neurological manifestations of lyme disease.neurological disorder may be the initial manifestation of lyme disease. six cases of neurological lyme disease have been seen in the years 1986-89, five of whom contracted the disease in the west of ireland. three presented with a radiculoneuropathy, one with myalgia/fatigue and one with bilateral sixth nerve palsies and ataxia. these cases indicate the spectrum of neurological involvement of lyme disease in ireland which reflects that seen in europe. they also highlight some of the problems in ...20072045261
lyme disease surveillance--united states, 1989-1990.surveillance for lyme disease (ld) was initiated by cdc in 1982 (1), and in january 1991, ld became nationally reportable (2). forty-six states reported cases in 1989 and 1990 (figure 1), but the occurrence in nature of the causative bacterium, borrelia burgdorferi, has not been documented in all of these states. from 1982 through 1989, the annual reported number of cases of ld increased 18-fold (from 497 to 8803, respectively) and from 1986 through 1989, nearly doubled each year (figure 2). the ...19912046649
lyme disease. difficulties in diagnosis and is a multisystem illness caused by the spirochete b. burgdorferi. as with other spirochetal diseases, lb evolves in stages. some manifestations are the result of persistent infection, whereas other symptoms are a consequence of immunologic changes secondary to the infection. most disease manifestations are not specific to this illness. in addition, in endemic areas, almost 100% of the tick vector, the ixodes species, are infected and the incidence rate of lb is as high as 1%. because of these ...19912047137

lyme borreliosis in selected strains and ages of laboratory mice.the susceptibility of laboratory mice to borrelia burgdorferi was evaluated for selected genotypes and ages. c3h/he, swr, c57bl/6, sjl, and balb/c mice inoculated at age 3 days developed uniformly severe polyarthritis at 30 days after intraperitoneal inoculation. mice inoculated at age 3 weeks also developed polyarthritis, but severity was influenced by genotype, with c3h/he and swr mice the most severely affected. susceptible strains developed higher igg elisa antibody titers to b. burgdorferi ...19902141344
cogan's syndrome and seroreactivity to lyme borreliosis.we document the case of a young woman with bilateral nonluetic, interstitial keratitis, vestibuloauditory problems, and bilateral recurrent facial palsies, who had strongly positive serologic tests of lyme borreliosis. to our knowledge, this is the first reported case of positive serologic tests for borrelia burgdorferi in a patient with cogan's syndrome.19902141863
susceptibility of laboratory rats to isolates of borrelia burgdorferi from different geographic week old lew/n rats were inoculated with 15 different isolates of borrelia burgdorferi from 3 major north american (northeast, midwest, and pacific) and 1 european endemic areas. at 30 days after inoculation, several tissues were cultured for b. burgdorferi and examined for histopathological changes. sera were tested for igm and igg antibody to b. burgdorferi by an enzyme-linked immunosorbent assay. one or more isolates from each geographic region was recovered by culture and caused arthriti ...19902142584
[occurrence of borrelia antibodies in field hares (lepus europaeus)].using the indirect haemagglutination reaction with an antigenic extract from borrelia recurrentis, the author assessed in the hare the incidence of borrelia antibodies, incl. antibodies against borrelia burgdorferi, the causal agent of lyme borreliosis, a multisystemic disease with natural foci, a disease transmitted mostly by ticks of the genus ixodes. sera of 113 hares from 11 localities in the cssr examined by this method reacted in 41.6% by titres within the range from 1 : 16 to 1 : 512, onl ...19902142623
[natural foci of lyme borreliosis].the submitted paper provides evidence that tick-borne borreliosis described as lyme disease, is a disease with natural focality. its properties, despite the widespread occurrence, classify it in this group. the authors give a characteristic of the disease, of hitherto known vectors, the main reservoir animals in america and europe. attention is drawn to the importance of deer and the effect of their increasing numbers on the spread of ticks and the disease. the great adaptability of the causal a ...19902142627
[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
lyme borreliosis in laboratory animals: effect of host species and in vitro passage of borrelia burgdorferi.the susceptibility of several common laboratory animal species to a known pathogenic isolate of borrelia burgdorferi (n40) was evaluated following intraperitoneal (ip) inoculation of 10(6-8) spirochetes into 3-day-old lewis rats, cd-1 mice, syrian hamsters, and 3-week-old american dutch rabbits. at 30 days, tissues were cultured for spirochetes and examined histologically. all species developed multisystemic infection as well as arthritis and carditis, but disease was most severe in rats and mic ...19902143358
lyme disease: a seasonal hazard.cutaneous markers are usually the first signs of lyme disease, a multisystem infection that affected about 7,000 people last year. this article reviews its clinical features, diagnosis, and treatment.19902144434
in-vitro and in-vivo susceptibility of borrelia burgdorferi to azithromycin.the in-vitro and in-vivo susceptibility of borrelia burgdorferito tetracycline, erythromycin and azithromycin was investigated. a macrodilution broth technique was used to determine mbcs. b. burgdorferi was most susceptible to azithromycin (mbc 0.04 mg/l) followed by erythromycin (mbc 0.16 mg/l) and tetracycline (mbc 1.6 mg/l). syrian hamsters were used to determine ed50s for the three antimicrobials. azithromycin was most effective in the elimination of spirochaetes from experimentally infected ...19902154436
saliva of the tick ixodes dammini inhibits neutrophil function.pilocarpine-induced saliva of adult female ixodes dammini ticks inhibits the function of peritoneal-derived rat neutrophils, as measured by anaphylatoxin-induced aggregation, fmlp-induced granule enzyme secretion, zymosan-induced superoxide secretion, and phagocytosis of borrelia burgdorferi spirochetes. inhibition ranged from 40 to 80% when saliva was diluted 20 times into the assay medium. this neutrophil-inhibiting activity of i. dammini saliva may aid in tick feeding and facilitate pathogen ...19902157607
[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

lyme neuroborreliosis. peripheral nervous system ever increasing number of apparently unrelated peripheral nervous system (pns) disorders has been associated with lyme borreliosis. to ascertain their relative frequency and significance, we studied prospectively 74 consecutive patients with late lyme disease, with and without pns symptoms: 53% had intermittent limb paraesthesiae, 25% the carpal tunnel syndrome, 8% painful radiculopathy, and 3% bell's palsy; 39% had disseminated neurophysiological abnormalities. to assess the interrelationshi ...19902168778
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
early diagnosis of enteroviral meningitis by a solid-phase reverse immunosorbent test and virus isolation.45 cases of aseptic meningitis/meningoencephalitis were studied with regard to enteroviral etiology by virus isolation and solid-phase reverse immunosorbent test (sprist), a cross-reacting test for enterovirus igm. an etiological diagnosis was reached in 37/45 (82%) patients. etiological diagnoses other than enteroviruses were found in 8 patients: borrelia burgdorferi in 4, varicella-zoster virus in 2, herpes simplex virus in 1 and mumps virus in 1 patient. enteroviruses (echovirus 6, 21 and 30) ...19902175448
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
