  1. aTick developmental stage: AM, adult male; AF, adult female; N, nymph
  2. bOne nymph in this group was morphologically and molecularly identified as Ixodes ricinus. This nymph was negative for Borrelia
  3. cOne adult female from Västra Knivskär was positive for Rickettsia helvetica and one nymph from Östra Knivskär was positive for Rickettsia sp. Both Rickettsia-positive ticks were negative for Borrelia
