Detection of Toxoplasma gondii antigens by a dot-immunobinding technique.
A sensitive assay for the detection of antigens of Toxoplasma gondii by spotting samples directly onto nitrocellulose paper was developed. The sensitivity ranged from 10 to 40 pg of antigen diluted in phosphate-buffered saline and 40 to 130 pg of antigen diluted in normal mouse serum, normal human serum, or human cerebrospinal fluid. T. gondii antigen in serum samples taken from mice infected w...
متن کاملOptogenetic monitoring identifies phosphatidylthreonine-regulated calcium homeostasis in Toxoplasma gondii
Toxoplasma gondii is an obligate intracellular parasite, which inflicts acute as well as chronic infections in a wide range of warm-blooded vertebrates. Our recent work has demonstrated the natural occurrence and autonomous synthesis of an exclusive lipid phosphatidylthreonine in T. gondii. Targeted gene disruption of phosphatidylthreonine synthase impairs the parasite virulence due to unforese...
متن کاملComputer-generated dot maps as an epidemiologic tool: investigating an outbreak of toxoplasmosis.
We used computer-generated dot maps to examine the spatial distribution of 94 Toxoplasma gondii infections associated with an outbreak in British Columbia, Canada. The incidence among patients served by one water distribution system was 3.52 times that of patients served by other sources. Acute T. gondii infection among 3, 812 pregnant women was associated with the incriminated distribution sys...
متن کاملToxoplasma gondii Oocyst–specific Antibodies and Source of Infection
Infection source can determine cost-effective public health interventions. To quantify risk of acquiring Toxoplasma gondii from environmental sources versus from meat, we examined serum from pregnant women in Chile. Because 43% had oocyst-specific antibodies, we conclude that contaminated meat remains the primary source of infection but that environmental sources also pose substantial risk.
متن کاملToxoplasma gondii
A total of 349 human serum samples were examined for anti-Toxoplasma antibodies by the Murex Single Use Diagnostic System (SUDS) qualitative screening test, indirect hemagglutination assay (IHA), and indirect immunofluorescence assay (IFA). Concordant results with SUDS and IHA were obtained for 91.9% of serum samples; 8.9% were SUDS+ and IHA-; none were SUDSand IHA+. Comparison of the SUDS assa...
