The survey is based on a total of 1263 records (738 isolations and 525 molecular DNA detections) of five Borrelia burgdorferi s.l. genomic groups available from 26 European countries: B. burgdorferi sensu stricto, B. afzelii, B. garinii, B. valaisiana (= VS116) and B. lusitaniae (= PoTiB2). It shows the geographic distribution, the source (ixodid ticks 802 records, fleas 2 records, mosquitoes 2 records, wild mammals 66 records, human patients 391 records) and the association of the genomic groups with particular clinical manifestations of Lyme borreliosis in humans (B. afzelii significantly prevails in skin lesions whereas B. garinii is more often associated with neuroborreliosis). The most frequent genomic groups in Europe are B. garinii (501 records) and B. afzelii (469 records). They occur across the continent and islands, whereas the third frequent genomic group, B. burgdorferi s.s. (201 records), has only rarely been isolated in eastern Europe. The remaining genomic groups, i.e. B. valaisiana (85 records) and B. lusitaniae (7 records) have only been isolated from, or detected in, Ixodes ricinus ticks in a few European countries.

The proposed method consists in examining individual host-seeking vector ticks of the Ixodes ricinus complex by microscopy for borreliae and evaluating the proportion of ticks with more than 100 borreliae. The investigations were carried out in a deciduous oak forest habitat in South Moravia, Czech Republic, over four years (1991-1994). In May (i.e., at the peak of seasonal activity of I. ricinus), about 150 nymphal and 200 adult ticks were examined each year. It was found that annual incidence of human Lyme borreliosis in the region correlated better with the proportion of heavily infected ticks than with the overall infection rate of the ticks.
