[Serologic diagnosis of infections caused by Borrelia burgdorferi].

This investigation was aimed at selection of optimal serological test for diagnosis of borreliosis occurring at our territory. In our investigations, and indirect immunofluorescence test (IF) was used in which antigen consisted of an American strain of Borrelia burgdorferi B31 and immunoenzymatic test (IE) with an antigen prepared from an European strain. Hundred sixty eight sera were tested, including 138 sera received from patients with suspection of borreliosis or directed for testing because of suspected tick bite. Thirty sera from healthy blood donors served as a control. In 30 out of 138 patients with suspected borreliosis presence of specific antibodies in IF or IE test was detected. In control group positive results were obtained in 4 persons. From our study comparing two tests occurs that more suitable for serodiagnosis of borreliosis on our territory is determination employing as an antigen the European strain of Borrelia burgdorferi.
