A disfiguring and debilitating neoplastic condition known as devil facial tumor disease (DFTD) has been discovered in wild Tasmanian Devils (Sarcophilus harrisii) across 51% of its natural range, with population declines of up to 80% in some areas (C. Hawkins, personal communication). Between 2001 and 2004, 91 cases were examined. The tumors presented as(More)
An emerging infectious facial cancer threatens Tasmanian devils with extinction. The disease is likely to occur across the range of the devil within 5 years. This urgent time frame requires management options that can be implemented immediately: the establishment of insurance populations, in captivity, wild-living on islands, and aiming for eradication in(More)
Human infections with Nipah virus in Malaysia and Bangladesh are associated with markedly different patterns of transmission and pathogenicity. To compare the 2 strains, we conducted an in vivo study in which 2 groups of ferrets were oronasally exposed to either the Malaysia or Bangladesh strain of Nipah virus. Viral shedding and tissue tropism were(More)
The Tasmanian devil (TD) (Sarcophilus harrisii) is under threat from devil facial tumour disease (DFTD), a cancer that is transmitted between devils by direct cell implantation. As no devil is known to have rejected the tumour allograft, an understanding of the immune status of this species is essential to help explain the unique infectious nature of this(More)
This case study discusses in detail for the first time the diagnosis and management of a case of leishmaniosis in a dog imported to Australia. The dog presented with epistaxis and a non-regenerative anaemia five years after being imported from Europe. Protozoa were identified within macrophages in bone marrow and splenic cytology. A Leishmania indirect(More)
BACKGROUND Since its initial detection in Norway in 1998, atypical scrapie ('atypical/Nor98 scrapie') has been reported in sheep in the majority of European countries (including in regions free of classical scrapie) and in the Falkland Islands, the USA, Canada, New Zealand and Australia. CASE SERIES The diagnosis in Australia of atypical scrapie in four(More)
Newcastle disease is an important disease of poultry caused by virulent strains of Newcastle disease virus (NDV). During the 1998 to 2002 outbreaks of Newcastle disease in Australia, it was observed that the mild clinical signs seen in some chickens infected with NDV did not correlate with the viruses' virulent fusion protein cleavage site motifs or(More)
BACKGROUND Avian influenza viruses (AIVs) are found worldwide in numerous bird species, causing significant disease in gallinaceous poultry and occasionally other species. Surveillance of wild bird reservoirs provides an opportunity to add to the understanding of the epidemiology of AIVs. METHODS This study examined key findings from the National Avian(More)
