| pestivirus infections in ruminants other than cattle. | pestiviruses infect a wide range of domestic, captive and free-living ruminants. among domestic livestock, border disease virus is a well recognised cause of an important congenital disease of sheep in virtually all sheep-rearing countries of the world. the clinical signs, pathogenesis, diagnosis, epidemiology and control of this disease are described in detail. one natural outbreak of border disease in domestic goats has been described and there is serological and virological evidence that pest ... | 1990 | 1966719 |
| genetic and antigenic characterization of an atypical pestivirus isolate, a putative member of a novel pestivirus species. | the genus pestivirus within the family flaviviridae currently consists of four different main species: classical swine fever virus, bovine viral diarrhea virus types 1 and 2 and border disease virus. a fifth tentative species is represented by an isolate from a giraffe. in this study, a completely new pestivirus, isolated from a batch of fetal calf serum that was collected in brazil, is described. it is proposed that the isolate d32/00_'hobi' may constitute a novel sixth pestivirus species, beca ... | 2004 | 15557237 |
| numerical taxonomy of the genus pestivirus based on palindromic nucleotide substitutions in the 5' untranslated region. | the palindromic nucleotide substitutions (pns) at the three variable loci (v1, v2 and v3) in the 5' untranslated region (utr) of pestivirus rna have been considered for taxonomical segregation of species, through the evaluation of 430 genomic sequences. on the basis of qualitative and quantitative secondary structure characteristics, six species have been identified: bovine viral diarrhea virus 1 (bvdv-1), bovine viral diarrhea virus 2 (bvdv-2), classical swine fever virus (csfv), border disease ... | 2007 | 17719098 |
| phylogeny, classification and evolutionary insights into pestiviruses. | the genus pestivirus comprises four established species: bovine viral diarrhoea viruses 1 (bvdv-1) and 2 (bvdv-2), border disease virus (bdv), and classical swine fever virus (csfv); and a tentative species, pestivirus of giraffe. additional pestiviruses have been identified and suggested for recognition as novel subgroups/species. to achieve a reliable phylogeny as the basis for classification of pestiviruses, a molecular dataset of 56 pestiviruses and 2089 characters, comprising the 5'utr, com ... | 2009 | 19167739 |
| complete genomic sequence of a border disease virus isolated from pyrenean chamois. | this report describes the full-length genome sequence of the pestivirus strain h2121 which was recently isolated from pyrenean chamois and typed as border disease virus (bdv) genotype 4. comparison with full-length genomic sequences of the approved pestivirus species bovine viral diarrhea virus-1 (bvdv-1), bvdv-2, bdv, and classical swine fever virus, the tentative species represented by strain giraffe-1, as well as the atypical pestivirus strain th/04_khonkaen confirmed that the chamois pestivi ... | 2010 | 20638945 |
| species characterization in the genus pestivirus according to palindromic nucleotide substitutions in the 5'-untranslated region. | the palindromic nucleotide substitutions (pns) at the three variable loci (v1, v2 and v3) in the 5'-untranslated region (utr) of the pestivirus genome have been considered for taxonomical segregation of the species, through the evaluation of 534 strains. on the basis of qualitative and quantitative secondary structure characteristics, species have been identified within the genus, determining genetic distances between species isolates, clarifying borderline and multirelated sequences, and charac ... | 2011 | 21514324 |
| ligand-responsive rna mechanical switches. | ligand-responsive rna mechanical switches represent a new class of simple switching modules that adopt well-defined ligand-free and bound conformational states, distinguishing them from metabolite-sensing riboswitches. initially discovered in the internal ribosome entry site (ires) of hepatitis c virus (hcv), these rna switch motifs were found in the genome of diverse other viruses. although large variations are seen in sequence and local secondary structure of the switches, their function in vi ... | 2015 | 26158858 |
| emerging pestiviruses infecting domestic and wildlife hosts. | until the early 1990 s there were just three recognized species in the pestivirus genus, bovine viral diarrhea virus (bvdv), border disease virus (bdv) and classical swine fever virus (csfv). subsequently bvdv were divided into two different species, bvdv1 and bvdv2 and four additional putative pestivirus species have been identified, based on phylogenetic analysis. the four putative pestivirus specices, listed in chronological order of published reports, are giraffe (isolated from one of severa ... | 2015 | 26050572 |
| numerical taxonomy of the genus pestivirus: new software for genotyping based on the palindromic nucleotide substitutions method. | the genus pestivirus from the family flaviviridae is represented by four established species; bovine viral diarrhea virus 1 (bvdv-1); bovine viral diarrhea virus 2 (bvdv-2); border disease virus (bdv); and classical swine fever virus (csfv); as well a tentative species from a giraffe. the palindromic nucleotide substitutions (pns) in the 5' untranslated region (utr) of pestivirus rna has been described as a new, simple and practical method for genotyping. new software is described, also named pn ... | 2013 | 23684846 |
