The Beverley strain of Toxoplasma gondii produces a chronic infection in mice and other laboratory animals, causing few or no fatalities. There is an immune response to the parasite that can be detected by a variety of serological teclmiques, with however but little understandillg of the significance of the phemmenon.

This is shown by the high prevalence of Toxoplasma antibody, commonly found in 50-60% of human subjects 20-30 years old, in the absence of apparent clinical disease (I). Similarly, serologic surveys have found antibody in normal animals (2). Clinical illness also occurs, however, such as the illness that led to...
متن کاملExperimental toxoplasmosis in hypoiodemic mice
The hypothesis, that hypoiodemia of goats causes such a compromise of the immune system, which during subsequent Toxoplasma gondii infections results in clinically more pronounced signs of toxoplasmosis, was verifying in laboratory mouse. Hypoiodemic mice (fed by wheat and supplied by water), normoiodemic mice (fed by wheat and supplied by water containing 1.25 mg KI/l) and the majority of stan...
متن کاملExperimental Congenital Toxoplasmosis
Pregnant mice infected with Toxoplasma by the vaginal route have been found to transmit toxoplasmosis to the placentas and fetuses in utero. The microorganism entered the blood stream of the mother from primary foci of infection in the vaginal wall and produced disseminated lesions in the labyrinth of the allantoic placenta at the same time as other peripheral maternal tissues were involved. Pl...
متن کاملExperimental toxoplasmosis in budgerigars (Melopsittacus undulatus).
The susceptibility of budgerigars (Melopsittacus undulatus) to graded doses of Toxoplasma gondii oocysts was studied. Sixteen budgerigars were divided into 4 groups (A-D) of 4 each. Birds in groups A-C were fed 100,000, 1,000, or 100 infective oocysts of the VEG strain of T. gondii, respectively. Budgerigars in group D were not fed oocysts and served as controls. All 4 birds in group A died (or...
