Transmission of the Lyme borreliosis spirochete at the mammal reservoir: tick vector interface in Sweden

During 1988 to 1995 we examined the density of questing Ixodes ricinus nymphs infected with Borrelia burgdorferi s.l. at 12 areas in southern and southcentral Sweden. There were great differences in the density of questing Borrelia-infected I. ricinus nymphs between these areas, i.e., from <10 to >500 infected nymphs per hectare. The density of I. ricinus nymphs had a greater impact on this variation than the prevalence of Borrelia-infection in the nymphs, suggesting that reservoir incompetent cervids, which are important hosts for adult female I. ricinus, indirectly increase the risk of encountering Borrerlia-infected nymphal ticks despite the ability of cervids to divert larval ticks from reservoir competent mammals. There was a strong correlation between the mean number of Borrelia-infected nymphs per hectare and the mean number of nymphs per hectare, suggesting that it may be possible to assess the risk of encountering Borrelia-infected ticks in different areas without examining the prevalence of spirochetal infection.
