BACKGROUND At least two genetically different porcine epidemic diarrhea virus (PEDV) strains have been identified in the United States (U.S. PEDV prototype and S-INDEL-variant strains). The current serological assays offered at veterinary diagnostic laboratories for detection of PEDV-specific antibody are based on the U.S. PEDV prototype strain. The objectives of this study were: 1) isolate the...
Epizootic haemorrhagic disease virus (EHDV) infects wild ruminants, causing a frequently fatal haemorrhagic disease. However, it can also cause bluetongue-like disease in cattle, involving significant levels of morbidity and mortality, highlighting a need for more rapid and reliable diagnostic assays. EHDV outer-capsid protein VP2 (encoded by genome-segment 2 [Seg-2]) is highly variable and rep...
The hepatitis C virus (HCV) infects more than 200 million people globally, with increasing incidence, especially in developing countries. HCV infection frequently progresses to chronic liver disease, creating a heavy economic burden on resource-poor countries and lowering patient quality of life. Effective HCV diagnosis, treatment selection, and treatment monitoring are important in stopping di...
BACKGROUND The inefficiency of the current tachyzoite antigen-based serological assays for the serodiagnosis of Toxoplasma gondii infection mandates the need for acquirement of reliable and standard diagnostic reagents. Recently, epitope-based antigens have emerged as an alternative diagnostic marker for the achievement of highly sensitive and specific capture antigens. In this study, the diagn...
Abstract The humoral immune response to SARS-CoV-2 is a benchmark for immunity and detailed analysis required understand the manifestation progression of COVID-19, monitor seroconversion within general population, support vaccine development. majority currently available commercial serological assays only quantify antibody against individual antigens, limiting our understanding response. To ove...
Helicobacter pylori infection is endemic in Korea, and serology testing is widely performed. The aim of this study was to validate and compare the diagnostic accuracy of Korean and Western serological assays for H. pylori detection in Korean adults. The 114 Korean adults who visited our centre over a 6-month period for the evaluation of H. pylori infection using the urea breath test (UBT) were ...
Validation is a process that determines the fitness of an assay, which has been properly developed, 6 optimised and standardised, for an intended purpose. Validation 8 includes estimates of the analytical and diagnostic performance 10 characteristics of a test. In the context of this chapter, an assay that 12 has completed the first three stages of the validation pathway (see 14 Figure 1 below)...
