Congenital toxoplasmosis is a worldwide health problem, and different screening strategies exist. Testing of toxoplasma-specific antibodies in infants identifies congenital toxoplasmosis during the first year of life. However, experience with commercial available immunoassays is limited. The aim of this study was to evaluate both the performance and analytical characteristics of the Liaison dia...

The ingestion of uncooked infected meat is considered important in the epidemiology of Toxoplasma gondii infection in humans and little is known of the prevalence of viable T. gondii in meat used for human consumption in the United States. In the present study, viable T. gondii was isolated from 51 out of 55 pigs destined for human consumption. Hearts and tongues (500 g) from fifty-five 6-mo-ol...

In this paper the history of Toxoplasma gondii and toxoplasmosis is reviewed. This protozoan parasite was first discovered in 1908 and named a year later. Its medical importance remained unknown until 1939 when T. gondii was identified in tissues of a congenitally infected infant, and veterinary importance became known when it was found to cause abortion storms in sheep in 1957. The discovery o...

Sera from 180 patients with suspected toxoplasmic lymphadenopathy were examined for antitoxoplasma IgM by an enzyme-linked immunosorbent assay (ELISA), using antibody class capture (ACCA). Of 82 positive ACCA results, 78 were confirmed by testing the IgM fractions of the sera, obtained by sucrose density gradient centrifugation (SDGC). The four positive results which could not be confirmed were...

OBJECTIVE This study was conducted to identify the seroprevalance of diseases which are zoonotic and responsible from abortion such as toxoplasmosis, listeriosis and brucellosis in Holstein crossbred cattle of different age and sex in Adana province, between 2008 April-September. METHODS For this purpose, blood serum samples were collected from 132 cattle and analyzed for Toxoplasma gondii, L...

Protozoal hastalıklar atlarda ölümlere ve ciddi ekonomik kayıplara neden olur. Bazılarının zoonotik potansiyelleri ise halk sağlığı açısından önem arz eder. Bu çalışmanın amacı Nevşehir ilinde turistik amaçlarla yetiştirilen doku (Neospora spp. Toxoplasma gondii) kan (Theileria equi Babesia caballi) protozoonlarının yaygınlığını belirlemektir. amaçla yaşları 3-24 arasındaki 105 dişi attan alına...

There are often discrepancies when using different methods to measure anti-Toxoplasma gondii IgG levels in patient samples. The diagnostic performance of a chemiluminescent immunoassay (CLIA) and an enzyme-linked fluorescent assay (ELFA) used as confirmatory tests for samples identified as positive or equivocal by an electrochemiluminescent immunoassay (ECLIA) were examined. Cut-off values were...
