BACKGROUND Toxoplasma gondii, the obligate intracellular parasite is life threatening in AIDS patients. Diagnosis of toxoplasmosis is based on serological methods especially increasing of IgM and IgG titers, but finding of parasite or its components (antigenemia) may be beneficial method in order to detection of acute toxoplasmosis in immunocompromised patients. METHODS Ninety-four serum samp...
After obtaining data indicating the presence of a neutrophil attractant protein-1 (NAP-1)-IgG complex in normal human serum, we developed sandwich ELISAs that could quantify NAP-1 and NAP-1-IgG in mixtures of the two moieties. The ELISA for free NAP-1 used a monoclonal capture antibody that did not bind NAP-1-IgG. The ELISA for NAP-1-IgG was based on omission of the anti-NAP-1 detection antibod...
Accurate serological confirmation of dengue (DEN) infection is difficult, because simple reliable assays for the detection of DEN antibodies are not available. To address this problem, a dipstick enzyme-linked immunosorbent assay (ELISA) was evaluated. The dipstick contained dots of serially diluted DEN 2 antigen. To detect immunoglobulin G (IgG), the dipstick was processed through four reactio...
Nipah virus nucleocapsid (NiV-N) protein was expressed in Escherichia coli and purified by histidine tag-based affinity chromatography. An indirect immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) for human and swine sera and an IgM capture ELISA for human sera were established using the recombinant NiV-N protein as an antigen. One hundred thirty-three suspected patient sera and...
BACKGROUND Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne infectious disease with a high case fatality rate, and is caused by the SFTS virus (SFTSV). SFTS is endemic to China, South Korea, and Japan. The viral RNA level in sera of patients with SFTS is known to be strongly associated with outcomes. Virological SFTS diagnosis with high sensitivity and specificity are required...
In the present study we developed an enzyme-linked immunosorbent assay (ELISA) to measure immunoglobulin M (IgM) specific for glycoinositolphospholipids (GIPL) derived from tachyzoite membrane (IgM-GIPL ELISA). The sensitivity and specificity of the assay were compared with those of commercially available Toxoplasma-specific IgM serological tests, namely, immunofluorescence assay (IFA) with fix...
BACKGROUND & OBJECTIVE Dengue infection is an arthropod borne disease caused by Dengue virus in humans. Dengue virus infection has more potential to produce severe form of the disease with more severe symptoms. Proper diagnosis of dengue fever is very important for its safe management. The objective of this study was to evaluate the non structural protein-1 (NS1) positive parameter for identifi...
Toxoplasma gondii infections in heart transplant recipients were monitored by indirect enzyme-linked immunosorbent assay for immunoglobulin G (ELISA-IgG), indirect ELISA-IgM in serum IgM fractions, antibody capture ELISA-IgM, IgM-immunosorbent agglutination assay (ISAGA), and IgM immunoblotting. Basic immunosuppression consisted of cyclosporine and low-dose steroids. Before transplantation, 26 ...
strongyloidiasis, caused by a nematode parasite so-called strongyloides stercoralis is one of the major human intestinal nematode infections. considering that stool examination for strongyloides larvae is not a sensitive method and immunodiagnostic methods are more applicable for this purpose, so the present study was conducted to compare the somatic (s) and excretory - secretory (es) antigens ...
measles, rubella, mumps, hepatitis b virus (hbv) and varicella zoster virus (vzv) cause infectious diseases that can be effectively prevented by vaccination. vaccination of medical students is important, because they are more likely to become exposed and infected by these viruses. a total of 180 students, consisting of 90 women and 90 men, were serologically screened for measles, rubella and mu...
