background: toxoplasma gondii , an apicomplexan parasite, is capable of infecting a broad range of intermediate warm-blooded hosts including humans. the parasite seems to be capable of altering the natural behavior of the host to favor its trans-mission in the environment. the aim of this study was to evaluate the course, alter-ations in behavior along with normal kinetics of the abnormally ind...

Description of a case of acute acquired ocular toxoplasmosis following hantavirus pulmonary syndrome. A 41-year-old man presenting hantavirus pulmonary syndrome, confirmed in the laboratory by detection of IgM antibodies to the virus, was submitted to high doses of intravenous corticosteroids for two months. After clinical improvement of hantavirus pulmonary syndrome the patient presented visua...

The aim of this study was to test the potential diagnostic usefulness of recombinant Toxoplasma gondii rhoptry antigens, ROP2 and ROP4, with respect to toxoplasmosis detection and infection phase distinction in laboratory mouce by determining specific serum IgM and IgG antibodies with the use of indirect ELISA technique. The mice antibody response to ROP antigens was significantly higher in the...

The development of IgG avidity assays has revolutionised serological diagnosis of Toxoplasma infections. The measurement of IgG avidity has shown its power in various clinical settings, especially in situations where timing and differentiation of primary and secondary infections is crucial. However, no laboratory test performed alone is self-sustained, whereby the diagnostic strategy of choice ...

Background: To evaluate whether the treatment of the pregnant women associated with a lack of monitoring for toxoplasmosis seroconversion affected the prognosis of the patients Methods: Cohort study with 292 newborns at risk for congenital toxoplasmosis, in Goiânia-GO (Brazil), between October 2003 until October 2011. We carried out statistical analysis in order to test the efficacy of maternal...

BACKGROUND Acquired toxoplasmosis more frequently goes unrecognized. Immunocompetent adults and adolescents with primary infection are generally asymptomatic, but symptoms may include malaise, fever, and lymphadenopathy. By contrast, immunocompromised patients may experience severe manifestations including encephalitis and multisystem organ failure. CASE PRESENTATION We report a case of polym...

BACKGROUND Toxoplasmosis is a life-threatening infection in organ transplant recipients, people receiving corticosteroid or radiation therapy, people with malignancies, and AIDS patients. OBJECTIVES The current study aimed to determine the prevalence of toxoplasmosis in patients receiving chemotherapy for malignancies in the Bushehr province of southwest Iran. METHODS Blood samples were tak...

Hospital Physician July 2008 17 T oxoplasma gondii is an obligatory intracellular pathogen that infects a large proportion of the world population and is a well-recognized cause of illness among persons with AIDS.1 T. gondii infection typically is latent and remains asymptomatic in both immunocompetent individuals and HIV-infected patients. However, patients with HIV are at risk for developing ...

Toxoplasma gondii causes congenital toxoplasmosis in newborns resulting with fetal anomalies. Determining the initiation time of infection is very important for pregnant women and current serological assays have drawbacks in distinguishing the recently acute toxoplasmosis. Diagnosis of recently acute infection may be improved by using stage specific antigens in serological assays. In the presen...

INTRODUCTION Toxoplasma gondii is an obligate intracellular protozoan that infects up to one-third of the world's population. Although this case is not the first of its kind, it is clinically important since it will help doctors keep a broad differential diagnosis in mind when attending to similar patients. CASE PRESENTATION We present the case of a 20-year-old man of Middle Eastern heritage ...
