| a novel pestivirus associated with deaths in pyrenean chamois (rupicapra pyrenaica pyrenaica). | during investigations into recent population decreases in pyrenean chamois (rupicapra pyrenaica pyrenaica) 21 animals found dead or dying were necropsied. immunohistochemistry revealed the presence of a pestivirus in organs from two of the 21 chamois. from one of these animals a pestivirus was isolated from the spleen, skin and serum. the virus had better growth in ovine than in bovine cells and was neutralized most effectively by an anti-border disease virus (bdv) reference antiserum. using pan ... | 2004 | 15557238 |
| molecular identification of a new pestivirus associated with increased mortality in the pyrenean chamois (rupicapra pyrenaica pyrenaica) in spain. | pestivirus infection was identified in 16 of 17 chamois during an outbreak of a previously unreported disease in pyrenean chamois (rupicapra pyrenaica pyrenaica) in northeastern spain in 2001-02. by analysis of the 5' noncoding regions of the virus, we assigned it to the border disease virus cluster with pairwise similarity values ranging from 82.1% to 88.1%. it will be important to investigate the association of this pestivirus with disease in pyrenean chamois. | 2004 | 15650103 |
| detection of a newly described pestivirus of pyrenean chamois (rupicapra pyrenaica pyrenaica) in france. | a pestivirus was detected and characterized in chamois (rupicapra pyrenaica pyrenaica) originating from the french part of the pyrenees. phylogenetic analysis of the pestivirus was done on the basis of a fragment from the 5' noncoding region including 22 published nucleotide sequences of different pestivirus strains. our strain was grouped within the clade of border disease viruses (bdv). however, it had an intermediate position between clade bdv and classical swine fever viruses representing a ... | 2005 | 16244072 |
| transmission of a pestivirus infection in a population of pyrenean chamois. | outbreaks of a previously unrecorded disease have recently affected pyrenean chamois (rupicapra pyrenaica pyrenaica) populations across the mountain range. a pestivirus was hypothesized to be the cause of this emerging disease and this type of virus can cross the species barrier and be transmitted to or from wildlife. using an epidemiological survey conducted from 1995 to 2004 at orlu, france, we characterized the virus and analyzed its transmission. a phylogenetic analysis of viral sequences an ... | 2007 | 17092662 |
| genetic and antigenic typing of border disease virus isolates in sheep from the iberian peninsula. | a selection of 10 pestiviruses isolated from sheep from the iberian peninsula from 2001 to 2004 was characterised at the molecular level. the 5' untranslated region (5'-utr) and n(pro)-coding gene were amplified by the reverse transcription-polymerase chain reaction (rt-pcr) and sequenced directly from purified products. all isolates were also typed antigenically with a panel of monoclonal antibodies (mabs) raised against representative isolates of the four recognised pestivirus species. the gen ... | 2007 | 17126573 |
| border disease virus among chamois, spain. | approximately 3,000 pyrenean chamois (rupicapra pyrenaica pyrenaica) died in northeastern spain during 2005-2007. border disease virus infection was identified by reverse transcription-pcr and sequencing analysis. these results implicate this virus as the primary cause of death, similar to findings in the previous epizootic in 2001. | 2009 | 19239761 |
| bluetongue virus serotype 1 in wild ruminants, france, 2008-10. | the persistence of bluetongue virus serotype 1 (btv-1) circulation was evaluated in red deer (cervus elaphus), roe deer (capreolus capreolus), mouflons (ovis ammon), and pyrenean chamois (rupicapra pyrenaica pyrenaica) sampled during two hunting seasons between september 2008 and february 2010 in the east pyrenean mountains, france. the prevalence of btv antibody in red deer was high and not significantly different between the two hunting seasons (50.9% and 49.6%, respectively). the prevalence o ... | 2012 | 23060507 |
| spatial and temporal phylogeny of border disease virus in pyrenean chamois (rupicapra p. pyrenaica). | border disease virus (bdv) affects a wide range of ruminants worldwide, mainly domestic sheep and goat. since 2001 several outbreaks of disease associated to bdv infection have been described in pyrenean chamois (rupicapra pyrenaica pyrenaica) in spain, france and andorra. in order to reconstruct the most probable places of origin and pathways of dispersion of bdv among pyrenean chamois, a phylogenetic analysis of 95 bdv 5'untranslated sequences has been performed on chamois and domestic ungulat ... | 2016 | 28033381 |
| the european hare (lepus europaeus) as a potential wild reservoir for ruminant pestiviruses. | ruminant pestiviruses cause important economic losses in livestock and the epidemiological role of free-ranging sympatric wildlife is of special interest for the implementation of pestivirus eradication plans. moreover, the emergence of high mortality outbreaks of pestivirus in pyrenean chamois (rupicapra pyrenaica pyrenaica) since 2001 in the border between spain and france has increased the value of knowing the hosts that role pestivirus infection. in the present study, pestivirus infection wa ... | 2016 | 27544252 |
| border disease virus: an exceptional driver of chamois populations among other threats. | though it is accepted that emerging infectious diseases are a threat to planet biodiversity, little information exists about their role as drivers of species extinction. populations are also affected by natural catastrophes and other pathogens, making it difficult to estimate the particular impact of emerging infectious diseases. border disease virus genogroup 4 (bdv-4) caused a previously unreported decrease in populations of pyrenean chamois (rupicapra pyrenaica pyrenaica) in spain. using a po ... | 2015 | 26733943 |
| surveillance of border disease in wild ungulates and an outbreak in pyrenean chamois (rupicapra pyrenaica pyrenaica) in andorra. | the principality of andorra is surrounded by areas in which pyrenean chamois (rupicapra pyrenaica pyrenaica) populations were severely affected by infection with border disease virus (bdv) which caused disease outbreaks between 2001 and 2009. nevertheless, the andorran chamois populations were not affected during this period. in light of the severe impact of bdv on several of the neighboring pyrenean chamois populations, we monitored local andorran populations in an effort to detect pestivirus a ... | 2012 | 23060503 |
| polymorphisms at mhc class ii drb1 exon 2 locus in pyrenean chamois (rupicapra pyrenaica pyrenaica). | chamois (rupicapra spp.) are mountain ungulates from southern and central europe and the near east. a newly reported border disease virus (bdv) has affected the easternmost populations of pyrenean chamois, leading to a dramatic population decrease that may drive to genetic variability loss. the major histocompatibility complex (mhc) is a sensitive marker for genetic variation of populations: polymorphism on the mhc genes is affected both by pathogens and population dynamics and it is ecologicall ... | 2012 | 22425496 |
