AIMS To assess the diagnostic usefulness of Toxoplasma gondii tachyzoites produced by serial passage in HeLa cell culture. METHODS Tachyzoites derived from serial passage in cell culture were used in the dye test. Human sera were also examined to determine their suitability for use as accessory factor. Using the optimum conditions, the dye test using cell culture derived tachyzoites was compa...

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...

One of the most refined techniques for investigating morphological processing in word recognition is the variant of the lexical decision task known as repetition priming (Stanners, Neiser, Hernon, & Hall 1979). It provides a primary source of evidence, according to Henderson (1989), of facilitation between words formed from the same morpheme (i.e., morphological relatives). Generally, target (s...

A total of 138 serum samples submitted for toxoplasma serology have been examined by enzyme immunoassay using kits produced by Labsystems Oy for the detection of specific antibodies of the IgG and IgM class. Results were compared with the dye test, an indirect haemagglutination test, and an indirect immunofluorescence test for specific IgM. The enzyme immunoassay was less sensitive than the dye...

Can FD&C Blue no. 1 dye photoinactivate bacteriophages phi X174, T7, PRD1, and phi 6 under laboratory lighting conditions? At high levels of light, the dye (500 microM) photoinactivated only phi 6. Thus, this dye can be used at concentrations up to 500 microM with bacteriophages phi X174, T7, and PRD1 to test barrier material integrity.

The titre of antibodies to Toxoplasma gondii was compared in 1985 sera by use of an indirect haemagglutination test (ToxHA test--Wellcome Reagents Ltd) and the dye test. Sera from 42 patients with clinical or serological indications of recent toxoplasmosis were also examined to determine if the ToxHA test would be of value in detecting early stages of the disease. Nine recent cases of lymphaden...

This test is quick, cheap, simple, and painless. It is adequate in most cases for the diagnosis of achlorhydria. The usefulness of test meals for diagnosing any other gastric abnormality is questionable. The term " achlorhydria " is usually taken to mean that the gastric juice has a pH of more than 3, as shown by Topfer's reagent or thymol blue. It denotes a relative " an "-acidity rather than ...
