distribution of borrelia burgdorferi s.l. spirochaete dna in british ticks (argasidae and ixodidae) since the 19th century, assessed by pcr.the distribution of borrelia burgdorferi sensu lato, the lyme borreliosis agent, was surveyed in british ticks in the collection of the natural history museum, london. alcohol-preserved specimens of eight species of ticks known to attack humans were studied: ixodes ricinus, i. hexagonus, i. uriae, i. trianguliceps, dermacentor reticulatus, haemaphysalis punctata, rhipicephalus sanguineus and argas vespertilionis. the sample comprised all life stages and originated from a wide range of host speci ...19989513944
tick surveillance in great britain.the ability for public/veterinary health agencies to assess the risks posed by tick-borne pathogens is reliant on an understanding of the main tick vector species. crucially, the status, distribution, and changing trends in tick distribution and abundance are implicit requirements of any risk assessment; however, this is contingent on the quality of tick distribution data. since 2005 the health protection agency has promoted an enhanced tick surveillance program. through engagement with a variet ...201120849277
first detection of spotted fever group rickettsiae in ixodes ricinus and dermacentor reticulatus ticks in the uk.a preliminary study was conducted to determine the presence of spotted fever rickettsiae in two species of british tick (ixodes ricinus and dermacentor reticulatus). the 16s rrna gene of rickettsia spp. was detected in 39/401 (9·7%) of ticks tested, including 22/338 (6·5%) i. ricinus and 17/63 (27%) d. reticulatus. some positive i. ricinus samples showed 100% homology with rickettsia helvetica (10/22), and most positive d. reticulatus showed 100% homology with r. raoultii (13/17). five other ric ...201021087541
prevalence, distribution and risk associated with tick infestation of dogs in great britain.current concerns over the potential impacts of climate change and the increased movement between countries of people and companion animals on the distribution of ectoparasites, highlight the need for accurate understanding of existing prevalence patterns. without these future changes will not be detected. here, the distribution and prevalence of tick infestations of domestic dogs in great britain were examined. a total of 173 veterinary practices were recruited to monitor tick attachment to dogs ...201121418263
