background: toxoplasmosis is a world wide parasitic disease infecting human by oocyst, tissue cyst or tachyzoites in raw meat, water or congenitally during pregnancy. toxoplasmosis can cause abortion in pregnant women. the current seroepidemiological study was designed to assess toxoplasmosis in pregnant women with or without the history of abortion. methods: in a case–control study the antibod...
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...
Background Toxoplasmosis is an infection that affects almost a third of the world population. In adults, it is often asymptomatic, although having important manifestation in children- infected by placental transmission. The prenatal is an important moment, requiring actions in women's care during pregnancy, in order to prevent diseases that could compromise the mother and the child's life. Me...
Untreated acute toxoplasmosis among pregnant women can lead to serious sequelae among newborns, including neurological impairment and blindness. In Brazil, the risk of congenital toxoplasmosis (CTox) has not been fully evaluated. Our aim was to evaluate trends in acute toxoplasmosis prevalence from 1998-2005, the incidence of CTox and the rate of mother-to-child transmission (MTCT). A cross-sec...
BACKGROUND Toxoplasmosis is an important, widespread, parasitic infection caused by Toxoplasma gondii. The chronic infection in immunocompetent patients, usually considered as asymptomatic, is now suspected to be a risk factor for various neurological disorders, including epilepsy. We aimed to conduct a systematic review and meta-analysis of the available literature to estimate the risk of epil...
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: Toxoplasmosis has a more severe manifestation in pregnant women and immunocompromised individuals. Up to 15% of immunocompetent individuals who have acquired the infection may be asymptomatic, however others symptoms confused with another cause manifestations such as ocular toxoplasmosis which is most common chorioretinitis can lead retinal necrosis. Considering that clinical charac...
BACKGROUND ROP16 is a protein kinase of Toxoplasma gondii identified in the mouse model as a virulent marker, but it is unknown whether this finding is relevant in human toxoplasmosis. METHODS We obtained the Toxoplasma ROP16 locus DNA sequence in samples from 12 patients with ocular toxoplasmosis, 1 sample from a patient with congenital toxoplasmosis, 22 samples from soldiers operating in th...
A large amount of research has been done on toxoplasmosis in the last 30 years, and the world-wide incidence of the infection, and its clinical manifestations, are recognized and documented in an extensive literature. New discoveries concerning the life-cycle of the organism (Frenkel, I970; Hutchison, Dunachie, Siim, and Work, I970) promise to solve many of the problems of the transmission of i...
BACKGROUND In immunocompetent patients, acute toxoplasmosis is usually asymptomatic. We identified M1 macrophages in a case of symptomatic acute Toxoplasma gondii infection that resolved without treatment. M1 macrophages have been demonstrated in animal models of toxoplasmosis, but not in humans. CASE PRESENTATION A 63-year-old woman presented with laterocervical and axillary bilateral lympha...
