| experimental infection with chamois border disease virus causes long-lasting viraemia and disease in pyrenean chamois (rupicapra pyrenaica). | since 2001, severe outbreaks of disease associated with border disease virus (bdv) infection have been reported in the pyrenean chamois. the disease is characterized by variable degrees of cachexia, alopecia and neurological manifestations prior to death. the aim of this study was to investigate this disease under experimental conditions. to assess viral virulence, humoral immune response, dissemination and probable routes of transmission, seven chamois (five seronegative and two seropositive to ... | 2011 | 21775580 |
| two different epidemiological scenarios of border disease in the populations of pyrenean chamois (rupicapra p. pyrenaica) after the first disease outbreaks. | since 2001 several outbreaks of a new disease associated with border disease virus (bdv) infection have caused important declines in pyrenean chamois (rupicapra pyrenaica) populations in the pyrenees. the goal of this study was to analyze the post-outbreak bdv epidemiology in the first two areas affected by disease with the aim to establish if the infection has become endemic. we also investigated if bdv infected wild and domestic ruminants sharing habitat with chamois. unexpectedly, we found di ... | 2012 | 23251417 |
| 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 |
| the two sides of border disease in pyrenean chamois (rupicapra pyrenaica): silent persistence and population collapse. | in 2001, border disease virus (bdv) was identified as the cause of a previously unreported disease in pyrenean chamois (rupicapra pyrenaica) in spain. since then, the disease has caused a dramatic decrease, and in some cases collapse, of chamois populations and has expanded to nearly the entire distribution area in the pyrenees. chamois bdv was characterized as bdv-4 genotype and experimental studies confirmed that it was the primary agent of the disease. the infection has become endemic in the ... | 2015 | 26050575 |
| experimental infection of pregnant pyrenean chamois (rupicapra pyrenaica) with border disease virus subtype 4. | border disease virus (bdv) causes high mortality in pyrenean chamois (rupicapra pyrenaica) on the french and spanish sides of the pyrenees mountains. we investigated the pathology induced by bdv in pregnant chamois via experimental infection. three females were inoculated during the second third of pregnancy with a bdv-4 subgroup strain isolated from a wild pyrenean chamois during an acute epizootic. a fourth pregnant chamois and one nonpregnant ewe were kept as negative controls. animals were m ... | 2013 | 23307372 |
| 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 |
| host and viral traits predict zoonotic spillover from mammals. | the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ... | 2017 | 28636590 |
| global mammal parasite database version 2.0. | illuminating the ecological and evolutionary dynamics of parasites is one of the most pressing issues facing modern science, and is critical for basic science, the global economy, and human health. extremely important to this effort are data on the disease-causing organisms of wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, and fungi). here we present an updated version of the global mammal parasite database, a database of the parasites of wild ungulates (artioda ... | 2017 | 28273333 |
