Background: Although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. Objective: The aim of this study was to clone the first 1100 bp of the C. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...
BACKGROUND Clonorchiasis, caused by Clonorchis sinensis, is widely distributed in Southeast Asia including China. Clonorchiasis is included in control programs of neglected tropical diseases by World Health Organization (WHO) because it is one of the major health problems in most endemic areas. Diagnosis of clonorchiasis plays a key role in the control programs. However, so far, there is no sat...
An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of Streptococcus pneumoniae polysaccharide antigen in cerebrospinal fluid and serum. Sensitivity and specificity were determined for purified antigen preparations. Specificity was also evaluated in the rabbit meningitis model, and the sensitivity was compared to counterimmunoelectrophoresis, using the infected rabbits'...
Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...
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...
Antigen tests for infectious diseases are inexpensive and easy-to-use, but the limit of detection (LOD) is generally higher than that PCR tests, which considered gold standard. In present study, we combined a sandwich enzyme-linked immunosorbent assay (ELISA) with thionicotinamide-adenine dinucleotide (thio-NAD) cycling to improve LOD antigen coronavirus disease 2019 (COVID-19). For recombinant...
Varicella-zoster virus (VZV) is a highly contagious agent of varicella and herpes zoster. Varicella can be lethal to immunocompromised patients, babies, HIV patients and other adults with impaired immunity. Serological evaluation of immunity to VZV will help determine which individuals are susceptible and evaluate vaccine effectiveness. A collection of 110 monoclonal antibodies (mAbs) were obta...
Parasitological diagnosis of Trypanosoma evansi infection in camels is hampered by the small number of parasites in blood circulation, coupled with the tendency of this trypanosome to invade tissues. To overcome this, a more sensitive assay, an antigen enzyme-linked immunosorbent assay (ELISA), was developed, capable of detecting trypanosome antigens released into the bloodstream by dying paras...
