seasonal prevalence of lyme disease spirochetes in a heterothermic mammal, the edible dormouse (glis glis).in europe, dormice serve as competent reservoir hosts for particular genospecies of the tick-borne agent of lyme disease (ld) and seem to support them more efficiently than do mice or voles. the longevity of edible dormice (glis glis) and their attractiveness for ticks may result in a predominance of ld spirochetes in ticks questing in dormouse habitats. to investigate the role of edible dormice in the transmission cycle of ld spirochetes, we sampled skin tissue from the ear pinnae of dormice in ...024705325
bartonella spp. bacteremia and rheumatic symptoms in patients from lyme disease-endemic region.bartonella spp. infection has been reported in association with an expanding spectrum of symptoms and lesions. among 296 patients examined by a rheumatologist, prevalence of antibodies against bartonella henselae, b. koehlerae, or b. vinsonii subsp. berkhoffii (185 [62%]) and bartonella spp. bacteremia (122 [41.1%]) was high. conditions diagnosed before referral included lyme disease (46.6%), arthralgia/arthritis (20.6%), chronic fatigue (19.6%), and fibromyalgia (6.1%). b. henselae bacteremia w ...022516098
spatially-explicit simulation modeling of ecological response to climate change: methodological considerations in predicting shifting population dynamics of infectious disease vectors.poikilothermic disease vectors can respond to altered climates through spatial changes in both population size and phenology. quantitative descriptors to characterize, analyze and visualize these dynamic responses are lacking, particularly across large spatial domains. in order to demonstrate the value of a spatially explicit, dynamic modeling approach, we assessed spatial changes in the population dynamics of ixodes scapularis, the lyme disease vector, using a temperature-forced population mode ...024772388
human infections with borrelia miyamotoi, japan.we confirmed infection of 2 patients with borrelia miyamotoi in japan by retrospective surveillance of lyme disease patients and detection of b. miyamotoi dna in serum samples. one patient also showed seroconversion for antibody against recombinant glycerophosphodiester phosphodiesterase of b. miyamotoi. indigenous relapsing fever should be considered a health concern in japan.025061761
geographical and environmental factors driving the increase in the lyme disease vector ixodes scapularis.the population densities of many organisms have changed dramatically in recent history. increases in the population density of medically relevant organisms are of particular importance to public health as they are often correlated with the emergence of infectious diseases in human populations. our aim is to delineate increases in density of a common disease vector in north america, the blacklegged tick, and to identify the environmental factors correlated with these population dynamics. empirica ...024371541
cases of lyme disease in the united states: locations correlated with distribution of ixodes dammini.lyme disease, defined by erythema chronicum migrans and sometimes followed by neurologic, cardiac, or joint involvement, is known to have affected 512 patients in the united states. the disease seems to occur in three distinct foci: along the northeastern coast, in wisconsin, and in california and oregon, a distribution that correlates closely with that of ixodes dammini in the first two areas and with ixodes pacificus in the last. the implicated tick, saved by six patients in the northeast, was ...1979496106

natural distribution of the ixodes dammini spirochete.spirochetes believed to be the cause of lyme disease were isolated from white-footed mice and white-tailed deer, the preferred natural hosts of ixodes dammini, the tick vector. evidence suggests that deer act as a reservoir of the disease and provide an overwintering mechanism for both spirochetes and adult ticks. some tick larvae may acquire the spirochete by transovarial passage and the nymphal stage may transmit the disease to humans.19836836274
[chronic erythema migrans and tick-transmitted meningopolyneuritis (garin-bujadoux-bannwarth): borrelia infections?].antibodies against borrelia duttoni using indirect immunofluorescence could be demonstrated in 6 patients with erythema chronicum migrans and in 8 persons with tick-borne meningopolyneuritis. significant increases of igg and igm antibody titres in the course of the disease and igg antibodies in the csf indicate recent contact with borrelia duttoni or a closely related agent. demonstration by fluorescence serology of spirochaetaceae in ixodes ricinus in two sites of infection equally indicate suc ...19836839977
bacteriophage in the ixodes dammini spirochete, etiological agent of lyme disease.a bacteriophage with a b-3 morphology was detected by electron microscopy in a spirochete isolated from the tick ixodes dammini. it has a 40- to 50-nm elongated head and a tail 50 to 70 nm in length. it appears devoid of collars or kite-tail structure. the spirochete has been identified as the causative agent of lyme disease.19836853449
spirochetes in ixodes dammini and mammals from connecticut.spirochetes were observed in the midguts of 35% of 147 motile ixodes dammini from three locations in lyme and east haddam, connecticut. positive ticks were removed from eastern chipmunks (tamias striatus), raccoons (procyon lotor), white-footed mice (peromyscus leucopus), and a red squirrel (tamiasciurus hudsonicus). spirochetes were isolated in fortified kelly's medium from nine questing or partially engorged i. dammini adults and nymphs and from the bloods of a raccoon and a white-footed mouse ...19836881431
the spirochete in erythema chronicum migrans. demonstration by light and electron microscopy.a lesion of erythema chronicum migrans was examined by light and electron microscopy. spirochetes were identified by light microscopy with steiner silver stain. electron microscopy was performed on deparaffinized tissue of the biopsy specimen and a spirochete was identified in the tissue. this treponema-like spirochete has morphological characteristics similar to those described previously for spirochetes obtained from ticks in areas endemic for lyme disease.19836881479
[the spirochetal etiology of erythema chronicum migrans and garin-bujadoux-bannwarth meningo-polyneuritis].erythema chronicum migrans and tick-born meningo-polyneuritis garin-bujadoux-bannwarth are caused by a spirochete transmitted by ixodes ricinus. the same is true of lyme disease, the erythema chronicum migrans infection of north america transmitted by ticks of the same genus. in europe demonstration of igg and igm antibodies against borrelia duttoni during the course of infection and by immunofluorescence staining of spirochetes in ticks at sites of infection indicate this etiology. in the usa a ...19836884950

spirochetes isolated from the blood of two patients with lyme disease.we isolated spirochetes from the blood of 2 of 36 patients in long island and westchester county, new york, who had signs and symptoms suggestive of lyme disease. the spirochetes were morphologically similar and serologically identical to organisms recently found to infect lxodes dammini ticks, which are endemic to the area and have been epidemiologically implicated as vectors of lyme disease. in both patients, there was a rise in specific antispirochetal antibodies in paired specimens of serum. ...19836828119
the spirochetal etiology of lyme disease.we recovered a newly recognized spirochete from the blood, skin lesions (erythema chronicum migrans [ecm]), or cerebrospinal fluid of 3 of 56 patients with lyme disease and from 21 of 110 nymphal or adult lxodes dammini ticks in connecticut. these isolates and the original one from l. dammini appeared to have the same morphologic and immunologic features. in patients, specific igm antibody titers usually reached a peak between the third and sixth week after the onset of disease; specific igg ant ...19836828118
lyme disease: a selective medium for isolation of the suspected etiological agent, a spirochete.a simple procedure with a new selective culture medium for the isolation of the suspected etiological agent of lyme disease from ticks is described. live ticks (ixodes dammini) were ground with a mortar and pestle, and the suspensions were inoculated into a selective and nonselective medium. the selective medium, which contained kanamycin and 5-fluorouracil, yielded positive spirochete cultures from 100% of the pooled ticks and from 79% of the single tick specimens. the isolation rate for the no ...19846361065
[spirochete etiology of erythema chronicum migrans disease].from ticks of the type ixodes ricinus, 19 strains of a spirochete were isolated at three places of infection of erythema chronicum migrans disease. the spirochete was immunologically related to borrelia duttoni, treponema pallidum and ixodes dammini spirochete, the causative organism of north american erythema chronicum migrans disease (lyme disease). the isolated spirochete differed from the north american one in its reaction with monoclonal antibodies and possibly in its electronmicroscopic st ...19846363033
enzyme-linked immunosorbent assay and indirect immunofluorescence assay for lyme disease.the sensitivity and specificity of an indirect immunofluorescence assay (ifa) and elisa for lyme disease were estimated. sera from patients with lyme disease, patients with other infections, and healthy individuals were examined. significant cross-reactivity occurred only with sera from patients with syphilis, yaws, and pinta . all tested sera from patients with lyme disease, however, gave negative results in the rapid reagin screening test and the microhemagglutination assay for antibodies to t ...19846371156
antibody response in lyme disease: evaluation of diagnostic tests.the antibody response to the ixodes dammini spirochete was determined in 41 serial serum samples from 12 patients with lyme disease. by enzyme-linked immunosorbent assay (elisa), 11 of the 12 patients had higher titers of specific igm antibody (greater than 1:200) during early disease than did 40 control subjects. specific igm antibody titers, which correlated with total amounts of igm antibody (p less than .001), sometimes remained elevated throughout the illness. during neuritis, nine of 10 pa ...19846373966
comparison of an indirect fluorescent-antibody test with an enzyme-linked immunosorbent assay for serological studies of lyme enzyme-linked immunosorbent assay was compared with an indirect fluorescent antibody test for its ability to detect antibodies to the lyme disease spirochete in sera of naturally infected humans, dogs, and white-footed mice and experimentally infected swiss mice. ninety-five percent of the total 123 sera analyzed reacted similarly in both tests. for 36 human sera, the correlation coefficient (r = 0.47) for logarithmic transformations of indirect fluorescent antibody and enzyme-linked immunoso ...19846386843
interactions of phagocytes with the lyme disease spirochete: role of the fc receptor.the phagocytic capacity of murine and human mononuclear and polymorphonuclear phagocytes (including peripheral blood monocytes and neutrophils), rabbit and murine peritoneal exudate cells, and the murine macrophage cell line p388d1 against the lyme disease spirochete was studied. all of these cells were capable of phagocytosing the spirochete; phagocytosis was measured by the uptake of radiolabeled spirochetes, the appearance of immunofluorescent bodies in phagocytic cells, and electron microsco ...19846386995
taxonomy of the lyme disease spirochetes.morphology, physiology, and dna nucleotide composition of lyme disease spirochetes, borrelia, treponema, and leptospira were compared. morphologically, lyme disease spirochetes resemble borrelia. they lack cytoplasmic tubules present in treponema, and have more than one periplasmic flagellum per cell end and lack the tight coiling which are characteristic of leptospira. lyme disease spirochetes are also similar to borrelia in being microaerophilic, catalase-negative bacteria. they utilize carboh ...19846393605
the antibody response in lyme disease.we determined the antibody response against the ixodes dammini spirochete in lyme disease patients by indirect immunofluorescence and an enzyme-linked immunosorbent assay (elisa). the specific igm response became maximal three to six weeks after disease onset, and then declined, although titers sometimes remained elevated during later disease. specific igm levels correlated directly with total serum igm. the specific igg response, often delayed initially, was nearly always present during neuriti ...19846393607
phagocytic cell responses to in vivo and in vitro exposure to the lyme disease experimental skin lesion induced in rabbits by the bite of infected adult ixodes dammini showed dense dermal interstitial inflammatory cell infiltrates composed of mononuclear cells (histiocytes and lymphocytes) and granulocytes. the prevalence of phagocytic cells in this experimental lesion motivated a study on the interactions of macrophages and neutrophils with lyme disease spirochetes. interactions as measured by uptake of radiolabeled spirochetes and by indirect immunofluorescence were e ...19846393611
the new zealand white rabbit: an experimental host for infecting ticks with lyme disease spirochetes.efficiency of the new zealand white rabbit as a host for infecting larval ixodes dammini, i. pacificus, and i. ricinus with lyme disease spirochetes was evaluated. rabbits inoculated with infected midgut suspensions of i. dammini from shelter island, new york, or fed upon by infected ticks from the same area, responded with spirochetemias of sufficient concentrations to infect as many as 30 percent of the ticks. when infected ticks were used as indicators, it appeared that spirochetemias persist ...19846393612
infection in rabbits with the lyme disease spirochete.of 33 rabbits inoculated with lyme disease spirochetes, two developed erythema chronicum migrans at the site of inoculation. spirochetes were seen in skin biopsies of one of the lesions with immunoperoxidase and warthin-starry stains. spirochetes were also recovered from the blood of two additional rabbits two weeks post-inoculation. these findings are characteristic of early lyme disease in humans.19846393613

[cardiac manifestations of lyme disease. apropos of 2 cases].lyme disease, a well-known entity in the united states, has featured only rarely in the french literature. we report two cases from the cardiology department with acute symptomatic atrio-ventricular block. the illness begins with migratory chronic erythema, which is the best marker of the condition. this is followed by neurological, joint and cardiac manifestations. cardiac involvement consists essentially in a-v block of varying severity, which rapidly regresses. until the recent discovery of t ...19846497303
human phagocyte interactions with the lyme disease spirochete.the interaction between human polymorphonuclear leukocytes and monocytes and the lyme disease spirochete was investigated by incubating phagocytes with microorganisms adherent to plastic or glass surfaces. both cell populations readily phagocytized and killed spirochetes, and antibodies facilitated but were not essential for phagocytosis.19846500703
lyme disease: a unique human model for an infectious etiology of rheumatic disease.lyme disease is a complex immune-mediated multi-system disorder that is infectious in origin and inflammatory or "rheumatic" in expression. through its epidemiologic characteristics, large numbers of a seasonally synchronized patient population are readily available for prospective study. lyme disease has a known clinical onset ("zero time"), marked by the characteristic expanding skin lesion, erythema chronicum migrans, and a clearly defined pre-articular phase. at least some manifestations of ...19846516449
chronic meningitis and lyme disease in sweden.we studied 35 patients with chronic meningitis. the neurological abnormalities included aseptic meningitis, cranial neuropathy (mostly facial palsy), motor and sensory peripheral radiculoneuropathy, and myelitis. neurological symptoms were sometimes preceded by erythema chronicum migrans or an insect bite and were often accompanied by fever, malaise, profound fatigue, and weight loss. the cerebrospinal fluid (csf) abnormalities consisted of a predominantly mononuclear pleocytosis, an elevated cs ...19846516451
vectorial capacity of north american ixodes ticks.ixodes dammini, the vector of lyme disease and babesiosis, is distributed in various locations in the northeastern quadrant of the united states and nearby canada. the life cycle of this tick, which includes larval, nymphal, and adult stages, spans at least two years. the tick over-winters between larval and nymphal feeding. horizontal transmission of pathogens is facilitated by a feeding pattern in which both the larval and nymphal stages feed on the white-footed mouse, peromyscus leucopus, and ...19846516453
discovery of the lyme disease spirochete and its relation to tick vectors.the various hypotheses concerning the etiologic agent of erythema chronicum migrans of europe and of lyme disease in the united states are reviewed, and an account of events that led to the discovery of the causative spirochetal agent in ixodes dammini is presented. spirochetes morphologically and antigenically similar, if not identical to, the organism detected in i. dammini were also found for the first time in ixodes pacificus and ixodes ricinus, the vectors hitherto incriminated, respectivel ...19846516454
dna characterization of lyme disease spirochetes.lyme disease spirochetes (lds) have phenotypic characteristics of both treponemes and borreliae. to ascertain whether one or more species of lds exist, as well as their taxonomic status, we determined the dna base (g + c) content for three strains of lds, the dna relatedness of ten strains isolated in the united states or europe, and the dna relatedness of lds to other spirochetes. the g + c content of the three lds strains was 28.1-29.0 mol%, most similar to those of borellia hermsii (30.6 mol ...19846516455
susceptibility of the lyme disease spirochete to seven antimicrobial agents.the antimicrobial susceptibility of five lyme disease spirochete strains (two human and three tick isolates) was determined. a macrodilution broth technique was used to determine on three separate test occasions the minimal inhibitory concentrations (mics) of seven antibiotics. the lyme disease spirochete was most susceptible to erythromycin with a mic of less than or equal to 0.06 micrograms/ml. the spirochete was also found to be susceptible to minocycline, ampicillin, doxycycline, and tetracy ...19846516457
the global distribution of lyme disease.following the original description of erythema chronicum migrans (ecm) in sweden in 1909, ecm became widely recognized in europe. the first reported case of ecm acquired in the united states occurred in 1969, and in 1975 the full symptom complex now known as lyme disease was recognized. in 1981, cases of lyme disease were recognized in yet a third continent, australia and, to date, cases acquired in at least 19 countries have been reported. beginning with the original case reported in sweden, cl ...19846516458
geographic distribution of humans, raccoons, and white-footed mice with antibodies to lyme disease spirochetes in indirect immunofluorescence test was used during 1982-1983 to identify antibodies to lyme disease spirochetes in humans, white-footed mice, and raccoons. serologic tests detected igm or total ig antibodies in serum samples from 67 persons. onset of illness, as marked by erythema chronicum migrans (ecm), occurred mainly during july and august. the majority of the persons with lyme disease lived in south central and southeastern connecticut. analyses also verified prior spirochetal infections i ...19846516459
avian and mammalian hosts for spirochete-infected ticks and insects in a lyme disease focus in connecticut.spirochetes and their vectors and reservoirs were studied in a lyme disease focus in east haddam, connecticut, from mid-may through september 1983. ixodes dammini subadults were comparable in number on white-footed mice (peromyscus leucopus) (means = 2.9 +/- 3.6 sd) to those on 27 different species of birds (means = 2.3 +/- 4.2 sd) representing 11 families within the order passeriformes. less commonly found ticks on birds (means less than or equal to 0.1) were immature ixodes dentatus and haemap ...19846516460
prevalence of the lyme disease spirochete in populations of white-tailed deer and white-footed mice.the prevalence of the ixodes dammini spirochete (ids) in white-tailed deer (odocoileus virginianus) and white-footed mice (peromyscus leucopus) was studied on the eastern end of long island, new york. both species commonly occur in a variety of habitats, are preferred hosts of ixodes dammini, and can harbor the spirochetes in the blood. each animal was examined for spirochetemia, tick infestation, and ids infection rates in the ticks that were removed from it. the results obtained suggest that i ...19846516461
[etiology of erythema migrans disease and lyme disease. review and results of personal study].erythema chronicum migrans (ecm), lymphadenosis cutis benigna and acrodermatitis chronica atrophicans (aca) have been well known in europe for a long time as skin diseases induced by tickbites. earlier hints that these inflammatory dermatoses and associated disorders (erythema migrans disease) might be of spirochetal origin are now supported by the findings of several groups in the usa and europe. in the united states the endemic occurrence of a new inflammatory disease which seems to be closely ...19846519987
infection of syrian hamsters with lyme disease spirochetes.syrian hamsters were shown to be susceptible to infection by the lyme disease spirochete borrelia burgdorferi. although these spirochetes did not cause any outward signs of illness in these animals, they did cause a generalized infection. spirochetemia was present during the first 6 days of infection. at 14 days postinfection, spirochetes could be isolated from one or more of the following organs: spleen, eyes, kidneys, liver, testes, and brain. spirochetes were isolated from the eyes and kidney ...19846520220
