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...

The performance of a direct agglutination test for the detection of toxoplasma specific IgG immunoglobulin was compared with that ofthe latex agglutination test. The direct agglutination test was less sensitive but more specific than the latex agglutination test. Quantitative results were not directly comparable, reflecting the different antibody profiles detected in each assay. The direct aggl...

Pregnant women who acquire infection from Toxoplasma gondii usually remain asymptomatic, although they can still transmit the infection to their fetuses with severe consequences. Transmission of T. gondii to the fetus can result in serious health problems, including mental retardation, seizures, blindness, and death. Some health problems may not become apparent until the second or third decade ...

Recent epidemiologic studies indicate that infectious agents may contribute to some cases of schizophrenia. In animals, infections with Toxoplasma gondii can alter behavior and neurotransmitter function. In humans, acute infection with T. gondii can produce psychotic symptoms similar to those displayed by persons with schizophrenia. Since 1953, a total of 19 studies of T. gondii antibodies in p...

One of the first lessons regarding congenital infections taught to third-year medical students on obstetrics and reinforced during their pediatric rotations are the variety and pathogenesis of perinatal viral and parasitic infections that can affect pregnant women and their fetuses. From the time of their residency training, obstetricians have been instructed to counsel their patients about str...

Microbodies are enzyme-containing organelles bounded by a single unit membrane and lacking DNA. The family includes peroxisomes, glyoxysomes and glycosomes. The organelles have a variety of metabolic functions, none of which is present in all members: beta-oxidation of fatty acids, the glyoxylate cycle, alcohol oxidation, and even glycolysis have been found confined within microbodies. Animal c...

(H5N1) virus, suggestive of a cohort effect or otherwise, have yet to be published, although anecdotal reports of completed surveys point to a lack of widespread human infection with the virus (8). Current evidence indicates that pandemic influenza of humans since 1918 has been restricted to 3 influenza A virus subtypes: H1 (1918–57 and 1977–present); H2 (1957–68); and H3 (1968–present) (9,10)....

Parasite differentiation is commonly associated with transitions between complex life cycle stages and with long-term persistence in the host, and it is therefore critical for pathogenesis. In the protozoan parasite Toxoplasma gondii, interconversion between rapidly growing tachyzoites and latent encysted bradyzoites is accompanied by numerous morphological and metabolic adaptations. In order t...

Toxoplasma gondii is an obligate intracellular pathogen within the phylum Apicomplexa. This protozoan parasite is one of the most widespread, with a broad host range including many birds and mammals and a geographic range that is nearly worldwide. While infection of healthy adults is usually relatively mild, serious disease can result in utero or when the host is immunocompromised. This sophist...
