N2 - Background: Only one strain (the Czech CAPM-v351) of rabbit haemorrhagic disease virus (RHDV) has been released in Australia and New Zealand to control pest populations of the European rabbit O. cuniculus. Antigenic variants of RHDV known as RHDVa strains are reportedly replacing RHDV strains in other parts of the world, and Australia is currently investigating the usefulness of RHDVa to complement rabbit biocontrol efforts in Australia and New Zealand. RHDV efficiently kills adult rabbits but not rabbit kittens, which are more resistant to RHD the younger they are and which may carry the virus without signs of disease for prolonged periods. These different infection patterns in young rabbits may significantly influence ...

During the past 50 years two readily distinguishable rabbit-specific diseases caused by Myxoma virus (MYXV) and Rabbit haemorrhagic disease virus (RHDV) respectively, have decimated wild rabbit populations worldwide. Combined with the use of these viruses as biocontrol agents, the consequences for farming, commercial rabbit breeding and rare habitat conservation dependent on rabbit grazing, have been both positive and negative. Moreover, rare predators that rely on rabbits as a food resource, and even hunters, have suffered the consequences of rabbit populations being affected by one or other of these viruses. Rabbit haemorrhagic disease virus was first identified after thousands of domestic rabbits died suddenly in China in 1984. Similar epidemics subsequently occurred in other regions of Asia, the Middle East, Europe and North America, suggesting that the virus had dispersed widely following its emergence in China. However, the discovery that RHDV had circulated apparently harmlessly for many ...

N2 - Rabbit Haemorrhagic Disease Virus (RHDV) was introduced into Australia in 1995 as a biological control agent against the wild European rabbit (Oryctolagus cuniculus). We evaluated its evolution over a 16-year period (1995-2011) by examining 50 isolates collected throughout Australia, as well as the original inoculum strains. Phylogenetic analysis of capsid protein VP60 sequences of the Australian isolates, compared with those sampled globally, revealed that they form a monophyletic group with the inoculum strains (CAPM V-351 and RHDV351INOC). Strikingly, despite more than 3000 rereleases of RHDV351INOC since 1995, only a single viral lineage has sustained its transmission in the ...

Rabbit haemorrhagic disease virus (RHDV) belongs to the family Caliciviridae and is the etiological agent of the haemorrhagic disease, also known as rabbit plague. Its genome is a linear single-stranded (ss) RNA of 7437 nucleotides and the capsid is built from a single structural protein VP60. In connection with the discovery of new RHDV strains, there is a constant need to investigate the genetic variation of this virus and perform phylogenetic analyses which may show the evolutionary relationships among the RHDV strains. Studies on the divergence of RHDV have shown that it is genetically quite stable, although recent observations indicate that some new RHDV strains, significantly different from the original RHDV subtype and the new RHDVa subtype, are appearing. These latest findings suggest that a new group of RHDV strains has evolved. The present review summarizes the current knowledge on the genetic variation and the latest achievements in phylogenetic analyses of RHDV strains isolated in ...

We carried out an experimental study to determine the serological response against myxoma virus (MV) and rabbit hemorrhagic disease virus (RHDV) in wild rabbits using commercial vaccines. Seroconversion against MV ranged between 72.7% and 97.2% in animals vaccinated by subcutaneous and intradermal route, respectively, whereas between 75.0% and 77.8% of the animals presented antibodies against RHDV after inoculation with subcutaneous and intradermal vaccines, respectively. Regardless of the inoculation route, vaccination against MV resulted in a significant increase of seropositivity 5 days post-vaccination (dpv), which did not occur in animals vaccinated against RHDV. Furthermore, seroconversion against MV was significantly higher and faster in intradermally vaccinated rabbits as compared to those inoculated subcutaneously due to either the route of application and/or the type of vaccine used. The results indicated that vaccination significantly increased the prevalence of antibodies against MV ...

Rabbit haemorrhagic disease (RHD), also known as rabbit calicivirus disease (RCD) or viral haemorrhagic disease (VHD), is a highly infectious and often fatal disease that affects wild and domestic rabbits of the species Oryctolagus cuniculus. The infectious agent responsible for the disease is rabbit haemorrhagic disease virus (RHDV), or rabbit calicivirus (RCV), genus Lagovirus of the family Caliciviridae. The virus infects only rabbits, and has been used in some countries to control rabbit populations. RHD first appeared in the Winter of 1983 in Jiangsu Province of the Peoples Republic of China. It was first isolated and characterized by S.J. Liu et al. in 1984. The Chinese outbreak was spread by the angora rabbit, which had originated in Europe. Fourteen million domesticated rabbits died within nine months in the outbreak. In 1984 the virus that caused the disease was identified. The virus spread westward and reached Europe in 1988. The virus has since appeared in Mexico, Cuba, Australia, ...

Wildlife officials recently announced outbreaks of Rabbit Hemorrhagic Disease Virus Type 2 (RHDV2) ravaging Texas, New Mexico, Colorado, Arizona and California. The U.S. Department of Agriculture (USDA) deems RHDV2 as seriously contagious and nearly always fatal amongst domestic and wild rabbit species and their close relatives, hares and pikas. RHDV2 is not zoonotic, so it wont infect livestock, pets or humans, asserts the California Department of Fish & Wildlife (CDFW) . Still, Texas Parks & Wildlife (TPW) advise against pets consuming rabbit carcasses. Rabbit Hemorrhagic Disease Virus (RHDV) is the viral agent causing rabbit hemorrhagic disease (RHD). Science Direct says RHDV belongs in the calicivirus family, which infects many animals including pigs, cattle, cats and even humans. Norovirus, for example, is a human calicivirus. But humans seem unaffected by RHDV. Related: Whats causing the decline in monarch butterfly populations? There are two worrisome strains of RHDV - RHDV1 and RHDV2. ...

Disease Does Not Affect People, Pets, Livestock. Texas Parks and Wildlife Department (TPWD) has received test results confirming that Rabbit Hemorrhagic Disease (RHD) was diagnosed in a wild black-tailed jackrabbit in Lubbock County and a wild cottontail rabbit in Hudspeth County. This marks the first confirmed cases of RHD in wild rabbits in Texas and follows the discovery of the disease in domestic rabbits in Hockley County, which was announced in a recent Texas Animal Health Commission news release.. Since March 23, detections of the disease in both wild and domestic rabbits have occurred in New Mexico, Colorado, Arizona and Mexico. There have been reports of mortality events in both wild cottontails (genus Sylvilagus) and jackrabbits (genus Lepus) in El Paso, Hudspeth, Brewster, Terrell, Lubbock and Pecos Counties in Texas.. Rabbit Hemorrhagic Disease (RHD) is a highly contagious viral disease that can affect both domestic and wild rabbit species. This disease is nearly always fatal and ...

Haemagglutination and ELISA tests, and negative contrast electron microscopy, have been used to identify rabbit haemorrhagic disease virus in naturally occurring cases of the disease and in experimentally infected rabbits in the United Kingdom. Haemagglutination tests alone are not satisfactory for the diagnosis because non-haemagglutinating isolates of the virus, otherwise indistinguishable from others, have been found in some outbreaks. Haemagglutination inhibition tests have shown that a proportion of both commercial laboratory and wild rabbits in the UK are seropositive to the virus although they have not been associated with clinical disease. This observation, made previously in other parts of Europe, may indicate the longstanding circulation of a related but non-pathogenic strain of virus. Naturally occurring antibody appears to afford a high degree of protection against experimental challenge with virulent virus.. ...

While RHDV2 is a threat to domestic rabbits, the Game Commission has no involvement with domestic animals. PDA is involved with domestic rabbits to the extent that they are raised and slaughtered for meat and such facilities are not voluntarily consenting to USDA and/or FDA oversight. In addition to PDA, USDA, and FDA, private veterinary practices would also provide some oversight of domestic/pet rabbits. Any questions regarding disease surveillance in domestic rabbits should be directed to those non-Game Commission entities. Veterinary diagnostic laboratories are aware of the issue and any detections of RHDV2 in domestic lagomorphs in PA will be reported to the Game Commission ...

Hello to All Bunny Owners:. There is currently an outbreak of Rabbit Hemorrhagic Disease (RHD) type 2 in Nanimo. The first cases were diagnosed at the beginning of March. A second outbreak has occurred last week and is confirmed to be RHD type 2. RHD is caused by a calicivirus. It is highly contagious and lethal in rabbits. This disease ONLY affects rabbits. There is no threat to humans and other animals including dogs and cats. All rabbit owner should take precautions against this disease. Strict quarantine is recommended and ideally rabbits should be kept indoors if possible. This virus can be spread via direct contact with live or dead rabbits. Also fomites - including contaminated food, bedding water, and also insects, birds and mammals can transmit the virus long distances. The incubation period for Type 2 disease is about 3-9 days. Symptoms of the disease include fever, anorexia, dullness, congestion, collapse and sudden death. The death rate is high with no cure available. Treatment ...

We report a disease outbreak in a Michigan rabbitry of a rabbit calicivirus distinct from the foreign animal disease agent, rabbit hemorrhagic disease virus (RHDV). The novel virus has been designated Michigan rabbit calicivirus (MRCV). Caliciviruses of the Lagovirus genus other than RHDV have not been described in US rabbit populations. The case-fatality rate was 32.5% (65/200). Clinical signs included hemorrhage and sudden death, with hepatic necrosis. Analysis of viral RNA sequence from >95% of the viral genome showed an average similarity of 79% with RHDV. Similarity of the predicted MRCV capsid amino acid sequence ranged from 89.8% to 91.3%, much lower than the 98% amino acid similarity between RHDV strains. Experimentally infected rabbits lacked clinical disease, but MRCV was detected in tissues by PCR. We propose that MRCV primarily causes subclinical infection but may induce overt RHD-like disease under certain field conditions.

Rabbit Hemorrhagic Disease (RHD) is a severe acute viral disease specifically affecting the European rabbit Oryctolagus cuniculus. As the European rabbit is the predominant species of domestic rabbit throughout the world, RHD contributes towards significant losses to rabbit farming industries and endangers wild populations of rabbits in Europe and other predatory animals in Europe that depend upon rabbits as a food source. Rabbit Hemorrhagic Disease virus (RHDV) - a Lagovirus belonging to the family Caliciviridae is the etiological agent of RHD. Typically, RHD presents with sudden death in 70% to 95% of infected animals. There have been four separate incursions of RHDV in the USA, the most recent of which occurred in the state of Indiana in June of 2005. Animal inoculation studies confirmed the pathogenicity of the Indiana 2005 isolate, which caused acute death and pathological changes characterized by acute diffuse severe liver necrosis and pulmonary hemorrhages.

COVID-19 - it could be worse. Mongolian teenager dies of bubonic plague caught from infected marmot. ABC, 15 July. The deadly plague that could devastate the US rabbit population, The Guardian 15 July. The Black Death (Bubonic Plague) active in Europe between 1347 and 1351, killed around 100 -200 million people. In fact, it may have killed half of the entire population of Europe. This pandemic was caused by a bacterium, Yersinia pestis, not a virus.. Like COVID-19, plague transmits via respiratory droplets. However, the Black Deaths march across the planet was enabled by rodents carrying bacteria-infected fleas. Y. pestis partially blocks the guts of fleas. As the fleas feed on a human, they attempt to clear their blocked guts by regurgitating their meal. This effort releases the bacteria into the bite wound. Prior to medical interventions, people infected with the bubonic plague had about a 50 percent chance of death.. Rabbit haemorrhagic disease virus (RHDV) surfaced in the 1980s as a ...

The management of invasive species is carried out by individuals, conservation groups, and government agencies. The Australian Quarantine and Inspection Service is responsible for ensuring that no new species with the potential to become invasive species enter Australia. To raise public awareness, Australian Quarantine has featured Australian celebrity nature lover Steve Irwin on a series of television commercials, with the message Quarantine - Dont mess with it. Several scientific bodies are involved in research for the control of invasive species. The CSIRO has released several successful biological pest control agents and developed chemical agents for pest and weed control. For example, the CSIRO released myxoma virus to control wild rabbits in Australia. Rabbit haemorrhagic disease escaped containment from an Australian Government research facility and spread across Australia. Rabbit hemorrhagic disease was subsequently legalised for the control of wild rabbits. The moth Cactoblastis ...

They additionally have been liberally infecting the species with the Rabbit Calicivirus Disease (RCD) from as far back as 1991 but since the animals have been able to develop immunities to it that has forced them into developing ever new strains of the killer. What thats (the rabbit eradication biological pipeline plan) trying to do is recognize that we have to put out new strains of the rabbit calicivirus at key points, to keep numbers low, rather than just waiting for numbers to bounce back, going into crisis mode and then trying to do what we can, Andreas Glanzig of the Invasive Animals Cooperative Research Centre (IACRC) at the University of Canberra told the ABC on November 25, 2015. (See Rabbit Control Plan Plays the Long Game to Contain Devastating Pest, Protect Threatened Species.)

The outer-coat proteins, VP2 and VP5, of epizootic haemorrhagic disease virus (EHDV) are important for host cell binding during the initiation of infection. They are also known to determine virus serotype. This study presents a complete genetic and phylogenetic analysis of these proteins (and the genes that code for them) to allow comparison of the selective pressures acting on each and the correlation of genetic sequence data with serotype. Accession numbers, gene and protein sizes, ORF positions, G+C contents, terminal hexanucleotides, start and stop codons and phylogenetic relationships are all presented. The results show that VP2 is highly variable, is under great pressure to adapt and can be correlated with serotype. While also variable, VP5 appears to be under less adaptive pressure than VP2 but still shows some correlation with serotype. Seven serotypes of EHDV have been defined in this study, although the results do show that some serotypes are extremely closely related--and highlight ...

Hemorrhagic disease (HD) is an infectious viral disease transmitted by tiny biting flies (often referred to as midges, gnats, or no-see-ums) in the genus Culicoides. HD is caused by two closely related viruses in the genus Obrbivirus, epizootic hemorrhagic disease (EHD) and bluetongue virus. There are 2 subtypes of EHD virus and 5 subtypes of bluetongue in North America. Because disease features produced by these viruses are indistinguishable, a general term, hemorrhagic disease, often is used when the specific virus is unknown. Although EHD and bluetongue virus are infectious to a wide range of wild ruminants, susceptibility varies among species. Clinical disease has been reported in white-tailed deer, mule deer, bighorn sheep, elk, and pronghorn. Antibodies or virus have been detected in bison and mountain goats; however, these infections were not associated with disease. Although large die-offs of HD have not been reported in Arizona, antibodies for the disease have been documented in mule ...

The introduction of European Rabbits to Australia in 1859 was a disaster for several species of native wildlife, such as the Bilby. Within a few years they had spread throughout most of Australia as the mild winters meant they could breed all year round. The use of biological control through the introduction of rabbit-specific viruses, such as Myxomatosis cuniiculi, and more recently Rabbit Haemorrhagic Disease, has proved relatively effective in reducing rabbit numbers to more acceptable levels, however, the forces of natural selection are a constant barrier to a permanent solution and after only 60 years since the first introduction of Myxomatosis to Australia, almost all wild rabbits are completely immune to the disease. If anyone ever needs a good example of evolution in action, this is it!. ...

Thankfully we have a vaccine that is effective for this disease. It is effective for the RHDV1 strains, but may have limited protection for the RHDV2 which currently is not in Alice Springs.

Australias biocontrol programs using Myxoma virus in 1950 and the Rabbit Calicivirus in 1995 have been extremely successful in drastically reducing pest rabbit numbers in Australia. However, there is no status quo in rabbit biocontrol: the virus and rabbits constantly co-evolve, and changes in virus virulence and innate resistance in the host leads to rabbit numbers increasing yet again. We are continuing research to find new strategies that will help maintain benefits of biocontrol in the future.

The Sol Sherry Thrombosis Research Center of Temple University School of Medicine is dedicated to advancing our understanding of the etiology, pathogenesis, diagnosis, and treatment of arterial and venous thrombosis and hemorrhagic diseases. To fulfill this goal, our investigators examine the role of platelets, plasma coagulation factors, protease inhibitors, and neutrophils in thrombogenesis and inflammatory disorders. As normal biochemical and physiologic mechanisms are elucidated, departures from these patterns of response provide knowledge of pathologic processes, providing a necessary platform for the development of diagnostic tests. Each research project in the Center has the potential to initiate appropriate inhibitory drugs or other therapeutic approaches in preventing platelet aggregation, blood coagulation, neutrophil activation, and fibrin formation - all of which contribute to the formation of an obstructive thrombus ...
