Millions of domestic and wild European rabbits (Oryctolagus cuniculus) have died in Europe, Asia, Australia and New Zealand during the past 17 years following infection by Rabbit haemorrhagic disease virus (RHDV). This highly contagious and deadly disease was first identified in China in 1984. Epidemics of RHDV then radiated across Europe until the virus(More)
With the exception of virus strains Ashington and RCV, other recognised strains of Rabbit haemorrhagic disease virus (RHDV) share relatively close genetic homology. Using serology and phylogenetic analysis, we have identified a third disparate virus lineage in healthy rabbits on Lambay Island off the east coast of Eire, where disease due to RHDV has never(More)
Because Rabbit haemorrhagic disease virus (RHDV) is highly pathogenic for rabbits, farmers illegally introduced it as a bio-control agent onto New Zealand farms in 1997. The virus was dispersed rapidly, initially causing high fatality rates in rabbits. Nevertheless, many survived and these surviving rabbits have been investigated for evidence of infection(More)
Rabbit haemorrhagic disease virus emerged in China in 1984, and has killed hundreds of millions of wild rabbits in Australia and Europe. In the UK there appears to be an endemic non-pathogenic strain, with high levels of seroprevalence being recorded, in the absence of associated mortality. Using a seasonal, age-structured model we examine the hypothesis(More)
Adult wild rabbits from the southern UK, previously unexposed to rabbit haemorrhagic disease (RHD), were experimentally challenged with a UK strain of the virus in laboratory conditions. Initial serum antibodies were measured by an haemagglutination inhibition test and all seropositive rabbits, with reciprocal titres > 10, were protected against fatal(More)
Rabbit haemorrhagic disease virus (RHDV) has killed many millions of wild rabbits in Europe and Australia, but has had little impact in the United Kingdom, despite outbreaks having occurred since 1994. High seroprevalence detected in the absence of associated mortality had suggested the presence of an endemic non-pathogenic strain which may be 'protecting'(More)
Myxomatosis now kills a much smaller proportion of rabbit populations than in the past, while remaining an important regulatory factor, as shown experimentally. On two separate occasions, experimental reduction of the prevalence of the disease (by reducing infestations of the main vector, the rabbit flea) led to significant increases in numbers of rabbits(More)
The common dormouse is a European protected species that is considered at risk during forest management operations in the UK. Historically, they were believed to exist principally in scrub and broadleaved woodlands, especially hazel coppice, but recent evidence has shown that they are present in some conifer sites at low density. Operations to restore(More)
