seroconversion to borrelia burgdorferi in a patient with juvenile arthritis in ontario, canada.a seroconversion to borrelia burgdorferi, the etiological agent of lyme disease, was documented in a 5 year old girl from central ontario. our patient developed juvenile arthritis in january, 1984 when she was 14 months old. it was relatively well controlled with aspirin. her arthritis flared in april, 1986 at which time seroconversion to b. burgdorferi was demonstrated by indirect immunofluorescence and by enzyme linked immunosorbent assay. she was treated with phenoxymethyl penicillin and has ...19883204603
[antibody activity of csf oligoclonal igg in infectious neurological diseases. detection using immunoblotting].the authors describe various applications of an immunoblot technique which allows the qualitative determination of the specific antibody activity of oligoclonal igg intrathecally synthesized in infectious diseases of the nervous system. after dilution of sera to the same igg concentration as the paired csf samples, 10 microliters of both fluids are applied side by side on agarose gel plates and isoelectrically focused. precipitated igg or specific igg antibodies are then blotted onto a nitrocell ...19883206996
the significance of eperythrozoon ovis in ill-thrift in sheep in the eastern cape coastal areas of south africa.ill-thrift in sheep in the coastal region of the eastern cape is described. it is shown to be a complex problem attributable to many causes, most of which can be eliminated by supplementary feeding, drenching, vaccination, dipping and management. however, studies on the aetiology of ill-thrift in young sheep indicate that arthropod-borne anaemia-producing pathogens are an important contributing factor, which cannot readily be diagnosed and controlled. experiments were conducted on various farms ...19883210217
first isolation of borrelia burgdorferi, the agent of lyme borreliosis, from ixodes ricinus (acari: ixodidae) in berlin (west).in 1984, two human cases of tick-borne lyme borreliosis with considerable neurologic involvement were reported in berlin (west). the diagnosis of lyme borreliosis was serologically confirmed. the ticks which had transmitted the borrelia were from berlin (west). in the autumn of 1985, 156 ticks were collected in forests of berlin (west) for the cultural detection of spirochetes by using bsk ii medium. three strains of spirochetes were isolated (from a pooled sample of two nymphs, and samples of o ...19883213319
infections following tickbites. tick-borne encephalitis and lyme borreliosis--a prospective epidemiological study from tyrol.we present here a prospective study on infections following tickbites in military recruits in the province of tyrol (austria). 84 recruits experienced tickbites and underwent clinical and serological examination twice at four-week intervals for signs of tick borne encephalitis (tbe)-virus or borrelia burgdorferi infections. 56 and 50 recruits could be evaluated for tbe-virus and borrelia infection, respectively. whereas no recruit was found with clinical or laboratory evidence of tbe-virus infec ...19883215687
[the effectiveness of ciprofloxacin in bacterial skin infections].ciprofloxacin in a low dosage of 250 mg twice a day was applied in the treatment of bacterial infections of the skin. all cultured staphylococci, streptococci, and pseudomonas proved to be highly sensitive to ciprofloxacin. the cases of pyoderma showed quick healing, but there were relapses of lyme borrelia within 6 weeks. as the titers of igm and igg steadily increased during the following months, additional therapy was necessary. the tolerance of ciprofloxacin was generally very good.19883218288
lyme disease meningopolyneuritis simulating malignant lymphoma.lyme disease is a multisystem disorder resulting from infection by the tick-borne spirochete, borrelia burgdorferi. fever, chills, malaise and headaches; a characteristic rash; and subsequent polyarthritis typically herald the onset of this condition. neurologic involvement may occur with skin and joint manifestations or present alone as meningitis, cranial neuritis, and radiculopathy known as bannwarth's syndrome. we report the cerebrospinal fluid (csf) cytomorphologic and immunocytochemical fe ...19883222255

[lymphocytic meningoradiculitis (bannwarth's syndrome). neurologic involvement of lyme disease].we describe a patient with lyme's disease who showed neurologic symptoms of meningoradiculitis (bannwarth's syndrome) and had no previous history of exposure to tick bite or chronic erythema migrans. he had longterm fever and bilateral facial paralysis. antibody titres for borrelia burgdorferi in serum and cerebrospinal fluid (csf) were increased. the csf changes showed an intrathecal production of immunoglobulins (presence of plasmatic cells and immunoblasts; igg-csf: igg-serum ratio much highe ...19892490177
[prevalence of antibodies against borrelia burgdorferi among the population of seville].in order to determine the prevalence of antibodies against borrelia burgdorferi in the area of sevilla, we have studied 300 healthy subjects of different age and sex groups by means of iif. of the 300 studied sera, only 4% had antibodies at titers greater than or equal to 1:16, a fact that shows the low prevalence of antibodies against this microorganism in the area. such titers were mainly found among subjects over 40 years (p less than 0.001).19892490479
[new advances in rheumatology].(1) molecular pharmacology which is a starting to reach the market place, what is expected to be the next big step in the biotechnology revolution: the creation of complex compounds that are custom-designed to meet human needs. the new technology known as protein engineering promises to take us one step further by modifying natural proteins or by creating new ones especially by using somatic gene transfer and germ gene transfer and its influence on progeny. by doing this we hope to control some ...19892491405
autoimmunity in lyme disease: molecular cloning of antigens recognized by antibodies in the cerebrospinal fluid.in inflammatory disease of the central nervous system (cns), oligoclonal bands of immunoglobulin with restricted heterogeneity can often be observed in cerebrospinal fluid (csf) samples. these antibodies can be directed against the disease inducing pathogen or might be autoreactive and involved in the process of brain inflammation and demyelination. we used a molecular biology approach to characterize these antibody responses in patients with lyme disease. this disorder is caused by infections w ...19892491615
another swedish family with complete properdin deficiency: association with fulminant meningococcal disease in one male family member.inherited deficiency of the complement component properdin is described in a swedish family without any previous history of meningococcal infections. the properdin-deficient index patient died from a fulminant infection caused by neisseria meningitidis serogroup y. family investigation revealed properdin deficiency in the patient's half-brother and in the maternal grandfather. the half-brother had a history of pneumococcal pneumonia and meningitis probably caused by borrelia burgdorferi. opsonic ...19892502833
