title: Unknown species of rickettsiae isolated from Ixodes ricinus tick in Wałcz.
abstract: Ticks Ixodes ricinus have been harvested in park down-town Wałcz in June 1994. Presence of Borrelia burgdorferi and rickettsiae has been tested with PCR. B. burgdorferi and Coxiella burnetii have not been detected in any tick whereas characteristic for other rickettsiae DNA fragment of gene encoding citrate-synthase has been found. Bacterial strain has been cultured from the tick. Biochemical properties of isolated strain has strongly suggested that these bacteria belong to genus Bartonella (Rochalimaea). Further identification of bacterial DNA with RFLP-PCR (restriction fragment length polymorphism-PCR) has shown characteristics of Bartonella bacilliformis species not recognised in Poland until recently.
