susceptibility of iron-loaded borrelia burgdorferi to killing by hydrogen peroxide and human polymorphonuclear leucocytes.borrelia burgdorferi grew more slowly in iron-depleted than in iron-sufficient media. the addition of increasing concentrations of iron stimulated borrelial growth and resulted in the intracellular accumulation of this element. compared with iron-starved borrelia, iron-enriched organisms showed enhanced sensitivity to hydrogen peroxide. intracellular iron-content did not, however, influence susceptibility to killing by human polymorphonuclear leucocytes [corrected].19911874405
lyme borreliosis: detecting the great imitator.lyme disease is a common inflammatory disease of north america. it is caused by the spirochetal bacterium borrelia burgdorferi, which is transmitted by the bite of a small tick, ixodes dammini. the disease is inconsistent in its manifestation, mimicking a wide variety of maladies, many of which are noninfectious. currently, there is no practical means for detection of the presence of the organism, and serologic studies offer the best diagnostic aid. high titers of either immunoglobulin g (igg) o ...19911874654
wood rats and kangaroo rats: potential reservoirs of the lyme disease spirochete in california.the etiologic agent of lyme disease, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, was isolated repeatedly from dusky-footed wood rats, neotoma fuscipes baird, and california kangaroo rats, dipodomys californicus merriam, in northern california. all animals were collected in a region endemic for lyme disease but for which the natural reservoir of b. burgdorferi was unknown. similar attempts to isolate spirochetes from lizards, other species of rodents, jack rabbits, and deer ...19911875357
detection of borrelia burgdorferi in cerebrospinal fluid by the polymerase chain reaction.the polymerase chain reaction (pcr) was used to amplify specific dna sequences from different clinical isolates of borrelia burgdorferi and from cerebrospinal fluid (csf) of two patients with lyme disease of the central nervous system. the amplification products were separated by polyacrylamide gel electrophoresis and visualised by ethidium bromide staining. the definitive identification of amplified dna as a part of the b. burgdorferi flagellin gene was achieved by hybridisation to a 40-base ol ...19911875398

borreliosis risk after tick bite in north-eastern italy.lyme borreliosis is an infectious disease caused by the borrelia burgdorferi spirochete transmitted to man by a tick bite. the aim of this study was to assess the predictive value of tick bites for the diagnosis of borreliosis in a sample of 266 subjects residing in an endemic area of north-eastern italy. in the serological diagnosis of borreliosis, positive and negative predictive values of tick bites were found to be 24% and 88% respectively.19911921746
[endogenous paranoid-hallucinatory syndrome caused by borrelia encephalitis].we describe a case with no neurological signs but marked psychiatric symptoms induced by borrelia burgdorferi, whose clinical picture was indistinguishable from an endogenous schizophrenia. the symptoms within one week under antibiotic treatment with ceftriaxon, but afterwards the patient showed a mild organic brain syndrome. the case demonstrated the aetiologic nonspecificity of paranoid symptoms and hallucinations and emphasizes that in psychotic patients without psychiatric history additional ...19911922585
central nervous system abnormalities in lyme neuroborreliosis.intrathecal production of anti-borrelia burgdorferi antibody occurs frequently in cns lyme, yet reliable diagnosis of neuroborreliosis is still considered difficult and controversial. therefore, we assessed the utility of this measurement in 103 lyme patients. among 15 patients with lyme meningoradiculitis and 41 controls, diagnostic specificity was 93% and sensitivity 87%. application of this method permits the identification of a rare b burgdorferi-associated multifocal encephalitis (brain inf ...19911922798
plagues--what's past is present: thoughts on the origin and history of new infectious diseases.medical science has made tremendous strides in overcoming infectious diseases in the 20th century. despite this, several epidemics of previously unrecognized diseases have occurred during the last 15 years. these diseases include lyme disease, legionnaires' disease, toxic shock syndrome, and aids. examination of past epidemics, including the plague of athens, the black death, syphilis, and influenza, suggests that the sudden occurrence of diseases that were previously unrecognized is not unusual ...19911925288
life-threatening complications of empiric ceftriaxone therapy for 'seronegative lyme disease'.lyme disease, now the most common tick-borne illness in the united states, has recently received much media attention, due in part to its potentially serious sequelae in untreated patients. because a rare patient with late illness may lack antibodies to the etiologic agent, borrelia burgdorferi, physicians may be tempted to give empiric antibiotics for illnesses that may not be lyme disease. we have described a patient who, despite negative laboratory evidence for late lyme disease, was treated ...19911925730
