Introduction
The Ixodes ricinus tick is a common ectoparasite in Europe. It is a well known
vector of many human pathogenic viruses, bacteria and protozoa, causing zoonoses and
circulating in natural foci. Birds, including passerines (order Passeriformes) often host
subadult ticks and represent a reservoirs for human tick-borne pathogens [1]. A number
of studies identi ed Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum and
Tick-borne encephalitis virus (TBE) as tick-borne pathogens associated with migratory
birds [1]. B. garinii was detected in ground welling and sea birds in Eurasia while
B. valaisiana and B. burgdorferi sensu stricto were identi ed in different passerine
birds in Europe (9). The human pathogenic members of the family of Anaplasmataceae
and TBE virus have been detected in ticks from different species of migratory birds
collected in Europe [2, 3, 10]. However, birds have so far not been implicated in the
ecology and epidemiology of Spotted Fever Group (SFG) rickettsia and babesia.
Material and Methods
Birds were caught in ornithological nets (permit no. DLOPiKog.4201/154/00)
