazil, was examined to evaluate environmental contamination by oocysts. Antibodies against T. gondii were assayed by the modified agglutination test

A longitudinal study of different parameters of the immune responses to Toxoplasma gondii was performed with sera of AIDS patients taken during and after clinically important Toxoplasma infections. Follow-up of patients lasted for 9 months on an average. The titres of the specific IgG and IgM antibodies were measured by an indirect fluorescent antibody test (IFAT), and the appearance of circula...

Several researchers have stated that parasites can alter the behavior of their hosts, in order to increase the transmission rate, principally when prey-predator relationships are a reliable way of infection transmission. The aim of this study was to verify the occurrence of changes in anxiety and short-term memory patterns in experimentally infected Mus musculus by Toxocara canis and/or Toxopla...

BACKGROUND Toxoplasmosis is a life-threatening infection in organ transplant recipients, people receiving corticosteroid or radiation therapy, people with malignancies, and AIDS patients. OBJECTIVES The current study aimed to determine the prevalence of toxoplasmosis in patients receiving chemotherapy for malignancies in the Bushehr province of southwest Iran. METHODS Blood samples were tak...

31 Pathological anxiety is thought to reflect a maladaptive state characterized by exaggerated 32 fear. Naturally occurring perturbations that reduce fear can be crucial in the search for new 33 treatments. The protozoan parasite Toxoplasma gondii invades rat brain and removes fear of 34 rats for cat odors, a change believed to be parasitic manipulation of host behavior aimed at 35 increasing p...

background: the effects of extremely low frequency electromagnetic fields (elf-emf) on toxoplasma gondii have not been explained yet. the aim of this study was to assess the possible effects of elf-emf on growth, survival time and viability of toxoplasma gondii . in addition, the life span of toxoplasma infected animals was investigated. methods: sixty adult male balb/c mice were used for in vi...
