The current COVID-19 pandemic is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). A better understanding of its immunogenicity can be important for development improved diagnostics, therapeutics, and vaccines. Here, we report longitudinal analysis three patients with moderate (#1) mild disease (#2 #3). Antibody serum responses were analyzed using spike glycoprotein en...
Detection of helicobacter pylori (H. pylori) by invasive methods is costy and unpleasant for patients and is not free form complication ,thus in our study we evaluated an enzyme linked immunosorbent assay (ELISA) for measurement of H. pylori specific IgG in saliva in comparison with biopsy urease test and serum IgG.from 100 patients consult gastrointestinal in Najaf Hospitals during the period ...
During Bordetella pertussis infection, it has been established that an increase of anti-pertussis toxin (PT) and anti-filamentous hemagglutinin (FHA) antibodies occurs. Immunoblots from two manufacturers using FHA and PT antigens were compared with an enzyme-linked immunosorbent assay (ELISA) that used both FHA and PT. One manufacturer used two concentrations of PT bands for the IgG immunoblot,...
OBJECTIVES The aim was to investigate a possible relationship between Chlamydia pneumoniae and Parkinson's disease (PD). STUDY DESIGN Serum samples obtained from a cohort of 51 patients with PD and from 37 age- and sex-matched controls were assessed for the presence of antibodies. The control group was selected from healthy people. In both groups, 5 mL of blood was taken and after centrifugat...
Objective A task force of scientists at the International Congress on Antiphospholipid Antibodies recognized that phosphatidylserine-dependent antiprothrombin antibodies (aPS/PT) might contribute to a better identification of antiphospholipid syndrome (APS). Accordingly, initial and replication retrospective, cross-sectional multicentre studies were conducted to ascertain the value of aPS/PT fo...
BACKGROUND Serosurveys that measure tetanus antitoxin can complement immunization coverage surveys to allow evaluation of immunization services in developing countries. Measurement of IgG tetanus antitoxin in oral fluid was investigated as a practical and noninvasive alternative to and correlate of serum antibodies. METHODS Serum and oral fluid were collected from Malian infants, toddlers and...
Bacteriological isolation of Yersinia pestis is the reference test for confirming plague infection, but recovery of the pathogen from human samples is usually very poor. When the etiology of the disease cannot be bacteriologically confirmed, it may be useful to possess alternative tests such as detection of specific circulating antibodies to help guide the diagnosis. In the present study, the i...
The specific IgG antibodies to thermophilic actinomycetes in the sera from patients with farmer's lung disease were quantitated by an ELISA and the results thereof were compared with those obtained by the standard double immunodiffusion assay (Ouchterlony's method). All sera from patients with farmer's lung disease were precipitin positive to Thermoactinomyces vulgaris and/or Micropolyspora fae...
AIM to evaluate the specificity of the SARS-CoV N protein-based IgG ELISA assay for detection of immunoglobulin G (IgG) in plasma samples obtained from HIV-1 positive and HIV-1 negative intravenous drug users (IDUs). METHODS the SARS-CoV N gene was cloned into pQE-80L vector, and the constructs were transformed into Escherichia coli BL21. The 6x His-tagged N protein was expressed by inducing ...
Labeled avidin-biotin (LAB) enzyme-linked immunosorbent assay (ELISA) was applied to detect Japanese encephalitis OE) antibody in swine sera. Purified laGAr-01 vaccine of lE, biotin labeled anti-swine Ig or IgM rabbit IgG conjugate and horseradish peroxidase (HRP) were employed in the assay. The f1 chain specific anti-IgM conjugate could detect only IgM antibody, but the anti-Ig conjugate could...
