A rapid and sensitive reverse transcription polymerase chain reaction (RT-PCR) and nested-PCR were used to detect bovine viral diarrhea virus 1 (BVDV-1) in bull semen. Selected primers could amplify a part of the 5´UTR of the BVDV genome. A 294 bp DNA fragment was amplified and specificity of the results was confirmed by direct sequencing of the PCR product. Prior to RNA extraction, the seminal...
VirOligo is a database of virus-specific oligonucleotides. The VirOligo database consists of two tables, Common data and Oligo data. The Oligo data table contains PCR primers and hybridization probes used for detection of viral nucleic acids and the Common data table contains the experimental conditions used in their detection. Each oligonucleotide entry contains links to PubMed, GenBank, NCBI ...
Aim The study was designed to measure the seroprevalence of viral and bacterial diseases: Infectious bovine rhinotracheitis, bovine viral diarrhea, bovine leukemia, bovine parainfluenza, bovine respiratory syncytial disease, brucellosis, and paratuberculosis among bovine of Himachal Pradesh during the year 2013-2015. Materials and Methods The serum samples were collected from seven districts ...
Genotypes and subgenotypes of bovine viral diarrhea virus (BVDV) field isolates from Japan, Germany and the United States of America (USA) were identified, and the prevalent pattern of BVDV in individual countries was estimated genetically. Subgenotypes were determined based on phylogenetic analyses of nucleotide sequences of a part of the E2-coding gene of BVDV. Forty-five, 61 and 56 BVDV stra...
زمـیـنــه مــطــالـعــه: دو بـیـمــاری اسـهــال ویــروســی گـاوان (Bovine viral diarrhea, BVD) و رینـوتـراکئیـت عفـونـی گـاوان (Infectious bovine rhinotracheitis, IBR)، از جمله عوامل تحمیل خسارات اقتصادی قابل توجه در صنعت دامپروری ایران میباشد. هدف: با توجه به فقدان واکسن تولید داخل، ضروری است، اثربخشی واکسنهای تجاری وارداتی بررسی شود. روش کار: کارآزمایی شاهددار تصادفی شده و کور با هدف تعیی...
Background: To further minimize transmission risk of blood-borne viral and prion diseases, manufacturers of therapeutic animalor human-derived proteins have implemented improved in-process pathogen-removal procedures. Objectives: To evaluate removal of transmissible spongiform encephalopathy agents (prions) and viruses using Omega 100K VR membrane filtration system (Pall Filtron, Northborough, ...
Two strains of Bovine viral diarrhea virus 2 (BVDV-2) were isolated from calves in northern Italy. Variations in the 5'-untranslated region (UTR) of the genome were studied by primary structure alignment and neighbor-joining method based phylogenetic tree analyses and by palindromic nucleotide substitutions at the three variable loci in the 5'-UTR. Genetic analysis indicated their appurtenance ...
A total of 85 beef heifers were used to determine if vaccination with a modified-live virus (MLV) vaccine containing bovine viral diarrhea virus types 1 and 2 (BVDV1 and BVDV2) approximately 1 year prior to challenge with virulent BVDV1b and BVDV2a will protect against fetal infection. BVDV1 and BVDV2 seronegative heifers were vaccinated at approximately 15 months of age with a commercially ava...
abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...
