the aim of this study was to determine the seroprevalence of toxoplasma gondii in mares and stallionsin the province of ankara. sera from 168 clinically healthy horses were tested for the presence oftoxoplasma gondii antibodies using the sabin feldman dye test. toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

A simple and efficient method using transgenic Toxoplasma gondii tachyzoites expressing beta-galactosidase was developed for detection of specific antibodies against the parasite in sera of patients. The titers obtained with the new test were similar to those obtained with the Sabin-Feldman dye test run in parallel. Although significant changes in endpoint titers were not observed when sera dra...

The prevalence of chronic Toxoplasma infections reported in the literature varies enormously. We hypothesize that one factor could be due to the different methods used in the evaluation of infections. Serological evidence of Toxoplasma infections in 450 pregnant women (PW) and 300 HIV-infected patients (HIV) were investigated by the Sabin-Feldman dye test and two other commercial ELISA kits (ki...

Toxoplasma gondii can infect all species of warm-blooded animals, including humans, and causes serious diseases in immunocompromized hosts. Live tachyzoites derived from serial passage in HeLa culture were used in the Sabin-Feldman dye test for detection of Toxoplasma gondii antibody in serum samples of 21 captive wild felids including one fishing cat (Prion nailurus viverrina), one leopard (Pa...

The predictive value of commercial latex agglutination kit (Toxo-Screen DA, bioMerieux) was assessed for use as screening test for Toxoplasma IgG antibody. The sensivity and specificity were also compared with those of the reference standard Sabin-Feldman dye test. Five hundred serum samples were collected from 200 blood donors and 100 each from pregnant women, kidney recipients and HIV infecte...

Although the Sabin-Feldman dye test is the gold standard for detecting Toxoplasma antibodies in human, it is performed only in reference laboratories because live virulent T. gondii are used for the test. We collected 210 human serum samples and tested them by the dye test using in vivo tachyzoites (conventional method) then compared these results with three other methods: a dye test using cell...

Serum samples from 101 stranded or bycatch cetaceans from British waters were screened for Toxoplasma gondii-specific antibodies using the Sabin Feldman Dye Test. Relatively high seropositivity was recorded in short-beaked Delphinus delphis and this study presents the first documented case of Toxoplasma in a humpback whale Megaptera novaeangliae.

When a physician is confronted with a patient suffering from heart failure of obscure oetiology, toxoplasmosis is one of the possible causes to be considered. The difficulties of diagnosis are considerable, and usually the elucidation of the case must rest on the indirect evidence of the complement fixation test (c.f.t.) and the Sabin-Feldman dye test. Therefore, unless the diagnosis is conside...
