Transmission of Borrelia afzelii from Apodemus mice and Clethrionomys voles to Ixodes ricinus ticks: differential transmission pattern and overwintering maintenance.

摘要: This study deals with the ecology of Lyme borreliosis in Europe. The relationships between Borrelia burgdorferi sensu lato spirochetes, Clethrionomys and Apodemus rodent reservoirs Ixodes ricinus tick vector were investigated during 16 consecutive months an enzootic area Switzerland. Cultivation ear skin biopsies was used to isolate spirochetes from C. glareolus, A. sylvaticus, flavicollis Glis glis. infection more frequently observed than Apodemus. Tick xenodiagnosis determine infectivity rodents. rate ticks fed on higher that Apodemus, but yielded infected because a better moulting success. Xenodiagnostic placed into BSK medium obtain isolates. Isolates rodents rodent-feeding all identified as B. afzelii. follow-up status repeatedly recaptured clearly demonstrated these hosts remained infective for winter till following spring. Comparing glareolus each species showed different host infection, contributed differently success feeding ticks. These factors influence differentially pattern transmission afzelii voles mice I.
