Item ICTV Virus Taxonomy Profile: Arteriviridae 2021(Microbiology Society, 2021-08-06) Brinton MA; Gulyaeva AA; Balasuriya UBR; Dunowska M; Faaberg KS; Goldberg T; Leung FCC; Nauwynck HJ; Snijder EJ; Stadejek T; Gorbalenya AEThe family Arteriviridae comprises enveloped RNA viruses with a linear, positive-sense genome of approximately 12.7 to 15.7 kb. The spherical, pleomorphic virions have a median diameter of 50-74 nm and include eight to eleven viral proteins. Arteriviruses infect non-human mammals in a vector-independent manner. Infections are often persistent and can either be asymptomatic or produce overt disease. Some arteriviruses are important veterinary pathogens while others infect particular species of wild rodents or African non-human primates. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Arteriviridae, which is available at ictv.global/report/arteriviridae.Item The aetiology of wobbly possum disease: Reproduction of the disease with purified nidovirus.(2016-04) Giles J; Perrott M; Roe W; Dunowska MThe objective of this study was to investigate a role of a recently discovered marsupial nidovirus in the development of a neurological disease, termed wobbly possum disease (WPD), in the Australian brushtail possum (Trichosurus vulpecula). Four possums received 1 mL of a standard inoculum that had been prepared from tissues of WPD-affected possums, 4 possums received 1.8 mL (1 × 10(6) TCID50) of a cell lysate from inoculated cultures, and 4 possums received 1 mL (× 10(7) TCID50) of a purified WPD isolate. All but one possum that received infectious inocula developed neurological disease and histopathological lesions characteristic for WPD. High levels of viral RNA were detected in livers from all possums that received infectious inocula, but not from control possums. Altogether, our data provide strong experimental evidence for the causative involvement of WPD virus in development of a neurological disease in infected animals.
