The parasite Toxoplasma gondii infects 30–60% of humans worldwide. Latent toxoplasmosis, i.e., the life-long presence cysts in neural and muscular tissues, leads to prolongation reaction times infected subjects. It is not known, however, whether changes observed laboratory influence performance subjects real-life situations. seroprevalence latent toxoplasmosis involved traffic accidents (N = 146) general population living same area 446) was compared by a Mantel-Haenszel test for...
Toxoplasma gondii, a cosmopolitan protozoan parasite, is known to induce behavioural alterations in rodents and may exert an effect on human personality behaviour. The mechanism of parasite-induced host behaviour has not been described, but it was hypothesized that development tissue cysts the brain could affect dopaminergic neuromodulatory system. In this study, we tested latent infection mouse associated with activity system, i.e. locomotion novel environment exploration test....
SUMMARY Several lines of indirect evidence suggest that subjects with latent infection the coccidian parasite Toxoplasma gondii have a higher concentration testosterone than uninfected controls. Here, we searched for direct toxoplasmosis-associated differences in among population 174 female and 91 male students screened infection. We found -infected men to women lower -free The opposite direction shift compared can explain observed gender specificity behavioural shifts subjects.
We present a comprehensive summary of the distribution lizards Iran accompanied by an annotated checklist. The updated maps all 146 species 41 genera 11 families are based on available bibliographic records, catalogues museum collections and our own field observations. final dataset used for contains 8525 georeferenced records cover 41% country when plotted grid 0.25° × resolution. is publicly accessible through GBIF portal (http://www.gbif.org/dataset/7db4f705-61ae-4c6e-9de2-06674e7d46b2)....
SUMMARY Toxoplasma gondii , the coccidian parasite, is known to induce changes in behaviour of its intermediate hosts. The high prevalence this parasite human population (20–80%) offers opportunity studying influence on by screening a normal population. A total 224 men and 170 women were tested for toxoplasmosis their personality profiles measured Cattell's questionnaire. Highly significant differences between -infected uninfected subjects observed ( P < 0·01). For factors G (low superego...
Objective Toxoplasmosis is a lifelong parasitic disease that appears to be associated schizophrenia. However, no distinguishing attributes in T oxoplasma‐ infected schizophrenia patients have been described as yet. Method We searched for differences symptom profile, cognitive performance and treatment response between 194 oxoplasma ‐free 57 (22.7%) ‐infected treated P rague sychiatric C entre 2000 2010. Results Infected non‐infected differed severity of symptoms ( = 0.032) measured with the...
latent toxoplasmosis has been previously found to cause behavioural and personality changes in humans, which are specific for each gender.Here we tested the stress hypothesis of these gender differences based on assumption that causes long-term subliminal stress.In line with this hypothesis, difference will appear specifically situations interpersonal context because contrast typical individualistic coping style men, women have a tendency express elevated prosocial behaviour under...
To determine changes in incidence of reactivation Toxoplasma gondii infection, manifesting as toxoplasmic encephalitis, and to assess the immunological mechanisms controlling HIV-infected patients, a Czech cohort 502 HIV/T. co-infected patients was followed for 2909·3 person-years. The encephalitis between periods before after introduction combination antiretroviral therapy (cART) compared. Toxoplasmic diagnosed 21 patients. In those geometric mean value CD4+ T lymphocytes 12·6 times lower...
Background Toxoplasma gondii, one of the most common parasites, causes toxoplasmosis, frequent zoonotic diseases worldwide. T. gondii infects about one-third world’s population. infection is generally considered a major risk for spontaneous abortion, prematurity and low birth weight in animal sphere. Less commonly, toxoplasma serological profile correlated with particular data delivery. Acute during pregnancy often leads to abortion and/or severe injury eyes, brain, other structures foetus....
Many parasites induce specific changes in host behavior that promote the transmission of their infective stages between hosts. Toxoplasmosis rodents is known to be accompanied by behavioral (shift activity level, learning capacity, and novelty discrimination) can theoretically increase chance infected animals being eaten definitive host, cat. However, toxoplasmosis also many pathological symptoms. It not whether are products manipulation parasite or only nonspecific by-products symptoms...
The heteroxenous protozoan parasite Toxoplasma gondii is transmitted from the intermediate host (any warm-blooded animal) to definitive (members of felidae) by carnivory. infected hosts develop several specific behavioural changes that are usually considered products manipulative activity aimed increase probability its transmission host. Among other changes, rodents were shown have impaired learning capability. All previous studies done 2-6 weeks after infection. Therefore, it was difficult...
SUMMARY The sex ratio may be influenced by many factors, such as stress and immunosuppression, age of parents, parity preceding siblings. In animal systems, parasitism often changes the infected hosts, which can increase probability their transmission. most common human protozoan parasite in developed countries, Toxoplasma gondii (prevalence 20%−80%), is known to change behaviour its intermediate thereby increasing transmission definitive host (the cat) predation. under natural conditions...

One-third of humanity harbors a lifelong infection with Toxoplasma gondii, and probably about 80% are infected human cytomegalovirus (CMV). This study aims to delineate the associations between toxoplasmosis cognitive abilities compare these CMV. We evaluated performance 557 students, who had been examined for CMV infections, using intelligence, memory, psychomotor tests. The results indicated impairments in seropositive individuals both pathogens, variations impact related sex Rh factor....
The latent toxoplasmosis is usually considered to be asymptomatic, however, this paradigm has never been rigorously tested.Here we searched for symptoms of deterioration physical health (decrease weight) in infected people by analysis clinical records 758 women tested the 16th week gravidity.Toxoplasma-positive have a lower body weight gravidity (p = 0.02) than Toxoplasma-negative women.Moreover, negative correlation between and duration was found subset 174 Toxoplasma-positive 0.04),...
The study compares diagnostic parameters of different commercial serological kits based on three antigen types and correlates test results with the status patient's Borrelia infection. In total, 8 IgM IgG were tested, as follows: enzyme-linked immunosorbent assay (ELISA) (Euroimmun) whole-cell antigen, 3 species-specific enzyme immunoassays (EIAs) (TestLine), Liaison chemiluminescence (DiaSorin), ELISA-Viditest (Vidia), EIA, Blot-Line (TestLine) using recombinant antigens. All tests...
A new high-resolution next-generation sequencing (NGS)-based method was established to type closely related European II Toxoplasma gondii strains.
To determine the incidence and laboratory characteristics of primary Toxoplasma gondii infection in HIV-infected individuals.This retrospective study was conducted between 1988 2012 on a cohort 1130 patients at AIDS Center Prague. serology, standard parameters, health status were evaluated 3-6-month intervals for all patients.The total person-time follow-up risk seroconversion 3046.3 years; there 14 T. infections, yielding an rate 0.0046 (95% confidence interval 0.0027-0.0078). Most subjects...
