isolation of borrelia burgdorferi from peromyscus leucopus in oklahoma.	borrelia burgdorferi was isolated from a field-caught peromyscus leucopus from central oklahoma (usa). the strain was identified as b. burgdorferi by reaction with monoclonal antibody h5332 specific for the outer surface protein ospa of b. burgdorferi. this represents the first isolation of b. burgdorferi from a wild mouse outside of the normal range of the known vectors ixodes dammini and i. pacificus.	1992	1602581
[pigmented urticarial erythema with flaccid atrophy as expression of an unusual manifestation of lyme borreliosis].	unusual courses of infections with borrelia burgdorferi can make diagnosis problematic, but early and adequate therapy is mandatory to avoid further complications. in this paper a patient is presented who developed urticarial erythemas and hyperpigmentation with slack skin atrophy. positive serological findings and the regression of the skin eruptions under antibiotic therapy confirmed the diagnosis of an unusual manifestation of lyme borreliosis.	1992	1548134
structural analysis of an outer surface protein from the lyme disease spirochete, borrelia burgdorferi, using circular dichroism and fluorescence spectroscopy.	the etiological agent of lyme disease is the tick-borne spirochete, borrelia burgdorferi. a major antigen of b. burgdorferi is a 31 kda lipoprotein called outer surface protein a (ospa). recently, a truncated form of ospa (lacking 17 amino acids at the n-terminus) was cloned, expressed and purified in large quantities (dunn, j.j., lade, b.a. and barbour, a.g. (1990) protein expression and purification 1, 159-168). the truncated protein (ospa-257) is water-soluble, retains the ability to bind ant ...	1992	1554741
adherence and entry of borrelia burgdorferi in vero cells.	adherence to and entry of the parasite into the host is one of the essential elements of microbial pathogenicity. we investigated the adherence to and entry into primate kidney epithelial (vero) cells of borrelia burgdorferi by radiolabelling techniques, immunofluorescence and electronmicroscopy. the attachment to and subsequent entry of both untreated and heat (50 degrees c)-treated b. burgdorferi into vero cells occurred at cell-surface sites associated with aggregated coated pits. in contrast ...	1992	1560445
long-term protection of mice from lyme disease by vaccination with ospa.	mice vaccinated with recombinant outer surface protein a (ospa) have been shown to be protected from infection with borrelia burgdorferi, the agent of lyme disease, when sacrificed 14 days after challenge with an intradermal inoculum of the spirochete. to determine whether infection was not merely delayed and that protection was long-lasting, we sacrificed vaccinated mice 60, 120, and 180 days after challenge; and to determine whether vaccinated mice retained their immune state over long periods ...	1992	1541551
tandem repeat of the 23s and 5s ribosomal rna genes in borrelia burgdorferi, the etiological agent of lyme disease.	the dna fragments containing the rrl and rrf genes were subcloned from a embl3 recombinant phage of borrelia burgdorferi strain b31 into puc18 and were characterized by restriction analysis and southern hybridization. a fine restriction map of the fragments was constructed and the organization of the genes was determined. the genomic hybridization using the gene probes from b. burgdorferi showed that there are two sets of rrl/rrf genes in that genome. the results also revealed the important fact ...	1992	1567408
molecular diagnosis of borrelia burgdorferi infection (lyme disease).	in spite of significant advances in immunologically based testing, accurate diagnosis of lyme borreliosis remains problematic. to address this issue, a dna amplification-based diagnostic test was developed utilizing the polymerase chain reaction (pcr) and oligonucleotide primers specific for the ospa and ospb genes of borrelia burgdorferi. in this approach, a relatively large dna fragment is amplified with an outer set of primers, and a "nested" internal sequence of the pcr product subsequently ...	1992	1567553
heterogeneity of outer membrane proteins in borrelia burgdorferi: comparison of osp operons of three isolates of different geographic origins.	biochemical and immunochemical studies of the outer membrane proteins of borrelia burgdorferi have shown that the ospa and ospb proteins from strains of different geographic origins may differ considerably in their reactivities with monoclonal antibodies and in their apparent molecular weights. to further characterize this variation in osp proteins between strains, the osp operons and deduced translation products from two strains, one from sweden (acai) and one from eastern russia (ip90), were s ...	1992	1563773
[positive anti-borrelia antibodies in patients with clinical manifestations compatible with neuroborreliosis].	the clinical features of 19 patients with neurological manifestations unexplained by another disease and positive serology for borrelia burgdorferi were studied. ecm was present in only 11% of the cases and 32% referred tick bite. the characteristic features for suspicion of nb according to our series was the presence of polyneuritis in 84% of the cases specially in the form of multiple mononeuritis and involvement of the facial nerve (79%) leading to even greater suspicion with the association ...	1992	1610600
untreated neuroborreliosis: bannwarth's syndrome evolving into acute schizophrenia-like psychosis. a case report.	in general, meningopolyradiculitis (bannwarth's syndrome, stage 2 of neuroborreliosis) follows a predictable monophasic self-limiting course. in contrast, we report the case of a patient with an untreated meningopolyradiculitis which evolved into acute schizophrenia-like psychosis due to persistent infection with borrelia burgdorferi. the psychosis resolved within 1 week of treatment with ceftriaxone. this case shows that the usually benign monophasic meningopolyradiculitis may progress to sever ...	1992	1573415

babesiosis: an underdiagnosed disease of children.	babesiosis is a malaria-like illness caused by the intraerythrocytic parasite babesia microti and is transmitted by the same tick that transmits borrelia burgdorferi, the causative agent of lyme disease. babesiosis is well recognized in adult residents of southern new england and new york but has been described in only five children. to determine whether children are infected with b microti less often than are adults, a prospective serosurvey was carried out on block island, ri, where babesiosis ...	1992	1594345
first isolation of borrelia burgdorferi in southern california.	the lyme disease spirochete, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, was isolated from the blood of a dusky-footed wood rat, neotoma fuscipes baird, in the san bernardino mountains of southern california. antigenic, protein, and molecular analyses demonstrated that the isolate varied slightly from most isolates of b. burgdorferi from northern california and was clearly distinct from other species of borrelia that are endemic to the state. this is the first reported iso ...	1992	1625299
inability of ixodes cookei and amblyomma americanum nymphs (acari: ixodidae) to transmit borrelia burgdorferi.	the vector competency of ixodes cookei packard and amblyomma americanum (l.) for borrelia burgdorferi was studied using syrian hamsters. ixodes dammini spielman, clifford, piesman & corwin were used as controls. darkfield and immunofluorescent examinations of midgut diverticula revealed b. burgdorferi spirochetes in 32 of 36 (88.9%) i. dammini larvae, 5 of 36 (13.9%) i. cookei larvae, and 7 of 36 (19.4%) a. americanum larvae within 48 h after feeding on infected syrian hamsters. b. burgdorferi w ...	1992	1625302
effectiveness of an aerial application of carbaryl in controlling ixodes dammini (acari: ixodidae) adults in a high-use recreational area in new jersey.	lyme disease risk reduction through the control of the principal tick vector, ixodes dammini spielman, clifford, piesman & corwin, has become a major issue facing public health agencies in many endemic states. where large tracts of land are involved, established methods of i. dammini control are impractical. an aerial application of carbaryl directed against fall populations of i. dammini adults resulted in 93.8% control after 96 h. control persisted through the following spring. the usefulness ...	1992	1625304
serological survey for lyme disease in domestic dogs and white-tailed deer from oklahoma.	sera from 223 randomly selected dogs and 489 white-tailed deer (odocoileus virginianus) were tested for antibodies to borrelia burgdorferi using an indirect kinetic elisa. dog samples were obtained in 1989 whereas deer samples were obtained between 1975 and 1990. ten known negatives and two known positives from each group were run on each plate as controls. samples showing mean mod values above the mean of negatives + 3 sd were considered positive. twenty-six dog (11.7%) and 22 deer (4.5%) sampl ...	1992	1626867
prevention of lyme disease.	lyme disease and the use of tick repellents and physical protective measures to prevent the disease are discussed. lyme disease is a multiple-organ-system, immune-mediated inflammatory disorder transmitted by the bites of ixodid ticks infected with borrelia burgdorferi. an individual is at greatest risk for infection when a tick has been attached to the skin for more than 24 hours. lyme disease occurs in three stages and may affect the skin, nervous system, cardiac system, and joints. antimicrob ...	1992	1595748
detection of borrelia burgdorferi in human blood and urine using the polymerase chain reaction.	we investigated the use of the polymerase chain reaction (pcr) to detect borrelia burgdorferi strain b-31 in human blood and urine experimentally inoculated with 5 and 1 borreliae/cm3, respectively, and to biotinylate a dna probe specific for b. burgdorferi in the dot blot and southern blot assays. when the blood and urine samples were subjected to pcr, a 370-bp amplified product was consistently visible on agarose gel electrophoresis after 30 and 45 cycles, respectively. the total human genomic ...	1992	1627262
detection of borrelia burgdorferi dna in urine samples and cerebrospinal fluid samples from patients with early and late lyme neuroborreliosis by polymerase chain reaction.	a polymerase chain reaction (pcr) was developed for use in the identification of a 248-bp fragment of the borrelia burgdorferi flagellin gene in urine and cerebrospinal fluid (csf) from patients with lyme neuroborreliosis. the specificities of the pcr products were confirmed by dna-dna hybridization with an internal probe. the assay had a detection limit of 10 in vitro-cultivated b. burgdorferi. the pcr assay seemed to be species wide as well as species specific, since dna from all 21 b. burgdor ...	1992	1629318
interactions between extracellular borrelia burgdorferi proteins and non-borrelia-directed immunoglobulin m antibodies.	previous work showed that outer surface protein a (ospa) and ospb of borrelia burgdorferi may occur within an extracellular multiprotein complex, which was resolved by electrophoresis as an 83-kda major extracellular protein band. to characterize the 83-kda band, we sequenced the n terminus of the predominant peptide in the band and examined the interaction between the associated proteins. peptide sequence and amino acid composition comparisons showed identity with the heavy chain of immunoglobu ...	1992	1541558
epidemiology and prevalence of seropositivity against borrelia burgdorferi antigen in la rioja, spain.	the aim of this study was to acquire a better knowledge of the epidemiology of lyme disease. a seroepidemiologic study was made by evaluating the different levels of antibodies to borrelia burgdorferi in a five hundred serum representative sample of a population from the province of la rioja, spain. samples were randomly selected and stratified to take into account sex, age, rural or urban residence, and geographical area. all subjects included in the study were asked to fill out a questionnaire ...	1992	1631381
diagnosing lyme disease.	the incidence of lyme disease is increasing, and the disease is spreading geographically. prompt diagnosis requires recognition of characteristic signs and symptoms of infection with the spirochete borrelia burgdorferi. in more than half of cases, erythema migrans is the earliest sign of lyme disease. although less frequently seen than erythema migrans, peripheral neuropathy of the seventh cranial nerve is another important sign. tests for lyme disease await refinement, but laboratory evaluation ...	1992	1575110
fibroblasts protect the lyme disease spirochete, borrelia burgdorferi, from ceftriaxone in vitro.	the lyme disease spirochete, borrelia burgdorferi, can be recovered long after initial infection, even from antibiotic-treated patients, indicating that it resists eradication by host defense mechanisms and antibiotics. since b. burgdorferi first infects skin, the possible protective effect of skin fibroblasts from an antibiotic commonly used to treat lyme disease, ceftriaxone, was examined. human foreskin fibroblasts protected b. burgdorferi from the lethal action of a 2-day exposure to ceftria ...	1992	1634816
antibiotic treatment of lyme disease. current recommendations by stage and extent of infection.	much has been learned about lyme disease over the past several years, but much remains to be learned. careful clinical observation has led to elucidation of the natural history of this disease, and further clinical observations are needed to unravel the remaining areas of uncertainty. it is by no means clear that all the symptoms attributed to lyme disease today actually represent true manifestations of borrelia burgdorferi infection or that patients with well-documented lyme disease whose sympt ...	1992	1589368
special concerns in lyme disease. seropositivity with vague symptoms and development of fibrositis.	fear of lyme disease may be as powerful as the disease itself. patients may insist on being tested for infection although little evidence of it exists, and a positive result in the face of vague symptoms can add to the problem. physicians should explain to these patients the differences in "background" seropositivity in various geographic locations and the drawbacks of instituting unnecessary treatment. fibrositis may evolve over time after lyme disease infection. many factors may trigger this d ...	1992	1589369
