Arboviruses of Coastal South‐eastern Australia

Abstract

Summary During investigations of epidemic polyarthritis at Nelson Bay, New South Wales, 12 strains of Ross River virus, the causative agent, were recovered from pools of mosquitoes. In addition, the mosquito pools yielded 9 strains of the flavivirus Edge Hill, 4 strains of a bunyavirus, Gan Gan, 1 strain of an orbivirus Tilligerry, and 1 strain of an ungrouped probable arbovirus, Yacaaba. The latter 3 viruses were found to be antigenically distinct from previously recorded arboviruses. A case of epidemic polyarthritis probably contracted at Bawley Point, approximately 400 kilometres south of Nelson Bay on the south coast of New South Wales, is recorded. Mosquitoes collected in the nearby Termeil State Forest one year later yielded a strain of Ross River virus and 5 strains of a previously undescribed ungrouped togavirus, Termeil. The extent of arboviral activity in temperate coastal areas of south‐eastern Australia was unexpected.

Full Genome Sequencing and Genetic Characterization of Eubenangee Viruses Identify Pata Virus as a Distinct Species within the Genus Orbivirus

“…It does not cross-react strongly in serological assays with other EUBV isolates and it is not closely related to EUBV by hybridrization [19], [41], [42], leading to suggestions that the current classification of PATAV should be re-examined [19], [42], [43]. PATAV does show low level cross-reactivity in complement fixation (CF) tests with BTV and EHDV serogroups [19], [43] and it has been suggested that it could be reclassified as an EHDV [19], [43].…”

Human Arbovirus Infections Along the South Coast of New South Wales

“…Ross River (RR) virus activity along the south coast of New South Wales has been previously reported (Cloonan et al, 1982a;Cloonan et al, 1982b) and the virus has been isolated from mosquitoes collected in south coast forests both in 1972 (Marshall, Woodroofe and Gard, 1980) and in 1982 (Cloonan et a!., 1982b). Other arboviruses recovered from mosquitoes collected in the same area include Termeil (TER) virus , Trubanaman (TRU) virus (Vale et al, 1985), Barmah Forest (BF) virus which has been isolated from mosquitoes collected in the Batemans Bay area both in 1984 (Vale et al, 1985) and in 1985 from a pool of Aedes vigilax (Vale, McPhie and Cloonan, unpublished data), and Gan Gan (GG) virus which has been isolated from a pool of Culex spp.…”

GENETIC ANALYSIS OF KUNJIN VIRUS ISOLATES USING HAEIII AND TAQI RESTRICTION DIGESTS OF SINGLE‐STRANDED cDNA TO VIRION RNA

“…Subsequently, KUN has been obtained repeatedly from mosquitoes collected in the Murray Valley region of Victoria and N.S.W. (Marshall and Woodroofe, 1975), at Charleville in Queensland (Doherty et al, 1976) and in the Ord Valley of Western Australia (Liehne et al, 1981). KUN has also been isolated in Sarawak and Thailand.…”
