studies on the ecology of lyme disease in a deer forest in county galway, ireland.the abundance of the tick ixodes ricinus (l.) and the infection rate of ticks with borrelia burgdorferi (johnson et al.) were compared on either side of a deer fence in a forest park in county galway, ireland, in an attempt to elucidate the role of fallow deer, dama dama, and woodmice, apodemus sylvaticus, in determining the population density of i. ricinus and the transmission of b. burgdorferi. the results showed that tick numbers were much higher on the deer side of the fence, although the de ...19921460628
potential role of native and exotic deer and their associated ticks (acari: ixodidae) in the ecology of lyme disease in california, usa.the relationship of native columbian black-tailed deer, two species of exotic deer (axis and fallow), and their ticks to the lyme disease spirochete, borrelia burgdorferi, was studied in coastal and inland areas of northern california, usa. spirochetemias were detected in 27% of black-tailed deer, 50% of axis deer, and 56% of fallow deer collected in late fall and winter. antibody prevalence was 38% in black-tailed deer, 24% in fallow deer, and 6% in axis deer. one to 3 tick species were collect ...19863554845
[epidemiologic study of lyme disease in asturias].the aim of this study was to confirm the sierra del sueve (asturias) as an endemic area for lyme's disease and determine the seroprevalence of this disease in inhabitants of this and other zones of asturias.19938260513
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
relationship between ixodes ricinus density and prevalence of infection with borrelia-like spirochetes and density of infected ticks.during 1994-1995 we examined the density of questing ixodes ricinus (l.) nymphs and their prevalence of infection with borrelia-like spirochetes at 43 localities in south-central sweden with median nymphal densities ranging from 0.1 to > 50/100 m2. the general pattern was that the infection prevalence in nymphs increased with nymphal density at < 10 nymphs per 100 m2, peaked (20-30%) at 10-20 nymphs per 100 m2, and decreased at higher nymphal densities. a low infection prevalence (7-10%) in nymp ...19968840687
low risk of lyme borreliosis in a protected area on the tyrrhenian coast, in central italy.a comprehensive lyme borreliosis risk assessment process was applied in s. rossore estate, on the tyrrhenian coast, near pisa, italy. host-seeking ixodes ricinus nymphs peaked in may in oak-dominated deciduous wood (median, q1-q3, number of nymphs/50 m dragging = 4.5, 2.5-8), whereas host-seeking larvae peaked in august in the same habitat type (6.0, 4-17/50 m dragging). prevalence of i. ricinus infestation was 88.9% in wild rodents (n = 11), 64.3% in fallow deer (n = 28) and 0.0% in wild boars ...199910414379
protein a/g dependent elisa a promising diagnostic tool in lyme disease seroprevalence in game animals and hunting dogs.one of the major problems in serodiagnosis in wild animals is unavailability of specific antiglobulin conjugate. our study focuses on validation of protein a/g dependent elisa in game animals like deer and mouflons as well as in hunting dogs. binding ability of protein a/g-conjugate to antibodies was the highest in dogs followed by fallow deer and mouflons. three different whole cell borrelia antigens were used to evaluate antigen dependent variation. in new protein a/g-elisa the highest sensiti ...200415001314
immunoglobulin g antibodies to borrelia burgdorferi in game animals and small mammals in eastern slovakia.in a survey of game animals and small mammals, the sera of 185 animals were examined for the presence of immunoglobulin g antibodies to the spirochete borrelia burgdorferi sensu lato, which causes lyme borreliosis. these animals comprised 59 fallow deer (dama dama), 56 mouflons (ovis musimon) and 70 small mammals of six different species. the sera of the fallow deer and the mouflons were examined by indirect haemagglutination assay. the sera of the small mammals were examined by modified enzyme- ...200315005560
molecular detection of tick-borne bacteria and protozoa in cervids and wild boars from portugal.wildlife can act as reservoir of different tick-borne pathogens, such as bacteria, parasites and viruses. the aim of the present study was to assess the presence of tick-borne bacteria and protozoa with veterinary and zoonotic importance in cervids and wild boars from the centre and south of portugal.201627160767
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
use of peroxidase-labelled antigen for the detection of antibodies to borrelia burgdorferi in human and animal sera.we have developed a modified elisa for the detection of anti-borrelia burgdorferi (bb) antibodies based on a peroxidase enzyme labelled antigen (elat). microtiter plates were coated with antigen of bb. the immunoglobulins of the serum samples were bound to the antigen and specific antibodies were detected by an enzyme labelled antigen. the test principle facilitates the recognition of specific antibodies in different collectives of human and animal sera. we performed epidemiological studies with ...19912028231
