USE 0F ENZYME LINKED IMMUNOSORBENT ASSAY (ELISA) FOR THE DIAGNOSIS OF BRUCELLOSIS IN CATTLE IN YUCATAN, MEXICO. Sera (247) from non-vaccinated brucellosis negative herds, 328 negative sera from Brucella abortus strain 19 vaccinated herds (brucellosis free), and 95 sera positive to the Rose Bengal test (RBT) and Complement Fixation test (CFT) from Brucella abortus-infected herds, were used to de...
The performance of a direct sandwich enzyme-linked immunosorbent assay (ELISA) for detecting Aspergillus galactomannan was compared with that of the Pastorex Aspergillus antigen latex agglutination (LA) test by using 532 serum samples from 61 patients at risk for invasive aspergillosis. The ELISA gave positive results earlier in the course of infection than did the LA test. A sensitivity of 70%...
Paratuberculosis (PTB) is a major disease problem worldwide, and causes major economic losses in the dairy industry. Although PTB has been reported in Korea, no studies have been conducted to determine its prevalence and no program has been developed to control the disease. In this study, the sera of beef (n = 1,056) and dairy cattle (n = 1,105) from all provinces in Korea were tested to determ...
the main objective of this study was to estimate the seroprevalence of bovine herpes virus type 1 and parainfluenza type 3 in a non-vaccinated population cattle in the livestock region of qazvin province. totally 504 sera were randomly collected and tested from 8 industrial dairy farms in qazvin province during march 2010-march 2011. the result of one way analysis of variance was used for th...
BACKGROUND We compared the performance of two new commercial tests for the detection of dengue NS1 protein during the clinical phase of dengue virus (DENV) infection-an immunochromatographic test allowing rapid detection of the NS1 antigen, Dengue NS1 Ag STRIP (Bio-Rad Laboratories - Marnes La Coquette, France), and a two-step sandwich-format microplate enzyme-linked immunosorbent assay (ELISA)...
A Comparison of Immuncapture Agglutination and ELISA Methods in Serological Diagnosis of Brucellosis
BACKGROUND Different serological tests are used in serologic diagnosis of brucellosis. The most widely used of these are Standard Tube Agglutination and Coombs anti-brucella tests. Whereas ELISA Ig M and Ig G tests have been in use for a long time, immuncapture agglutination test has been recently introduced and used in serological diagnosis. The aim of this study was to compare diagnostic valu...
The disappearance of the e antigen and the appearance of anti-e antigen antibodies are two biomarkers that indicate favorable prognosis in Hepatitis B. In this study the Advanced Quality immunochromatographic test for detecting those biomarkers was compared to the Vidas semi-quantitative ELISA test. Our hypothesis was that it is possible to use these biomarkers measured in a rapid and simple Ad...
BACKGROUND The objectives of this study were to determine the proportion of malaria, bacteraemia, scrub typhus, leptospirosis, chikungunya and dengue among hospitalized patients with acute undifferentiated fever in India, and to describe the performance of standard diagnostic methods. METHODS During April 2011-November 2012, 1564 patients aged ≥5 years with febrile illness for 2-14 days were ...
