Prevalence of Borrelia burgdorferi sensu stricto, Borrelia afzelii, Borrelia garinii, and Borrelia valaisiana in Ixodes ricinus ticks from the northwest of Norway

Abstract

The overall infection rate is somewhat lower than that reported in the most recent study of the infection rate in southern Norway in 2010, and this study indicates that the infection rate varies from one year to another.
