T Grillo 12/08/2009 12/08/2009 McPhee, S. R., et al. (2009). Antibody status and survival of Australian wild rabbits challenged with rabbit haemorrhagic disease virus. Wildlife Research 36(5): 447-456. Abstract:”In Australia, the epidemiology of rabbit haemorrhagic disease virus (RHDV) is complicated by non-pathogenic forms of calicivirus (bCV) co-circulating with RHDV and providing variable protection from RHDV. Currently no bCV virus-specific antibody tests exist; however, a series of four ELISAs used to detect antibodies to RHDV provided an indirect means to detect antibodies to bCV, enabling antibody categories of seronegative, maternal RHDV, RHDV or bCV to be determined. Rabbits (188) from four locations were challenged with RHDV and logistic regression models determined that, for rabbits <15 months old, survival was dependent on antibody titres alone and the relationship did not vary with age, capture site, gender, liveweight or reproductive status………………….” Follow link: http://www.publish.csiro.au/?paper=WR081
R Woods 08/05/2009 18/05/2009 Dr Tanja Strive from CSIRO Entomology and the Invasive Animals Cooperative Research Centre has found that some rabbits in cool, high rainfall areas carry a benign virus that gives them immunity to RHD. See http://www.sciencealert.com.au/news/20 090805-19100.html
L Haynes 21/02/2008 Rabbit Hemorrhagic Disease - New Zealand: Canterbury, Population Recovery Over the past 2 years, there has been an increase in the number of rabbits on Canterbury farms (New Zealand) now immune to the natural rabbit haemorrhagic disease, or calicivirus. Environment Canterbury biosecurity team leader Brent Glentworth says over the region, there has been an average increase of 3 rabbits per square kilometre. http://www.promedmail.org/pls/otn/f?p=2400:1001:1113469915303408::NO::F2400_P1001_BACK_PAGE,F2400_P1001_ PUB_MAIL_ID:1000,71410 and http://www.promedmail.org/pls/otn/f?p=2400:1001:1113469915303408::NO::F2400_ P1001_BACK_PAGE,F2400_P1001_PUB_MAIL_ID:1000,71423
R Woods 04/10/2005 Rabbit haemorrhagic disease virus is used for control of pest rabbits in Australia. "The rabbit Calicivirus injection was registered for the first time in Australia in September 1996. Registration allowed for this biological control agent to be manufactured and used via injection to control the European rabbit in Australia. A further product RHD virus suspension has now been registered providing a method of delivering the biological control agent via baits. The virus initiates RHD (RCD, 'Calicivirus") which is fatal to susceptible rabbits. The newly registered product will provide land managers with a new delivery method for the biological control of wild rabbit populations. The Commonwealth Scientific and Industrial Reserach Organisation (CSIRO) is the registrant for both the injection product and the new suspension."
