The serological detection of specific antibodies to Treponema pallidum is of particular importance in the diagnosis of syphilis. The purpose of this study was to evaluate diagnostic performances of automated immunoassays in comparison with T. pallidum hemagglutination test (TPHA) and Western Blot (WB). The retrospective study was performed with different panels of sera: 244 clinical and serolog...
Rapid antibody detection has been used widely as a diagnostic aid in the diagnosis of tuberculosis (TB), especially for bacterium-negative TB. We evaluated the diagnostic value of four commercial antibody detection kits with 501 sera from TB patients and controls. The sensitivities and specificities of the four kits were as follows: (1) Rapid test A 71.8% and 91.4% (85.5% for non-TB diseases an...
The periodic emergence of new infectious agents and the genetic and antigenic evolution of existing agents necessitate the improvement of technology for the rapid development of diagnostic assays. The porcine epidemic diarrhea virus (PEDV) emerged in the United States in 2013, causing severe economic damage to the pork industry. The primary goal of this study was to develop methods to reduce th...
Porcine circovirus type 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) are major contributors to the porcine respiratory disease complex (PRDC). Routine serological diagnosis and surveillance play an important role in the prevention of PRDC, as it is a leading cause of economic losses to the swine industry. We herein describe an advanced microsphere-based immunoassay t...
the internal infections of erwinia amylovora have important roles for disease beginning in the spring and dissemination of inoculum through infected vegetative planting material and nursery trees. in this study, we survey internal infection of erwinia amylovora in symptomless commercial apple cultivars in karaj and damavand cities, using optimized diagnostic methods such as plating on semi sele...
INTRODUCTION Chlamydia antibody testing (CAT) in serum has been introduced as a screening method in the infertility workup. We evaluated the test characteristics of two ELISA tests compared to micro-immunofluorescence tests (MIFs). MIFs are considered the gold standard in the C. trachomatis IgG antibodies detection. We also compared the accuracy of all CAT tests in predicting tubal subfertility...
BACKGROUND Interpretation of serological assays in Lyme borreliosis requires an understanding of the clinical indications and the limitations of the currently available tests. We therefore systematically reviewed the accuracy of serological tests for the diagnosis of Lyme borreliosis in Europe. METHODS We searched EMBASE en MEDLINE and contacted experts. Studies evaluating the diagnostic accu...
HIV infection is commonly diagnosed by detection of antibodies (anti-HIV) by ELISA or agglutination. Reactive results are confirmed by western blot (immunoblot) or further specific tests such as competitive ELISA, which, when evaluated quantitatively, allow the differentiation of HIV types and partially subtypes. Detection of infection of newborn babies, characterisation of individual strains f...
Viral hepatitis claims one million lives each year. Scaling up treatment for hepatitis B and C in resource-limited settings is not possible without access to reliable diagnostic tools. This article gives an overview of current technologies and the pipeline for easy-to-use assays for serological and virological analyses, which can be performed at the site of patient care ('point-of-care assays')...
Introduction: The gold standard for diagnosis of coronavirus disease 2019 (COVID-19) is detecting severe acute respiratory syndrome 2 (SARS-CoV-2) by reverse transcription polymerase chain reaction (RT-PCR), which expensive, time-consuming and may result in false-negative results. Serological tests can be employed RT-PCR negative patients, contact tracing, determining the probability protection...
