The isolation of arboviruses including a new flavivirus and a new Bunyavirus from Ixodes (Ceratixodes) uriae (Ixodoidea: Ixodidae) collected at Macquarie Island, Australia, 1975-1979.

Pools of ticks, Ixodes (Ceratixodes) uriae collected between 1975 and 1979 at Macquarie Island, yielded 33 strains of at least 4 different viruses: Nugget virus (Kemerovo group), 1 strain; Taggert virus (Sakhalin group) 9 strains; a previously undescribed flavivirus, related to Central European Tickborne encephalitis virus, for which the name "Gadgets Gully" is proposed, 9 strains; a virus serologically related to the Uukuniemi serogroup, family Bunyaviridae, for which the name "Precarious Point" is proposed, 10 strains. Three isolates were mixtures of Nugget and Gadgets Gully viruses; the remaining virus strain remains unidentified.
