Ongoing Surveillance

ABSTRACTRabbit hemorrhagic disease virus 2(RHDV2;LagovirusGI.2) is a pathogenic calicivirus that affects European rabbits (Oryctolagus cuniculus) and various hare (Lepus) species. GI.2 was first detected in France in 2010 and subsequently caused epidemics in wild and domestic lagomorph populations throughout Europe. In May 2015, GI.2 was detected in Australia. Within 18 months of its initial detection, GI.2 had spread to all Australian states and territories and rapidly became the dominant circulating strain, replacingRabbit hemorrhagic disease virus(RHDV/GI.1) in mainland Australia. Reconstruction of the evolutionary history of 127 Australian GI.2 isolates revealed that the virus arrived in Australia at least several months before its initial description and likely circulated unnoticed in wild rabbit populations in the east of the continent prior to its detection. GI.2 sequences isolated from five hares clustered with sequences from sympatric rabbit populations sampled contemporaneously, indicating multiple spillover events into hares rather than an adaptation of the Australian GI.2 to a new host. Since the presence of GI.2 in Australia may have wide-ranging consequences for rabbit biocontrol, particularly with the release of the novel biocontrol agent GI.1a/RHDVa-K5 in March 2017, ongoing surveillance is critical to understanding the interactions of the various lagoviruses in Australia and their impact on host populations.IMPORTANCEThis study describes the spread and distribution ofRabbit hemorrhagic disease virus 2(GI.2) in Australia since its first detection in May 2015. Within the first 18 months following its detection, RHDV2 spread from east to west across the continent and became the dominant strain in all mainland states of Australia. This has important implications for pest animal management and for owners of pet and farmed rabbits, as there currently is no effective vaccine available in Australia for GI.2. The closely related RHDV (GI.1) is used to control overabundant wild rabbits, a serious environmental and agricultural pest in this country, and it is currently unclear how the widespread circulation of GI.2 will impact ongoing targeted wild rabbit management operations.

Detection And Diagnosis

Since the early 1980s, the European rabbit (Oryctolagus cuniculus) has been threatened by the rabbit hemorrhagic disease (RHD). The disease is caused by a lagovirus of the family Caliciviridae, the rabbit hemorrhagic disease virus (RHDV). The need for detection, identification and further characterization of RHDV led to the development of several diagnostic tests. Owing to the lack of an appropriate cell culture system for in vitro propagation of the virus, much of the methods involved in these tests contributed to our current knowledge on RHD and RHDV and to the development of vaccines to contain the disease. Here, we provide a comprehensive review of the RHDV diagnostic tests used since the first RHD outbreak and that include molecular, histological and serological techniques, ranging from simpler tests initially used, such as the hemagglutination test, to the more recent and sophisticated high-throughput sequencing, along with an overview of their potential and their limitations.

Capsid Protein Vp60

Rabbit hemorrhagic disease virus (RHDV) has two structural proteins: the major capsid protein VP60 and the minor capsid protein VP2. VP2 is speculated to play an important role in the virus life cycle. To investigate the effect of VP2 on VP60 expression, three types of experiment (baculovirus–insect cell system, mammalian–luciferase assay system and in vitro coupled transcription/translation system) were used to express VP60 alone or co-expressed with VP2. Both forms of VP60 were able to form virus-like particles in insect cells. Western blot analysis and dual-luciferase assays demonstrated that the presence of VP2 results in downregulation of the expression of VP60 in vivo. Real-time RT-PCR of mRNA levels showed that downregulation of VP60 occurs at the transcriptional level. The ability of the viral minor structural protein VP2 to regulate capsid protein levels may contribute to effective virus infection.
