To date information on rabbit haemorrhagic disease virus (RHDV) in Spain and Portugal has been scarce, although the disease is endemic and continues to have a considerable impact on species conservation and hunting industry. We analysed RHDVs obtained between 1994 and 2007 at different geographic locations in Portugal (40 samples), Spain (3 samples) and(More)
Since summer 2010, numerous cases of Rabbit Haemorrhagic Disease (RHD) have been reported in north-western France both in rabbitries, affecting RHD-vaccinated rabbits, and in wild populations. We demonstrate that the aetiological agent was a lagovirus phylogenetically distinct from other lagoviruses and which presents a unique antigenic profile.(More)
Rabbit Hemorrhagic disease virus (RHDV), a calicivirus of the Lagovirus genus, and responsible for rabbit hemorrhagic disease (RHD), kills rabbits between 48 to 72 hours post infection with mortality rates as high as 50-90%. Caliciviruses, including noroviruses and RHDV, have been shown to bind histo-blood group antigens (HBGA) and human non-secretor(More)

A duck parvovirus (DPV) isolated from muscovy ducks during the epizootic in France in 1989 was purified from inoculated allanto-amniotic fluids by CsCl density gradient centrifugation and characterized. Full and empty non-enveloped icosahedral viral particles were observed banding at densities of 1.39 to 1.42 and 1.38 respectively, with a diameter of 22 to(More)
The gene encoding the muscovy duck parvovirus (DPV)-strain 89384 capsid proteins VP2 and VP3 was cloned in a baculovirus expression system and expressed in insect cells. The recombinant proteins were found to react with specific anti-DPV serum by Western blotting and to be located in the nucleus of insect cells (Sf9) as shown by immunofluorescence. Empty(More)
Lagovirus is an emerging genus of Caliciviridae, which includes the Rabbit Hemorrhagic Disease Virus (RHDV) of rabbits and the European brown hare syndrome virus (EBHSV) of hares that cause lethal hepatitis. In 2010, a new RHDV related virus (RHDV2) with a unique genetic and antigenic profile and lower virulence was identified in France in rabbits. Here we(More)
Although muscovy duck reovirus (DRV) shares properties with the reovirus isolated from chicken, commonly named avian reovirus (ARV), the two virus species are antigenically different. Similar to the DRV sigmaB-encoded gene (1201 bp long) previously identified, the three other double-stranded RNA small genome segments of DRV have been cloned and sequenced.(More)
Developing vaccines for livestock provides researchers with the opportunity to perform efficacy testing in the natural hosts. This enables the evaluation of different strategies, including definition of effective antigens or antigen combinations, and improvement in delivery systems for target antigens so that protective immune responses can be modulated or(More)
The data were recorded during a Rabbit haemorrhagic disease outbreak that occurred in France in 2001 in a wild population of rabbits that we have been monitoring since 2000. These data suggested the existence of non-protective antibodies due to a putative RHDV-like virus. Twenty-one blood and 22 liver samples were taken from the 26 corpses of recently dead(More)
