Among the diagnostic problems requiring a retrospective assessment of the time an event occurred is that of screening for primary infection with Toxoplasma gondii acquired during pregnancy. We suggest a method to derive the possible times of onset of infection from a small sequence of serological samples by matching them against the knowledge about possible courses of infection. Special care is...

Background: Toxoplasmosis is a parasitic disease caused by protozoan, Toxoplasma gondii. Infections of human are common and are usually asymptomatic. The infection may be serious if is transmitted to the fetus during pregnancy. Prophylactic measures, early detection of the infection and treatment can avoid congenital toxoplasmosis and many long term effects. Objective: Seroepidemiological study...

To estimate the burden of disease due to congenital toxoplasmosis in Sweden the incidence of primary infections during pregnancy and birth prevalence of congenital toxoplasmosis in 40,978 children born in two regions in Sweden was determined. Women possibly infected during pregnancy were identified based on: 1, detection of specific IgG based on neonatal screening of the phenylketonuria (PKU) c...

INTRODUCTION Many cases of congenital toxoplasmosis can be prevented provided that pregnant women following hygienic measures to avert risk of infection and to reduce severity of the condition if primary prevention failed. OBJECTIVES This descriptive exploratory study aimed to assess the risk behavior and knowledge related to toxoplasmoisis among Saudi pregnant women attending primary health ...

In 1991-1997 educational activities were undertaken in the Poznań region of Poland to promote health education for the prevention of toxoplasmosis. The effect of education was measured in 2710 pregnant women by a questionnaire survey. Knowledge of toxoplasmosis and its prevention was almost doubled within 4 years. Similarly, the proportion of women having antenatal serological tests for toxopla...

Introduction Mrs M., a 30 year-old lecturer in psychology is expecting her second baby. Her first baby was born while she was on sabbatical in France. During that pregnancy she was screened for Toxoplasmosis, found to be non-immune and had repeated monthly screening throughout her pregnancy. The consensus in France is to screen all pregnant women for toxoplasmosis at the first visit, and to off...

Acute infections by the protozoan Toxoplasma gondii during pregnancy (gestational toxoplasmosis) are known to cause serious health problems to the fetus (congenital toxoplasmosis). In Brasília, there have been few studies on the incidence of toxoplasmosis. This report summarizes a retrospective study performed on 2,636 selected pregnant women attended by the public health system of Guará, a sat...

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...

The immunopathogenesis of toxoplasmosis during pregnancy is not completely understood. This paper will try to discuss the most frequently asked questions about the immunopathogeny of congenital toxoplasmosis: differential virulence of Toxoplasma isolates, genetic susceptibility to infection, facilitation of placental transfer, models of congenital toxoplasmosis, and transmission in seropositive...
