Abstract Background All modern gastrointestinal (GI) testing laboratories face a similar challenge: How to test panel of analytes from the same stool or plasma/serum sample and deliver clinically accurate results in timely fashion. GI are tested primarily on ELISAs that while accurate, manual ELISA is time-consuming work intensive. In this study, we utilize automated ALPCO five-plex assay (Auto...

HBsAg is one of the earliest markers that appear in the blood following infection with Hepatitis B virus (HBV). This infection of the liver is transmitted by homosexual or heterosexual activity, blood borne exposure, mother infant, close personal contact and by intake of contaminated water and food products. In the HBV infected people, the virus persists for the rest of their lives and can be p...

ABSTRACT: Bovine viral diarrhea virus (BVDV) is a highly infectious pathogen that affects bovines worldwide leading to great economic impact. Although Brazil has the largest commercial cattle population throughout world and an increasing buffalo breeding industry, country no control or eradication program for BVDV. In this perspective, aim of study was evaluate occurrence BVDV in buffaloes from...

The aim of this study was to estimate the diagnostic value of different commercially available ELISA kits for the detection of bluetongue virus (BTV) antibodies in infected and vaccinated animals. The relative specificity of ELISA kits was evaluated using a panel of sera originating from healthy cattle, never vaccinated nor exposed to BTV. All ELISA kits applied had a high relative specificity ...

Undifferentiated nasopharyngeal carcinoma (NPC; WHO type III) is 100% associated with Epstein-Barr virus (EBV) infection and the fourth most prevalent cancer in Indonesian males. Therapy failure is high, since most patients come to the hospital at an advanced stage of disease. Screening for early-stage NPC is needed. Here, a simple and economical two-step enzyme-linked immunosorbent assay (ELIS...

BACKGROUND Glucose-dependent insulinotropic peptide (GIP) is an incretin peptide secreted by intestinal K cells that stimulates insulin secretion in a glucose-dependent manner. It is secreted as an active, intact 42-amino acid peptide GIP(1-42), which is rapidly degraded by dipeptidyl peptidase 4 to GIP(3-42), which is inactive. There is currently no described monoclonal antibody-based sandwich...

In order to elucidate the usefulness of various tests in the early course of dengue infection, in terms of diagnosis and correlation with clinical severity, blood specimens were collected every 48 hours on 3 occasions from patients with clinical suspicion of dengue infection with fever for less than 4 days. Viral isolation was attempted by mosquito inoculation (MI), tissue culture inoculation (...
