The authors evaluated a simple latex agglutination test for the serodiagnosis of acute human leptospirosis. A total of 380 serum samples from 85 confirmed leptospirosis patients and 202 non-leptospirosis patients were selected Using the selected cut-off value of weakly positive, the overall sensitivity and overall specificity of the test were 94.1% and 97.0% respectively. The weighted kappa val...
Linear B-cell epitopes are ideal biomarkers for the serodiagnosis of infectious diseases. However, the long-predicted diagnostic value of epitopes has not been realized. Here, we demonstrated a method, diagnostic epitopes in four steps (DEIFS), that delivers a combination of epitopes for the serodiagnosis of infectious diseases with a high success rate. Using DEIFS for malaria, we identified 6 ...
To evaluate the usefulness of the Korean Isolate-1 (KI-1) antigen for serodiagnosis of toxoplasmosis, antigen profiles of KI-1 tachyzoites were analyzed in comparison with RH tachyzoites by SDS-PAGE and immunoblotting. ELISA was performed on latex agglutination (LA)-positive and negative serum samples using KI-1 and RH antigens. Immunoblotting of the KI-1 antigen showed multiple antigen bands w...
The availability of highly purified lipoarabinomannan from Mycobacterium tuberculosis in its native acylated, highly antigenic state allowed its application to the serodiagnosis of tuberculosis in patients from the Republic of Mexico. Antilipoarabinomannan immunoglobulin G antibodies in sera from 66 patients with pulmonary, miliary, and pleural tuberculosis and tuberculosis lymphadenities were ...
An immunodiffusion technique in agarose is described for assay of complementfixing antibodies against the type-specific soluble antigen of influenza virus. Under the test conditions, positive human serum produced a definite unlysed zone around the well, and the annulus area showed a high correlation with the antibody level in a conventional complement fixation test with log2 serum titer. This p...
We report the evaluation of recombinant severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) nucleocapsid protein enzyme-linked immunosorbent assay (ELISA)-based antibody tests for serodiagnosis of SARS-CoV pneumonia and compare the sensitivities and specificities of this ELISA for detection of immunoglobulin G (IgG), IgM, IgA, and their combinations with serum samples from 149 healt...
The interpretation of dual seroreactivity with human immunodeficiency virus type 1 (HIV-1) and HIV-2 in blood samples is a serious problem facing AIDS researchers worldwide. Some samples of sera from HIV-1-infected patients showed a serological cross-reaction with HIV-2, causing confusion regarding the serodiagnosis. Therefore, we tried to differentiate these serum samples from those containing...
We have developed a new Superagglutination test for serodiagnosis of infectious diseases. It differs from conventional plate/slide agglutination tests (PAT/SAT) by three additional steps: prior staining of serum antibody by adding a dye and addition of diluted biotinylated antiglobulin and avidin in sequence after mixing the antigen with the test serum. The new steps circumvent the problems of ...
Phenolic glycolipid-I (PGL-I), a Mycobacterium leprae-specific antigen, has been widely used for the serodiagnosis of leprosy and has been implicated in the pathogenesis of leprosy. In an effort to produce an alternate antigen of PGL-I, the mimotope peptides of PGL-I, W(T/R)LGPY(V/M), were obtained using a monoclonal antibody, III603.8, specific to PGL-I by a phage library. The biotin-labeled p...
One of the major problems in serodiagnosis in wild animals is unavailability of specific antiglobulin conjugate. Our study focuses on validation of Protein A/G dependent ELISA in game animals like deer and mouflons as well as in hunting dogs. Binding ability of Protein A/G-conjugate to antibodies was the highest in dogs followed by fallow deer and mouflons. Three different whole cell Borrelia a...
