THE FIRST TICK‐BORNE ENCEPHALITIS VIRUS ISOLATES FROM NORWAY

Abstract
Five virus strains with close serological relationship to the tick-borne encephalitis (TBE) complex have been isolated from Ixodes ricinus ticks. The ticks were collected in early June 1976 at three different locations in Sogn & Fjordane County, Norway. One of the virus-yielding pools was composed of ticks collected between the cabins on a tourist camping ground.
