[the first results and objectives of the study of lyme disease in the ussr].	results of research on the prevalence, etiology, laboratory diagnosis, epidemiology, epizootology, and other aspects of lyme's disease, which was initiated in this country in 1984, are summed up. this borrelia-caused condition is now suggested to be a lead in morbidity rate among human diseases of natural nidus. the most topical, priority directions of further research are discussed.	1990	2220040
borrelia burgdorferi and babesia microti: efficiency of transmission from reservoirs to vector ticks (ixodes dammini).	in endemic regions, peromyscus leucopus, the mouse reservoir of the lyme disease spirochete (borrelia burgdorferi) and the piroplasm causing human babesiosis (babesia microti), is nearly universally infected with both agents. paradoxically, spirochetal infection is nearly twice as prevalent as is babesial infection in populations of field-collected nymphal ixodes dammini, the tick vector. in the laboratory, a similarly disproportionate rate of infection was observed among nymphal ticks, feeding ...	1990	2295326
incidence of tick-bite in man in aland islands: reference to the spread of lyme borreliosis.	the common tick ixodes ricinus is a vector both for the virus of tick-borne viral encephalitis (kumlinge disease, kd) and of borrelia burgdorferi (lyme borreliosis, lb). bites of the tick are believed to be common in aland, an island province of finland in the baltic sea. kd has been seen there for many years, and cases of lb have been diagnosed lately. the purpose of this study was to find the incidence of tick-bite among the population with possible implications for the spread of lb. a questio ...	1990	2320965
persistence of antibodies to borrelia burgdorferi in dogs of new york and connecticut.	multiple blood samples were obtained from privately owned dogs living in tick-infested areas of new york (westchester county) and connecticut, where lyme disease in human beings has been reported. of the 175 dogs examined, 127 (72.6%) had limb/joint disorder, whereas the remaining 48 dogs were considered healthy. results of analysis of 419 serum samples revealed igm antibody to borrelia burgdorferi in healthy and lame dogs during all seasons. prevalence of seropositivity was significantly (p les ...	1990	2329074
[a case of "neuralgic amyotrophy" with elevated serum antibody titer against borrelia burgdorferi].	a 39-year-old man experienced an abrupt onset of right back pain. the pain improved spontaneously, but weakness of the right upper extremity developed. the weakness deteriorated during the next month, and he was admitted to our hospital. neurological examination disclosed impairment of superficial sensation in his right upper extremity. blood examination showed no abnormal data. the cerebrospinal fluid was normal. neuroradiological findings were also negative. electrophysiological examinations w ...	1990	2331826
comparison of immunofluorescence and enzyme linked immunosorbent assays for diagnosing lyme disease.	a new enzyme linked immunosorbent assay (elisa) method was assessed in parallel with an indirect immunofluorescence assay (ifa) for the serological testing of specimens submitted for detection of lyme disease. wells of an elisa microtitre plate were coated with sonicated whole cells of borrelia burgdorferi in carbonate buffer. after overnight incubation at 4 degrees c the plates were washed three times, then incubated at 37 degrees c for an hour sequentially with a blocking solution, diluted tes ...	1989	2671054
identification and characterization of an endoflagellar antigen of borrelia burgdorferi.	the 41-kd antigen of borrelia burgdorferi is an immunodominant protein that is recognized early by antibodies in sera from lyme disease patients and known to be associated with the endoflagella. we identified the 41-kd endoflagellar antigen to be a single polypeptide with an apparent isoelectric point (pi) of 6.5 by two-dimensional (2-d) electrophoresis. this polypeptide, which we designated p41f alpha, was heavily labeled by 125i in 2-d autoradiographs of b. burgdorferi whole-cell lysates and w ...	1989	2738156
restriction endonuclease analysis of four borrelia burgdorferi strains.	a restriction endonuclease analysis was performed on four strains of borrelia burgdorferi: one isolated from man (sf), one from ixodes dammini (b31) and two from i. ricinus (bits in italy and b45 in germany). digestion by taq i and hae iii gave the best resolution of the dna fragments. three different restriction patterns were obtained: bits and b45 showed only one band difference. these results correlate with the reactivity of the four strains with monoclonal antibodies.	1989	2560664
human necrotizing splenitis caused by borrelia burgdorferi.	a 25-year-old hispanic male presented to the emergency room with complaints of severe left upper quadrant pain. physicians determined that the patient had an acute inflammatory process with a possible diagnosis of splenic abscess. a splenectomy was performed. histologic examination of the tissue sections revealed extensive necrosis and inflammation, but no etiologic agent was discernible. microbiologic cultures of the tissue had negative results. a dieterle silver stain revealed an overwhelming ...	1989	2648803
lyme disease.	lyme disease is of interest to the neurologist and neuroscientist for a variety of reasons. as more arthropod hosts throughout the world are infected with the causative organism, borrelia burgdorferi, the illness in humans is becoming more prevalent; in addition, recognition of the disease in humans and susceptible animals is increasing. the neurological manifestations include acute and chronic forms, and it has become clear that b. burgdorferi has joined treponema pallidum, herpes simplex virus ...	1989	2472690
temporary pacing in complete heart block due to lyme disease: a case report.	the authors present the case of a 44-year-old man who was admitted with complete heart block and signs of severe bradycardia. after steroid administration and temporary pacemaker treatment the complete heart block resolved. during this therapy transient st segment and t wave abnormalities occurred. the positive borrelia burgdorferi antibody titer arrived only after therapy had been completed. this is regarded as the first case of lyme carditis with complete heart block diagnosed in eastern europ ...	1989	2476769
antibodies to borrelia sp. in wild foxes and coyotes from wisconsin and minnesota.	serum samples from 93 red foxes (vulpes vulpes) and nine gray foxes (urocyon cinereoargenteus) trapped in wisconsin and 23 coyotes (canis latrans) trapped in wisconsin and minnesota were tested for antibodies to borrelia sp. with an indirect fluorescent antibody test which used borrelia burgdorferi as the whole-cell antigen. seven red foxes (8%) and two coyotes (9%) had antibody titers greater than or equal to 1:64. all the positive samples were from areas known to be endemic for human lyme dise ...	1989	2644451
role of immunoglobulin g in killing of borrelia burgdorferi by the classical complement pathway.	the antibody and complement requirements for killing of borrelia burgdorferi 297 by normal human serum (nhs) and nhs plus immunoglobulin g (igg) were examined. b. burgdorferi activated both the alternative and classical complement pathways in nhs. in nhs chelated with 10 mm ethylene glycol-bis(beta-aminoethyl ether)-n,n,n',n'-tetraacetic acid plus 4 mm mgcl2 (mg-egta) to block classical pathway activation, consumption (activation) of total hemolytic complement, complement component 3 (c3), and c ...	1988	3276623
[immunochemical analysis of the immune response in late manifestations of lyme borreliosis].	compared to american strains, european borrelia burgdorferi strains revealed considerable heterogeneity of major proteins. four strains isolated from ticks, human skin and human csf were selected from our 23 borrelia burgdorferi isolates. these strains and the american type strain b31 were characterized by sds-page (coomassie blue staining) and western blots (using rabbit immune sera against two of the strains and two monoclonal antibodies (h5323 and h3ts) against a major outer surface protein ( ...	1988	3381603
host responses to borrelia burgdorferi in dogs and horses.	by using paired sera the igm and igg host responses were analyzed in dogs with elisa and western blot techniques. antibodies in clinical seropositive dogs bound to 4-25 igm and up to 40 or more igg antigenic determinants. early igm response to the 41-kda flagellin persisted for at least 9 months and involved as many as seven other peptides. igg response expanded later in the disease and involved more immunogens than are currently recognized in late human disease. a percentage of asymptomatic dog ...	1988	3190094
[epidemiology of ixodes-borreliosis in southern germany].	intimate adaptation occurs between european strains of borrelia burgdorferi and the local hard tick ixodes ricinus. i. dammini, the important vector in usa, could not be infected experimentally with a strain of the lyme spirochete from southern germany. other species of blood suckers are sometimes able to maintain uptaken spirochetes for a few days, but never to compensate the tick vector. man seems to be a good host for b. burgdorferi but without epidemiological significance due to his poor vec ...	1987	3623604
electron microscopy studies of human intestinal spirochetes.	the ultrastructure of twenty human intestinal spirochetes was analyzed using the electron microscope. negatively stained cells were generally found to be loosely and irregularly waved. the isolates had cell dimensions ranging from 0.18-0.35 micron in width and from 3.9-14.2 micron in length. twin bundles of flagella were present in the space between the cytoplasmic membrane and the outer membrane. the majority of isolates had five flagella inserted sub-terminally at each cell end. human intestin ...	1987	3609249
arthritis caused by borrelia burgdorferi in dogs.	from october 1982 to may 1984, we studied 34 dogs from the lyme, conn area that had a history of tick exposure and lameness associated with pain, warmth, and/or swelling in one or more joints. large numbers of polymorphonuclear leukocytes were seen in giemsa-stained smears of synovial fluid from 9 dogs, and spirochetes (borrelia burgdorferi) were found in 1 sample by darkfield microscopy and immunoperoxidase techniques. the geometric mean antibody titer to b burgdorferi in the 34 dogs was 1:2,70 ...	1985	3997648
chemical and biologic characterization of a lipopolysaccharide extracted from the lyme disease spirochete (borrelia burgdorferi).	a lipopolysaccharide (lps) was isolated from the lyme disease spirochete by a modification of the hot phenol-water method. the material was composed of 45% carbohydrate, 8% protein, 44% lipid a, and 1% 3-deoxy-d-mannooctulosonic acid and accounted for approximately 1.5% of the cellular dry weight. the isolated lps possessed several biologic activities characteristic of endotoxins. the lps was pyrogenic for rabbits, mitogenic for human mononuclear cells and murine splenocytes, capable of clotting ...	1985	4008983
fatal pancarditis in a patient with coexistent lyme disease and babesiosis. demonstration of spirochetes in the myocardium.	a 66-year-old man developed fever, chills, myalgias, three erythematous skin lesions, and transient left eyelid lag. because of persistent fever, he was hospitalized 4 weeks after the onset of disease; a peripheral blood smear showed babesia microti in 3% of his erythrocytes. eighteen hours later, he died unexpectedly. autopsy showed pancarditis with a diffuse lymphoplasmacytic infiltrate, and spirochetes were found in the myocardium. antibody titers to both the lyme disease spirochete borrelia ...	1985	4040723
dna characterization of the spirochete that causes lyme disease.	lyme disease, a tick-borne disease long recognized in europe but only recently recognized in the united states, was shown in 1982-1983 to be caused by a spirochete, the lyme disease spirochete. whether one or more species of the spirochete exists is unknown, as is its taxonomic status. to answer these questions, we determined (i) the dna base (guanidine-plus-cytosine) content for five strains; (ii) the dna relatedness of 10 strains from europe or the united states (isolated from ticks, humans, a ...	1984	6490812
