distribution and prevalence of borrelia burgdorferi sensu lato in ixodes ricinus ticks of canton ticino (switzerland).free-living ixodes ricinus ticks were collected from 12 different sites of canton ticino, south of the alps (switzerland). each tick was examined for the presence of borrelia burgdorferi sensu lato (sl), the etiologic agent of lyme borreliosis using direct fluorescent antibody assay, and isolation of the bacteria. borreliae were characterized by pcr followed by rflp. the abundance and infection rates of i. ricinus ticks varied greatly between the areas. two localities were found free of borrelia ...200314561052
tick zoonoses in the southern part of switzerland (canton ticino): occurrence of borrelia burgdorferi sensu lato and rickettsia sp.the diversity and the distribution of tick species and their infection rates by the pathogenic micro-organism borrelia burgdorferi sensu lato, the etiologic agent of lyme borreliosis, and rickettsia sp., were studied in canton ticino (the southern part of switzerland). ticks specimens collected from animals and humans were classified and analysed for the presence of both pathogens. in particular, pcr analysis was performed for the detection of borrelia spirochetes in ixodes ricinus and ixodes he ...19979085007
borrelia burgdorferi in ticks of the canton tessin (switzerland).in the northern alps it is hard to find an ixodes ricinus population which does not harbour borrelia burgdorferi. the infection rates range from 5 to 34% for adults and nymphs to 3.1% for larvae. this study shows that the infection rates on the southern side of the alps are similar, at 25% for adults, 36.2% for nymphs and 3.2% for larvae. with respect to tick species other than i. ricinus, we did not succeed in finding any spirochetes in dermacentor marginatus, haemaphysalis punctata, ixodes hex ...19902132440
