incompetence of roe deer as reservoirs of the lyme borreliosis spirochete.to determine whether the roe deer, capreolus capreolus l. may serve as a reservoir host for the lyme disease spirochete, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, evidence of spirochetal infection was sought in nymphal ixodes ricinus (l.) that had engorged as larvae on roe deer. sixteen roe deer were shot in lyme disease enzootic areas of south-central sweden during august-november 1990 and august 1991. an average of 276 (range, 84-658) larvae of i. ricinus was collected ...19921404260
transmission of borrelia burgdorferi s.l. from mammal reservoirs to the primary vector of lyme borreliosis, ixodes ricinus (acari: ixodidae), in sweden.factors regulating prevalence of borrelia burgdorferi s.l. johnson, schmid, hyde, steigerwalt & brenner in ixodes ricinus (l.) were examined during 1991-1992 at bogesund, near stockholm in south-central sweden. nine species of small and medium-sized mammals (sorex araneus l., s. minutus l., neomys fodiens pennant, clethrionomys glareolus [schreber], microtus agrestis [l.], apodemus sylvaticus [l.], a. flavicollis [melchior], lepus europaeus pallas, l. timidus l.) were found to infect feeding tic ...19947815401
prevalence of antibodies to borrelia burgdorferi in danish deer.to estimate the prevalence of antibodies to borrelia burgdorferi in the most common species of danish deer, blood samples were collected from roe deer (capreolus capreolus), fallow deer (dama dama), and red deer (cervus elaphus). a total of 156 blood samples were collected primarily from hunts in three areas of denmark from november 1990 to december 1991. presence of deer igg antibodies to the borrelia burgdorferi strain dk ecm 1 were shown by an indirect immunofluorescence assay at serum titre ...19948011306
diversionary role of hoofed game in the transmission of lyme disease spirochetes.to determine whether the presence of ungulates may inhibit transmission of the agent of lyme disease (borrelia burgdorferi) while promoting the abundance of its european vector tick (ixodes ricinus), we compared the feeding density of subadult ticks on roe deer (capreolus capreolus), red deer (cervus elaphus), fallow deer (dama dama), and wild sheep (ovis ammon) near berlin and in brandenburg state, germany. the prevalence of spirochetal infection in these ticks was compared with that in ticks s ...19938517488
classification tree methods for analysis of mesoscale distribution of ixodes ricinus (acari:ixodidae) in trentino, italian alps.cases of lyme disease and tick-borne encephalitis were recognized recently in the province of trento, italian alps. assessment of areas of potential risk for these tick-borne diseases is carried out by a model based on classification and regression trees (cart), using both discrete and continuous variables. data on ixodes ricinus (l.) occurrence resulted from extensive sampling carried out by standard methods in 99 sites over an area of approximately 2,700 km2 in the province of trento. a series ...19968961635
detection of four species of borrelia burgdorferi sensu lato in ixodes ricinus ticks collected from roe deer (capreolus capreolus) in the netherlands.roe deer (capreolus capreolus) were investigated for their value as sentinel animals for lyme borreliosis in the netherlands. serum was obtained from 114 roe deer, and 513 ixodes ricinus, predominantly females (72%), were obtained from 47 animals (41%). the polymerase chain reaction was used to detect dna of borrelia burgdorferi sensu lato in a total of 190 ticks, comprising 106 engorged ticks and 84 non-engorged ticks. borrelia dna was detected in 24 engorged ticks (23%) and 26 non-engorged tic ...19968972683
ixodes ricinus (acari: ixodidae) infestation on roe deer (capreolus capreolus) in trentino, italian alps.the most important tick-deer system potentially supporting the epidemiology of lyme disease in the italian alps is that regarding ixodes ricinus (l.) and roe deer (capreolus capreolus l.). in this study, the pattern of tick infestation on 562 male roe deer harvested in september 1994 in 56 game districts of trentino, northern italy, was assessed. the prevalence and density of infestation by i. ricinus were analyzed by a model based on classification and regression trees (cart), using both discre ...19979419849
a paretic condition in an anaplasma phagocytophilum infected roe deer calf.this paper describes a case of anaplasma phagocytophilum infection in a roe deer (capreolus capreolus) calf in norway. the calf was found deserted, paretic, and heavily infested with ixodes ricinus ticks. it was euthanized and investigated postmortem. anaplasma phagocytophilum was detected in several tissues by polymerase chain reaction (pcr) and 16s rrna sequence analyses. analyses for borrelia burgdorferi sensu lato and tick-borne encephalitis (tbe) virus infections were negative. this is the ...200616699161
prevalence of borrelia burgdorferi in ixodes ricinus ticks collected from moose (alces alces) and roe deer (capreolus capreolus) in southern norway.as part of a larger survey, ears from 18 roe deer (capreolus capreolus) and 52 moose (alces alces) shot in the 2 southernmost counties in norway were collected and examined for ixodes ricinus ticks. seventy-two adult ticks, 595 nymphs, and 267 larvae from the roe deer, and 182 adult ticks, 433 nymphs, and 70 larvae from the moose were investigated for infection with borrelia burgdorferi sensu lato (s.l.). the results showed the presence of b. burgdorferi s.l. dna in 2.9% of the nymphs collected ...201121771543
seroprevalence of borrelia burgdorferi sensu lato in roe deer (capreolus capreolus) from northwestern spain.in the present study, the seroprevalence of borrelia burgdorferi sensu lato in roe deer in relation to different parameters in northwestern spain was investigated. a total of 154 roe deer hunted between april 2007 and october 2008 from different localities of galicia (northwest spain) were examined. from each animal, a blood sample and all attached ticks found were collected. all the specimens for tick stages (larva, nymph, and adult) were speciated based on reference keys. antibodies against b. ...201324063094
[ixodes ricinus, transmitted diseases and reservoirs].the tick ixodes ricinus has been recorded in most italian regions especially in thermo-mesophilous woods and shrubby habitats where the relative humidity allow the tick to complete its 3 year developmental cycle, as predicted for the european climatic ranges. this tick acts both as vector and reservoir for a series of wildlife zoonotic pathogens, especially the agents of lyme diseases, tick borne encephalitis and human granulocytic ehrlichiosis, which are emerging in most of europe. to assess th ...200415305699
