Bovine viral diarrhoea virus (BVDV) is an economically important pathogen of cattle that is ubiquitously distributed worldwide. In this study, cattle were immunized by intramuscular injections with plasmid DNA expressing the BVDV type 1 major glycopr

The E2 protein of bovine viral diarrhea virus (BVDV) is a major viral glycoprotein and an attractive target for BVDV vaccines. Three replication defective recombinant adenoviruses expressing the BVDV/E2 protein (rAds/E2) were constructed. Two contain

Two replication-defective human adenovirus recombinants encoding the NS3 protein (p80) of bovine viral diarrhea virus (BVDV) under the control of a modified adenovirus major later promoter (BM5), rAdBM5/NS3, and human cytomegalovirus promoter (CMV5),

Variation in the third base of a codon hampers genotypic characterization, particularly of RNA viruses. Some restriction endonucleases, however, have a recognition site with a variable base at the third position and will always cleave when a certain

A reverse transcriptase and polymerase chain reaction (RT-PCR)-based assay for G-typing of bovine rotaviruses (BRV) was compared with a monoclonal antibody-based immunoassay (MAbs-ELISA) in the characterization of BRV field strains obtained from calv

The 5' untranslated region (UTR) of several bovine viral diarrhea virus (BVDV) isolates from the severe Quebec outbreak was amplified by polymerase chain reaction (PCR) and sequenced. Sequences revealed the loss, for the BVDV type II isolates, of an

An enzyme-linked immunosorbent assay (ELISA) for the detection of transmissible gastroenteritis virus (TGEV) and porcine respiratory coronavirus (PRCV) was developed. A bovine TGEV-specific polyclonal antibody was purified by affinity chromatography

This study describes, for the first time, the production and use of an "internal-image" anti-idiotypic monoclonal antibody (MAb) to elicit a rotavirus-specific antibody response. An immunoglobulin G2a MAb, designated RQ31 (MAb1), specific for the out

The specificity of Staphylococcus aureus and protein A-Sepharose (PA-S) were compared in the radioimmunoprecipitation assay for the characterization of monoclonal antibodies (mAbs) against rotavirus proteins. Five mAbs directed against bovine rotavir

Bovine rotavirus proteins were analysed by a panel of monoclonal antibodies. Glycosylated epitopes were identified on both inner and outer capsid proteins (VP6 and VP7 respectively). VP7 possessed a periodate insensitive epitope which was, however, s
