The incidences of congenital toxoplasmosis in Fischer rats infected between the 8th and 12th days of pregnancy with three different strains of Toxoplasma gondii (RH, 76K, and Prugniaud) were 58.2, 35.2, and 62.8%, respectively. No infected fetuses were collected from rats previously infected with RH or Prugniaud strain parasites, even if the rats were reinfected during pregnancy. Since pups fro...

Over one billion people worldwide are predicted to harbor Toxoplasma infection frequently with unknown lifelong health consequences. Toxoplasmosis is an important cause of foodborne, inflammatory illnesses, as well as congenital abnormalities. Ubiquitous Toxoplasma has a unique tropism for central nervous system with a mind-bugging effect and is transmitted sexually through semen. Currently ava...

To study the influence of Toxoplasma gondii genotypes on the severity of human congenital toxoplasmosis (asymptomatic, benign, or severe infection or newborn or fetal death), 8 microsatellite markers were used to analyze 86 T. gondii isolates collected from patients with congenital toxoplasmosis. Seventy-four different genotypes were detected, some identical genotypes originating probably from ...

BACKGROUND We present one unusual case of anophthalmia and craniofacial cleft, probably due to congenital toxoplasmosis only. CASE PRESENTATION A two-month-old male had a twin in utero who disappeared between the 7th and the 14th week of gestation. At birth, the baby presented anophthalmia and craniofacial cleft, and no sign compatible with genetic or exposition/deficiency problems, like the ...

Toxoplasma gondii has a clonal population genetic structure with three (I, II, and III) lineages that predominate in North America and Europe. Type II strains cause most cases of symptomatic human infections in France and the United States, although few other regions have been adequately sampled. Here we determined the parasite genotype in amniotic fluid and cerebrospinal fluid samples from con...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. An 8 years old girl suffers from strabismus since her first months of life. Her visual acuity was very low and could only see fingers moving in her left eye. Her left eye fundus showed a chorioretinal scar in the macula due to congenital toxoplasmosis. The biological findi...

Infection with Toxoplasma gondii is acquired through consumption of undercooked infected meat, or by uptake of cat-shed oocysts. Although congenital toxoplasmosis is generally considered to contribute most to the disease burden of T. gondii, ocular disease from acquired infection was recently shown to add substantially to the burden. In addition, toxoplasmosis in immune-compromised individuals ...
