BACKGROUND Latent toxoplasmosis, the life-long presence of dormant stages of Toxoplasma in immunoprivileged organs and of anamnestic IgG antibodies in blood, affects about 30% of humans. Infected subjects have an increased incidence of various disorders, including schizophrenia. Several studies, as well as the character of toxoplasmosis-associated disturbance of neurotransmitters, suggest that ...

BACKGROUND Well-documented outbreaks of human toxoplasmosis infection are infrequently reported. Here, we describe a community outbreak of multivisceral toxoplasmosis that occurred in Patam, a Surinamese village near the French Guianan border. METHODS From the end of December 2003 through the middle of January 2004, 5 adult patients in Patam, including 2 pregnant women, were initially hospita...

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...

The behavior of CSF inflammatory pattern in patients with AIDS and/or toxoplasmosis of the CNS is studied in 176 patients, divided in three groups. In the first group, 96 patients with toxoplasmosis and AIDS are considered; in the second group, 50 patients with toxoplasmosis without AIDS; in the third group, 30 AIDS patients without toxoplasmosis nor any other opportunistic infection. It is pos...

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 Toxoplasmosis is an uncommon disease in immunocompetent people. CASE CHARACTERISTICS We report an adolescent boy with central nervous system toxoplasmosis who presented with progressive lower cranial nerve palsies and a ring-enhancing lesion on neuroimaging. INTERVENTION Diagnosis of toxoplasmosis was confirmed on histopathology of the excised lesion. MESSAGE Toxoplasmosis shou...

Toxoplasma gondii causes fatal and debilitating brain and eye diseases. Medicines that are currently used to treat toxoplasmosis commonly have toxic side effects and require prolonged courses that range from weeks to more than a year. The need for long treatment durations and the risk of relapsing disease are in part due to the lack of efficacy against T. gondii tissue cysts. The challenges for...

HLA-A, HLA-B, HLA-C, and HLA-D typing was performed in 47 mothers of patients suffering from ocular toxoplasmosis to investigate whether an immunogenetic predisposition exists for developing congenital toxoplasmosis in their offspring. No significant association between any HLA antigen was observed in the mothers of patients with ocular toxoplasmosis, although a total absence of the HLA-B51 ant...

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 ...

Intra-cranial toxoplasmosis is a rare entity occurring mostly in immunosuppressed individuals. It is extremely rare in an immune competent patient. Toxoplasmosis is the third leading cause of food borne illness. Depending upon the site, degree of inflammation and local damage, toxoplasmosis encephalitis and cranial abscess can cause long lasting neurologic sequel. With modern imaging techniques...
