摘要：

Unfed nymphal Ixodes ricinus, Haemaphysalis concinna, and adult Dermacentor reticulatus were collected in two locations of Saxony in July and September 1991 by flagging. In July, the abundance of nymphal I.ricinus was about 2-3 times higher than that of nymphal H.concinna, a time of the year when nymphs of both species are reported to have a seasonal peak of activity. No D.reticulatus were flagged concurrently. In September, host-seeking activity of nymphal I.ricinus was again quite high as was that of adult D.reticulatus but only low numbers of nymphal H.concinna were collected. The flagged ticks were individually examined for Borrelia by an indirect immunofluorescence assay (I.ricinus: n = 414, H.concinna: n = 96; D.reticulatus: n = 116). The prevalence of Borrelia (probably B.burgdorferi) in I.ricinus varied from 12.1% to 21.0%. No borreliae were found in H.concinna. Of the examined D. reticulatus from one site (n = 97) 11.3% contained either B.burgdorferi or a related Borrelia. This may be the first finding of Borrelia in an Eurasian Dermacentor species.
