Seven virus isolations from Ixodes Uriae collected during July 1971 from a puffin ( Fratercula arctica ) colony on Great Island, Newfoundland, Canada were identified by complement-fixation tests as belonging to the Kemerovo-Tribeč complex of the Kemerovo serogroup of orbiviruses. Neutralization tests indicated that 2 new members of the complex were represented in the 7 isolates. These agents are designated Great Island virus (prototype strain CanAr 41) and Bauline virus (prototype strain CanAr 14). Both agents were inactivated by exposure to pH 3.0. CanAr 41 was resistant to sodium deoxycholate, ether, and chloroform, while CanAr 14 was susceptible to these solvents. No hemagglutinin was demonstrated for either virus using goose erythrocytes. Great Island virus kills suckling mice by intracerebral (ic) and intraperitoneal (ip) inoculation and weanling mice by ic but not ip routes; Bauline virus is fatal to suckling, but not weanling, mice inoculated ic and ip. Both viruses kill day-old chicks by ic and subcutaneous routes.
