trichomoniasis is a worldwide infection and due to its complications rapid and accurate diagnosis of infection especially in pregnant women is very important. in this study, development of a latex agglutination test using native antigens for rapid diagnosis of trichomoniasis is investigated. trichomonas vaginalis was harvested from tyis33 culture medium and anti trichomonas vaginalis antiserum ...

The ability of a rapid, latex agglutination test to diagnose rubella infection and to measure immune status was evaluated by comparison with the hemagglutination-inhibition (HAI) test, enzyme-linked immunosorbent assay (ELISA), and the neutralization (NT) test. The latex agglutination test accurately detected serological conversions in 74 pairs of sera representing 21 natural infections and 53 ...

A total of 163 stool specimens were tested for detection of Clostridium difficile and its toxin by cytotoxicity assay with tissue culture, latex agglutination test, and isolation of the organism. From 33 specimens which were positive for toxin by cytotoxicity, 30 were positive by the latex agglutination test; the organism was isolated from 21. The total number of samples which were positive wit...

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...

OBJECTIVES To compare the performance of three diagnostic methods for Trichomonas vaginalis infection-latex agglutination, saline wet mount, and culture. METHODS Vaginal swabs from 3807 women attending antenatal clinics were tested for the presence of T vaginalis by latex agglutination. All positives and the following two negatives were tested by wet preparation and culture. RESULTS The pre...

different examination have shown that rheumatoid factor is not responsible for false positive reaction (f.p.r.) in cr. neoformanse’s free capsular antigen latex agglutination test, whereas high levels of iron in sera of patients with rheumatoid arthritis as well as other sera was responsible not only for this f.p.r. , but also had an important role in the production of f.p.r. in many slide late...

Following the outbreak of Legionnaires' disease in Stafford in 1985, 500 serum samples were submitted to the indirect immunofluorescence antibody test and a latex agglutination. Latex agglutination using ultrasonically disrupted Legionella pneumophila antigens coupled to latex particles, proved a rapid, simple method for detecting circulating antibodies to L pneumophila in a one minute slide la...

One hundred sera from 49 patients with glandular toxoplasmosis were examined by a latex agglutination test, the dye test, an indirect haemagglutination test, and a double antibody sandwich enzyme linked immunosorbent assay (ELISA) for antitoxoplasma IgM. The results support previous findings that the dye test, indirect haemagglutination test, and latex agglutination test measure different antib...

rheumatoid factors (rf) are autoantibodies with specificity for the fc portion of human igg. production of rf is a characteristic feature of rheumatoid arthritis (ra) and is detectable in high titer in about 90% of these patients. in this study, we measured total igm, iga, igmrf and igarf in serum and synovial fluid of 45 ra patients by elisa and the results were compared with those obtained by...
