“…Native mammals are considered to be important hosts for RRV and there is no extensive involvement of birds in natural transmission (Doherty et al, 1971). The relatively low mobility of the natural hosts of RRV may result in geographical isolation of local virus populations.…”

Summary. The genotypic relatedness of 15 Kunjin (KUN) virus isolates from widely separated geographic regions in Australia was examined at the molecular level. Haelll and TaqI restriction digest profiles of cDNA transcribed from virion RNA revealed a close genetic similarity between all isolates. We estimate that the nucleotide sequence divergence between any pair of KUN . isolates is probably less than 1%. We conclude that a single KUN genetic type has existed in enzootic and epizootic areas of virus activity over an extended time span. The epidemiological implications of these results are discussed.

Between October 1974 and May 1976, 57596 mosquitoes, 169957 Culicoides, 5923 Lasiohelea and 1043 phlebotomines were collected for virus isolation at Beatrice Hill (lat. 12�39'S.,long. 131�20'E.) in the Northern Territory of Australia. A total of 94 viruses belonging to 22 different serological groupings was isolated. The following species of insect yielded viruses which were identified and those viruses marked with an asterisk represent a new record of insect host:

“…1 Macropods are believed to be the major hosts of RR, with seropositivity rates of Ͼ 80% recorded in north Queensland. 2 Experimental inoculations of animals with RR indicate that marsupials are the most competent of the potential vertebrate hosts, ahead of placental mammals. 3 There is seroepidemiological evidence suggesting that mammals, particularly marsupials, also act as vertebrate hosts of BF.…”

“…In fact, dogs have commonly been found with RR antibody. 2,7 However, nothing is known about the role that these species have in the persistence of the virus in urban environments. Given that both BF and RR antibodies have been found in the same host species and have been isolated from the same mosquito species, it is possible that the transmission cycles of both viruses involve these urban animals as reservoir hosts.…”

Abstract. Brushtail possums, Trichosurus vulpecula Kerr, were experimentally infected with Ross River (RR) or Barmah Forest (BF) virus by Aedes vigilax (Skuse) mosquitoes. Eight of 10 animals exposed to RR virus developed neutralizing antibody, and 3 possums developed high viremia for Ͻ 48 hr after infection, sufficient to infect recipient mosquitoes. Two of 10 animals exposed to BF virus developed neutralizing antibody. Both infected possums maintained detectable neutralizing antibody to BF for at least 45 days after infection (log neutralization index Ͼ 2.0 at 45 days). Eight possums did not develop neutralizing antibody to BF despite exposure to infected mosquitoes. These results suggest that T. vulpecula may potentially act as a reservoir species for RR in urban areas. However, T. vulpecula infected with BF do not develop viremia sufficient to infect mosquitoes and are unlikely to be important hosts for BF.
