based on serological,toxoplasmosis infection is a widespread disease.with regard to this fact and because of the occurence of congenital toxoplasmosis infections due to asymptomatic infections in pregnant women,determination of the rate of toxoplasma antibodise(IgG,IgM) before pregnancy and finding the involved factors in increasing toxoplasmosis prevalence seems to be necessary.in this cross s...
Introduction : Toxoplasmosis, caused by Toxoplasma gondii, is a protozoan parasitic infection distributed worldwide. Early infection by this protozoa can lead to abortion and congenital toxoplasmosis in pregnant women. This study was conducted to determine the seroprevalence of T. gondii infection among pregnant women referring to Shahid Akbar Abadi Hospital, Tehran, Iran during 2010-2013. Meth...
Background and objective: Helicobacter pylori infection is one of the most common chronic bacterial infections in the world, especially in the developing countries. This bacterium is the cause of many diseases such as lymphoma, gastritis, peptic ulcers, and stomach cancer. According to recent reports, H. pylori infection can potentially increase the risk of colon cancer. The cu...
An enzyme-linked immunosorbent assay (ELISA) for the detection of IgG antibodies against the pandemic H1N1 2009 influenza A virus, employing a recombinant hemagglutinin protein of the virus, was compared to the hemagglutination inhibition (HI) test using 783 serum samples. The results showed a concordance of 98.4%, suggesting the utility of the ELISA in serosurveillance. Two hundred sixty-nine ...
abstract aim: to assess anti-neuronal antibodies (na) prevalence and their correlation with neurological disorders and bowel habits in celiac disease (cd) patients. background: neurological manifestations are estimated to occur in about 10% of celiac disease patients and na to central nervous system (cns) and enteric nervous system (ens) are found in a significant proportion of them. little is ...
Background and Objective: The most important concern associated with diagnosing congenital toxoplasmosis is to determine when the mother has been infected. The importance of using serological diagnostic tests such as IgG-avidity assay which can distinguish between recent and past infections has been proven. The present study aimed to diagnose acute toxoplasmosis in the first trimester of pregna...
Understanding host antibody response is crucial for predicting disease severity and for vaccine development. We investigated antibody responses against influenza A(H7N9) virus in 48 serum samples from 21 patients, including paired samples from 15 patients. IgG against subtype H7 and neutralizing antibodies (NAbs) were not detected in acute-phase samples, but ELISA geometric mean titers increase...
Family history of type 1 diabetes and autoantibodies to the islet antigens insulin (IAA), glutamate decarboxylase (GADA), and the protein tyrosine phosphatase-like protein IA-2 (IA-2A) are strong predictors of type 1 diabetes, but the rate of progression to diabetes in multiple islet autoantibody-positive relatives varies widely. We asked whether detailed characterization of islet autoantibodie...
The pneumococcal polysaccharide vaccine is recommended as a means of preventing invasive disease in the elderly. We compared responses to the 23-valent polysaccharide vaccine in 46 previously unvaccinated, healthy, institutionalized elderly persons (mean age, 85.5 years) with those in 12 healthy younger adults (mean age, 37 years) by measuring prevaccination and postvaccination serum IgG antibo...
