| infection of ixodes ricinus (acari:ixodidae) by borrelia burgdorferi in ile de france. | free-living nymphs and adults from rambouillet and fontainebleau, 2 major forests of ile de france, were collected to determine the infection rates of ixodes ricinus l. by borrelia burgdorferi (johnson, schmid, hyde, steigerwalt & brenner). field-collected i. ricinus nymphs and adults were screened for the presence of b. burgdorferi using direct fluorescent antibody assay. the infection rates of nymph, male and female were 12.4% (314), 2.8% (35), and 2.9% (34). no difference in infection rates o ... | 1996 | 8699470 |
| density of deer in relation to the prevalence of borrelia burgdorferi s.l. in ixodes ricinus nymphs in rambouillet forest, france. | the rambouillet forest, a lyme disease-endemic area near paris, france, was surveyed from september 1994 to october 1995 to determine the risk periods and zones for humans. firstly, during the period of ixodes ricinus activity, abundance of nymphs is greater in spring than in autumn. secondly, we observed significant variation in nymphal abundance between zones according to the density of cervids. the polymerase chain reaction (pcr) was used to detect dna of borrelia burgdorferi sensu lato in 46 ... | 1999 | 10356769 |
| introduced siberian chipmunks are more heavily infested by ixodid ticks than are native bank voles in a suburban forest in france. | by serving as hosts for native vectors, introduced species can surpass native hosts in their role as major reservoirs of local pathogens. during a 4-year longitudinal study, we investigated factors that affected infestation by ixodid ticks on both introduced siberian chipmunks tamias sibiricus barberi and native bank voles myodes glareolus in a suburban forest (forêt de sénart, ile-de-france). ticks were counted on adult bank voles and on adult and young chipmunks using regular monthly trapping ... | 2010 | 20406644 |
