Objective Third generation anti-HCV ELISA is currently recommended for the diagnosis of HCV infection. We determined its specificity in voluntary blood donors (VBDs) and patients with chronic liver disease (CLD) in relation to confirmatory line immunoassay (LIA) and reverse transcription polymerase chain reaction (RT-PCR). Material and Methods: 1926 serum samples of VBDs and 16 HCV related CLD ...

in this study a nested-pcr assay was optimized for detection of two bvdv biotype of nadl strain. a part of 5' non-coding region of virus, 249 bp in size, was amplified in rt-pcr. pcr product was cloned in a ptz57r/t vector and sequencing results confirmed the specificity of the test. internal primers were designed and a 155 bp dna fragment was amplified in nested-pcr. the sensitivity of rt...

Background: To investigate the expression of TNF-α, IL-6, IL-10 in the plasma of patients with lung cancer who received radiation therapy (RT), and to analyze the correlation between these cytokines and radiation pneumonitis (RP). Materials and Methods: Patients with lung cancer who received 3D-CRT in our hospital were prospectively evaluated. Circulating cytokine levels were measured wit...

Antigen-coated plate enzyme-linked immunosorbent assay (ACP-ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the presence seed transmissibility of bean common mosaic virus-blackeye cowpea (BCMV-BICM) in farm- retained lots obtained from 46 locations, including markets farms major growing areas Ashanti Brong Ahafo regions Ghana. In growout tests, virus symp...

beet necrotic yellow vein benivirus (bnyvv) as one of the most important virues of sugar beet is the causal agent of rhizomania. bnyvv, as a type member of genus benyvirus has four types a, b, p and j, that are restricted to specific geographic areas. types a and b are similar in pathogenicity, but p and j types that have rna5 are more aggressive. these types cannot be distinguished serological...

Abstract Background Dengue virus (DENV) infection is increasingly common in southern China and can be transmitted through blood transfusion but not currently part of donor screening throughout the region. We assessed DENV prevalence among donors at Xishuangbanna Blood Center, Yunnan, to support development strategies. Methods samples were collected randomly between June 2019 August 2019. These ...

BACKGROUND Foot-and-mouth disease (FMD) is an economically important and highly contagious viral disease that affects cloven-hoofed domestic and wild animals. Virus isolation and enzyme-linked immunosorbent assay (ELISA) are the gold standard tests for diagnosis of FMD. As these methods are time consuming, assays based on viral nucleic acid amplification have been developed. RESULTS A previou...
