    The altitudinal shift in the limit of Ixodes ricinus occurrence above the previously established altitude of 750m above sea level has been monitored over the long-term (2002–2008) in the Krkonose Mts. along two vertical transects in their eastern and central parts (600–1020 and 600–1270 m). Ticks were collected by flagging three times annually, and examined individually by PCR or RT-PCR for the presence of Borrelia burgdorferi s. l. or tick-borne encephalitis virus (TBEV). A total of 5999 I. ricinus ticks were tested. TBEV RNA was detected in 26 ticks at up to 1140 m. B. burgdorferi sensu stricto was found at up to 1040–1065m, B. garinii and B. afzelii up to 1080–1140m, and B. valaisiana up to 1270 m. The total infection rates of nymphs and larvae were 7.3% and 2%, respectively. Upon analysis of the local climate we consider climate warming to be responsible for the spreading of ticks and tick-transmitted pathogens to higher altitudes.
