Toxoplasmosis may be transferred by organ transplantation. The most common clinical presentation is with multisystem disease, although isolated ocular toxoplasmosis has been described. Many centers have suggested that universal use of co-trimoxazole prophylaxis obviates the need for specific Toxoplasma testing. We report a case of donor-acquired ocular toxoplasmosis after liver transplantation ...

Toxoplasma gondii infection is an important cause of chorioretinitis in the United States and Europe. Most cases of Toxoplasma chorioretinitis result from congenital infection. Patients are often asymptomatic during life, with a peak incidence of symptomatic illness in the second and third decades of life. Diagnosis is mainly supported by ophthalmological examination and a good response to inst...

Background: Toxoplasma gondii is a parasite estimated to affect over 500 million people worldwide. The feline the definitive host for and infection may be acquired or congenital via maternal transmission. Humans acquire by ingestion of raw undercooked meats vegetables, contaminated water, exposure infected cat feces. often benign, self-limiting, asymptomatic humans, but potentially life threate...

AN opportunity presented itself in September and October, 1958, to observe African patients with chorio-retinitis in Kano, Nigeria. Although it was not possible to carry out detailed studies on these patients, blood sera were taken and tested for antibodies to Toxoplasma, a protozoan parasite. The results of these tests are of interest. Wolf, Cowen, and Paige (1938) established toxoplasmosis as...

Four patients with toxoplasmosis are reported with unusual presenting ocular lesions. One patient had an active lesion that appeared to involve the optic nerve as well as focal toxoplasmosis chorioretinitis at the macula. A second patient had a pale optic nerve in association with the classical chorioretinal scars of toxoplasmosis. The third patient had toxoplasmosis chorioretinitis of the macu...

BACKGROUND: Toxoplasmosis is a protozoan parasitic infection. The cerebrospinal, ocular and congenital forms of the disease are complicated and life threatening. Diagnosis of toxoplasmosis is difficult due to invasive sample requirement, complications in pathogenesis, immunology, and interpretation of test results. Using urine as a non invasive sample source for molecular diagnosis of toxoplasm...

background: toxoplasma gondii is an obligate, intracellular protozoon that develops its sexual stage in cat’s intestinal epithelial cells as definitive host and develops its asexual stage in different tissues of a wide range hosts called intermediate host. the protozoon is a food-borne and worldwide parasite that can cause serious complications such as abortion in pregnant women, encephalitis, ...
