BACKGROUND Toxoplasmosis is a relatively common cause of infectious papillitis and neuroretinitis, which may affect both immunocompetent immunodeficient patients. CASE PRESENTATION A previously healthy woman in her mid-forties presented with subacute onset unilateral blurry vision retrobulbar pain exacerbated by eye movements. Ophthalmological assessment revealed decimal best-corrected visual a...

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...

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...

Symptomatic forms of toxoplasmosis are a serious public health problem and occur in around 10-20% of the infected people. Aiming to improve the molecular diagnosis of symptomatic toxoplasmosis in Brazilian patients, this study evaluated the performance of real time PCR testing two primer sets (B1 and REP-529) in detecting Toxoplasma gondii DNA. The methodology was assayed in 807 clinical sample...

Sir, Toxoplasmosis is a common parasitic infection of humans, to which almost one third of humanity is exposed to [1]. While more than 50% women of child bearing age in Western Europe, Africa, South and Central America are seropositive for toxoplasmosis, some populations of El Salvador, Germany and France show 75% seropositivity, with approximately 90% adults of Paris and 50% adults in Germany ...

Toxoplasmosis is an important parasitic disease in immunosuppressed patients. This prospective study was conducted to determine the seroprevalence, associated risk factors and the incidence of clinically confirmed toxoplasmosis among renal patients at the University of Malaya Medical Center, Kuala Lumpur, Malaysia. We interviewed 247 renal patients, each of whom answered an epidemiological ques...
