lyme carditis: an important cause of reversible heart block.lyme disease is a tick-borne spirochetal infection, characterized by erythema chronicum migrans and an acute systemic illness. the disease is endemic in many parts of the north-eastern united states. without treatment, late rheumatic, neurologic, and cardiac complications frequently occur. we report four serologically confirmed cases of lyme carditis in previously healthy young men (mean age, 45 years) from endemic areas. each presented with severe symptomatic atrioventricular block, three with ...19892644885
spirochetal forms in the dermal lesions of morphea and lichen sclerosus et atrophicus.morphea and lichen sclerosus et atrophicus are cutaneous diseases that are manifest by an early edematous stage, followed later by sclerosis and atrophy. they share features with acrodermatitis chronica atrophicans and erythema chronicum migrans, diseases that have been linked to infection by the spirochete borrelia burgdorferi. a modified silver stain was used to identify the presence of spirochetes in skin biopsy specimens of patients with morphea and lichen sclerosus et atrophicus. spirocheta ...19902393064
persistent atrioventricular block in lyme borreliosis.cardiac manifestations are reported in 0.3%-4.0% of european patients with borrelia burgdorferi (b.b.) infection. usually symptoms disappear within 6 weeks. we report a case with persistent impairment of atrioventricular (av) conduction. diagnosis was confirmed by demonstration of igm antibodies and increase of igg antibody titers against b.b. in serum, by isolation of the spirochete from skin biopsy material and by the typical clinical combination of erythema migrans, bannwarth syndrome (mening ...19902348647
lyme disease. employee education and treatment.lyme disease is a complex multisystem disorder that begins with the bite from the ixodes tick. the ixodes tick carries the spirochete, borrelia burgdorferi, and infects humans with the spirochete. the initial symptoms of lyme disease are the erythema chronicum migrans, or "bull's eye" rash, and flu-like symptoms. stage iii of lyme disease can occur weeks to months after the initial infection when more serious complications may develop, such as neurologic, cardiac, or ophthalmologic problems. if ...19902375798
monoclonal antibodies specific for the outer surface protein a (ospa) of borrelia burgdorferi prevent lyme borreliosis in severe combined immunodeficiency (scid) mice.we have recently shown that viable borrelia burgdorferi organisms induce a chronic infection associated with arthritis and carditis in severe combined immunodeficiency (scid) mice but not in immunocompetent mice. the disease is similar to that found in patients suffering from lyme disease. we now show that b. burgdorferi-specific immune mouse sera as well as a monoclonal antibody to the spirochetal outer surface antigen a (31 kda) but not monoclonal antibodies specific for the 41-kda antigenic c ...19902339119
status of ixodes dammini (acari: ixodidae) in illinois.ixodes dammini spielman, clifford, piesman & corwin was found for the first time in illinois in november 1987, when two adult females were collected from two deer in jo daviess county in the northwestern corner of the state. in 1988, in a study of six state parks in northern illinois, questing adults and nymphs were encountered in one park in ogle county. during the firearm deer hunt in november 1988, adult female and male ticks were found in several counties, with a high rate of infestation (gr ...19902388231
lyme borreliosis-associated encephalopathy.borrelia burgdorferi infection (lyme disease) is frequently accompanied by cns dysfunction. particularly common is a mild confusional state, the mechanism of which is unknown. since cns infection with b burgdorferi is usually accompanied by intrathecal synthesis of specific antibody, we studied csf in 73 patients referred for presumed cns lyme, manifested primarily as this confusional state. of 30 seropositive patients evaluated, only 5 had intrathecal antibody production. seven seronegative pat ...19902392213

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 ...19902295326
detection of borrelia burgdorferi dna in museum specimens of ixodes dammini order to investigate the potential for borrelia burgdorferi infection before the recognition of lyme disease as a clinical entity, the polymerase chain reaction (pcr) was used to examine museum specimens of ixodes dammini (deer ticks) for the presence of spirochete-specific dna sequences. one hundred and thirty-six archival tick specimens were obtained representing various continental u.s. locations; dna sequences characteristic of modern day isolates of b. burgdorferi were detected in 13 194 ...19902402635
[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 ...19902331826
[persistent leg pain].a 72 year old patient suddenly experienced severe lumbar pain irradiating into the right leg. later on, weakness of the muscles thigh appeared. a thorough radiological investigation which showed degenerative alterations of the vertebral column did not supply an explanation. after a pathological titer against borrelia burgdorferi was found in serum and radiculitis was detected on emg, the diagnosis of lyme-borreliosis of the nervous system could be confirmed by analysis of the cerebrospinal fluid ...19902142797

borrelia burgdorferi contains repeated dna sequences that are species specific and plasmid associated.borrelia burgdorferi, the causative agent of lyme borreliosis, contains linear and supercoiled circular (sc) plasmids. because sc plasmids are present in multiple copies, these plasmids were examined for species-specific sequences that could serve as high-copy-number target dnas for a diagnostic probe. three ecori fragments (4.3, 4.2, and 3.5 kilobase pairs [kb]) that hybridized with multiple dna fragments from b. burgdorferi were identified and cloned from a sc plasmid-enriched fraction. the 4. ...19902318533
borrelia burgdorferi myelitis presenting as a partial stiff man syndrome.eight weeks after a tick bite, a 33-year-old male patient presented with stiffness of one leg together with spasmodic painful jerks resembling stiff man syndrome. isolated myelitis of lumbosacral segments of the spinal cord, apparently confined to the grey matter, was diagnosed and its spirochaetal aetiology confirmed by serology and csf findings. oligoclonal igg bands in csf specific for borrelia burgdorferi were found. thus, there is evidence that b. burgdorferi ist able to cause a localized m ...19902319268
survival of borrelia burgdorferi in human blood stored under blood banking conditions.hematogenous dissemination of organisms occurs in many spirochetal diseases, including lyme disease and syphilis. although syphilis has been transmitted by transfusion, in the vast majority of cases, only fresh blood products were involved, in part because treponema pallidum survives poorly when refrigerated in citrated blood. because of the rising incidence of lyme disease in certain areas, whether its causative agent, borrelia burgdorferi, could survive under blood banking conditions was studi ...19902349627
computer simulation of rocky mountain spotted fever transmission by the american dog tick (acari: ixodidae).a computer model was developed for simulation of the transmission of rickettsia rickettsii, the causative agent of rocky mountain spotted fever (rmsf), by the american dog tick, dermacentor variabilis (say). the model of rmsf was combined with a model for population dynamics of the american dog tick and included simulation of infection and transmission of rickettsiae between ticks and host mammals and transmission of rmsf to humans. the model simulated the effects of biotic and environmental var ...19902388242
isolation, preliminary chemical characterization, and biological activity of borrelia burgdorferi peptidoglycan.peptidoglycan (pg), an essential cell wall polymer of most bacteria, has been isolated from many species of spirochetes. our interest in the host response to borrelia burgdorferi led us to isolate and characterize its pg. extracted cells were solubilized with warm 1% sds followed by digestion with proteases. amino acid analysis of the isolated pg demonstrated the presence of alanine, glycine, glutamic acid, and ornithine as occurs in other spirochetes and bacteria. intense erythematous reactions ...19902310405
thermoregulation of protein synthesis in borrelia burgdorferi.borrelia burgdorferi, the etiological agent of lyme disease, infects humans via the bite of a tick. the microbe survives in at least two vastly different environments: an arthropod vector and a warm-blooded host. we examined protein synthesis in b. burgdorferi b31 in response to sudden heat stress, which is similar to that which occurs during the transmission from vector to host. proteins synthesized after shifts from 28 degrees c to higher temperatures and in pulse-chase experiments were labele ...19902318529
[recent information on tick-borne diseases (i)].tick-borne encephalitis (central european encephalitis) and lyme disease (erythema chronicum migrans) are diseases mainly transmitted by ticks of the ixodes ricinus species. the tick-borne encephalitis, a virus infection, can produce severe encephalitic symptoms. there is no specific treatment but the infection can be prevented by active or passive immunization. lyme disease is caused by a spirochete (borrelia burgdorferi). due to the variety of often uncharacteristic symptoms this infection is ...19902158155
chronic neurologic manifestations of lyme disease.lyme disease, caused by the tick-borne spirochete borrelia burgdorferi, is associated with a wide variety of neurologic manifestations. to define further the chronic neurologic abnormalities of lyme disease, we studied 27 patients (age range, 25 to 72 years) with previous signs of lyme disease, current evidence of immunity to b. burgdorferi, and chronic neurologic symptoms with no other identifiable cause. eight of the patients had been followed prospectively for 8 to 12 years after the onset of ...19902172819
cefotaxime versus penicillin in the late stage of lyme disease--prospective, randomized therapeutic study.the low responsiveness of lyme arthritis to high dose intravenous penicillin g therapy has evoked the demand for new drugs for the treatment of late stage borreliosis. as can be deduced from in vitro susceptibility data, third generation cephalosporins are far more effective on borrelia burgdorferi spirochetes than penicillin g. the study presented here was designed to compare cefotaxime at a dosage of 2 x 3 g/day with penicillin g at a dosage of 2 x 10 megaunits/day, for ten days in a prospecti ...19902179134
effects of bovine serum albumin on the ability of barbour-stoenner-kelly medium to detect borrelia burgdorferi.the ability of decreasing inocula of borrelia burgdorferi to grow in otherwise identical barbour-stoenner-kelly (bsk) media containing different lots of bovine serum albumin (fraction v) was determined. these media differed significantly in ability to detect b. burgdorferi. some bsk media required inocula of 2 x 10(5) organisms per ml for detection, while other media could stimulate growth after inoculation with less than 2 organisms per ml. in addition, organisms from the less sensitive bsk med ...19902179264
[reflex sympathetic dystrophy. a new manifestation of lyme disease?].several syndromes derived from the involvement of central and peripheral nervous system and meninges have been reported in the infection by borrelia burgdorferi. the features of autonomic nervous system involvement have received a marginal attention. reflex sympathetic dystrophy is an autonomic picture characterized by regional sympathetic hyperactivity which has not been associated with lyme disease. we report a 16-year-old female with clinical, radiological and scintigraphic features consisten ...19902095902
