Toxoplasma gondii is an obligate intracellular protozoan parasite that can infect human and other warm-blooded animals. Although usually asymptomatic in immunocompetent individuals, toxoplasmosis may reactivate in immunocompromised patients (e.g. AIDS patients and organ transplant recipients) and cause severe diseases such as toxoplasmic encephalitis. Moreover, primary maternal infection can pu...
Treatment options for toxoplasmosis in humans are generally limited to the use of sulfonamide and/or pyrimethamine-based compounds. However, there is increasing evidence for clinical therapy failures in patients suggesting the existence of drug resistance in these classes of drug. In vitro resistance to sulfadiazine has been detected in three strains of Toxoplasma gondii isolated from clinical ...
BACKGROUND Recent population structure studies of T. gondii revealed that a few major clonal lineages predominated in different geographical regions. T. gondii in South America is genetically and biologically divergent, whereas this parasite is remarkably clonal in North America and Europe with a few major lineages including Types I, II and III. Information on genotypes and mouse virulence of T...
INTRODUCTION Infection with the ubiquitous parasite Toxoplasma gondii is a threat for immunocompromised patients and pregnant women and effective immune-prophylaxis is still lacking. METHODS Here we tested a mixture of recombinant T. gondii antigens expressed in different developmental stages, i.e., SAG1, MAG1 and GRA7 (SMG), and a lysate derived from T. gondii tachyzoites (TLA) for prophylac...
