Abstract
An experimental fattening period was performed with 36 pigs in order to evaluate the safety and efficacy of a bivalent adjuvanted Serpulina hyodysenteriae bacterin. The pigs originated from three different farms and were split into six groups. Eighteen pigs were vaccinated twice, two weeks apart and the rest served as controls. One unvaccinated pig in each group was inoculated intragastrically with 4 x 10(8) active S. hyodysenteriae spirochaetes, B 78 strain. Weight evolution, clinical symptoms, shedding of S. hyodysenteriae and serum antibody titres were monitored for 12 weeks in all pigs. The severity of clinical symptoms and shedding of spirochaetes in faeces were significantly reduced in vaccinated pigs as compared to controls. Statistically significant differences in weight gain between vaccinates and controls were detected coinciding with the maximum shedding of S. hyodysenteriae in faeces. All vaccinated pigs seroconverted, as measured by indirect ELISA, and had a good anamnestic response after the second vaccine dose. The bacterin proved to be useful for both the reduction of clinical symptoms and the number of infected animals in a fattening unit. Adverse post-vaccinal reactions were not observed in any pig.

Abstract
The relative proportions of cells containing the various classes of immunoglobulins in the colonic mucosa were determined in eight patients with human intestinal spirochaetosis (HIS) and in eight controls. All specimens were taken from colonic resections performed because of adenocarcinoma. None of the cases with HIS showed an inflammatory reaction in the mucosa as judged subjectively by light microscopy. Cases with HIS had smaller proportions of IgD- and IgE-positive cells and a larger proportion of IgA cells as compared with the controls, whereas the proportions of IgG and IgM cells were similar in the two groups. Taking into account the large individual variations in the proportions of immunoglobulins in both groups, our findings must be interpreted with caution. However, our results do not support the previous demonstration of increased percentages of IgE-positive cells in patients with HIS.

Abstract
After oral challenge exposure with Serpulina hyodysenteriae-infected diced colon, fewer swine vaccinated with an experimental vaccine adjuvanted with mineral oil died (8 of 25 [32%]) than did nonvaccinated controls (6 of 15 [40%]), although the difference was not significant. However, onset and exacerbation of dysentery were accelerated in vaccinated swine because: 5 of the 8 dead vaccinated swine died before any of the nonvaccinates, which was significant (P < 0.01); vaccinated swine that died were observed to have more hemorrhage in the feces, colonic mucosa, and colonic lumen than did nonvaccinated swine; and the earlier diarrhea onset in vaccinates, the more days of hemorrhagic diarrhea (P < 0.05). Antibody titer in vaccinated swine immediately before challenge exposure that subsequently died was significantly (P < 0.05) higher than that in vaccinated swine that recovered. Of of the 30 swine vaccinated with the experimental vaccine, 20 had dispersed droplets of mineral oil at the site of vaccination in the neck muscles and 3 swine had purulent abscesses at the injection site. It was concluded that vaccination with the experimental vaccine for controlling swine dysentery was ineffective.

Abstract
The aetiology of Alzheimer's disease (AD), which affects a large proportion of the aged population is unknown and the treatment unresolved. The role of beta amyloid protein (beta A4), derived from a larger amyloid precursor protein (APP) in AD is the subject of intense research. Here I report observations that in 14 autopsy cases with histopathologically confirmed AD, spirochetes were found in blood and cerebrospinal fluid and, moreover, could be isolated from brain tissue. Thirteen age-matched control cases were without spirochetes. Reference strains of spirochetes and those isolated from brains of AD patients, showed positive immunoreaction with monoclonal antibody against the beta amyloid precursor protein. These observations suggest that spirochetes may be one of the causes of AD and that they may be the source of the beta amyloid deposited in the AD brain.

Abstract
The disease referred to as epizootic bovine abortion (EBA) was experimentally induced in bovine fetuses. Dark-field microscopy was used to detect congenital infection with an unclassified spirochaete-like organism. Some of the fetuses collected at abattoirs were also found to be naturally infected with a morphologically similar microorganism. Blood counts and organ weights were correlated with the presence of the microorganism. Lymphocyte blastogenesis increased, the result of in vivo stimulation among the infected fetuses. Phytomitogens (phytohaemagglutinin, concanavalin A and lipopolysaccharide) also stimulated greater responses in infected fetuses when compared to results in normal fetuses. Cellular cytotoxicity was examined by the single cell assay and results indicated that there were fewer cytotoxic lymphocytes among the diseased fetuses. The infected abattoir-collected specimens were obtained from clinically normal adult cattle, and the immunological changes in these fetuses were closely characterised with those of the EBA diseased fetuses. These naturally infected fetuses showed signs of a mild infectious disease.

Abstract
The pathogenetic and clinical importance of intestinal spirochaetes in man is still unresolved. In 12 patients mainly presenting with mild diarrhoea, light and electron microscopy demonstrated massive spirochaetal infestation of the colonic mucosa (spirochaetosis). There were several hitherto unreported features: spirochaetes adhered not only to the surface epithelium of the intestine but were also present within epithelial cells and subepithelial macrophages; many partially degranulated mast cells were noted within the epithelium; there was a marked increase of IgE plasma cells within the lamina propria. In control biopsies intraepithelial mast cells were absent and IgE cells occurred only sporadically. Penetration of the microorganisms into the intestinal mucosa may be responsible for this unusual immune response. Spirochaetes, symptoms and findings disappeared after antibiotic therapy. The authors therefore suggest that intestinal spirochaetosis can cause clinical symptoms in man, and that spirochaetes should not invariably be considered harmless commensals.

Abstract
Serum specimens from 163 persons with Lyme disease, tick-borne or louse-borne relapsing fever, yaws, syphilis, leptospirosis, or Rocky Mountain spotted fever were analyzed to assess the specificity of indirect fluorescent antibody (IFA) tests, an enzyme-linked immunosorbent assay (ELISA), and microscopic agglutination (MA) procedures. Strong cross-reactivity occurred when sera from individuals with Lyme disease, tick-borne relapsing fever, and louse-borne relapsing fever were tested against heterologous Borrelia antigens. Antibodies to Borrelia burgdorferi bound to Treponema pallidum in immunofluorescence tests for syphilis. Sera from subjects with syphilis cross-reacted in IFA tests and the ELISA for Lyme disease. Immunoglobulin antibodies to Borrelia or Treponema spirochetes, however, did not react with serovars of Leptospira interrogans in MA or IFA tests, and the prevalence of false-positive results in the reciprocal analyses was negligible.

Abstract
In Lyme's disease (LD) as well as in the European form of erythema chronicum migrans (ECM), the etiologic agents are spirochetes. As fas as we know by now, these microbes are closely related but not identical. Consequently, LD and ECM should be regarded as closely related but not as identical diseases. The sera of our 21 patients suffering from acrodermatitis chronica atrophicans (ACA) contained elevated antibody titers directed against the etiological agent found in ECM. These findings strongly suggest that ACA is also induced by spirochetes-possibly by the same microbes found in ECM.

Abstract
26 Swedish patients with erythema chronicum migrans (ECM) were studied regarding associated clinical symptoms and antibodies to Swedish Ixodes ricinus spirochete. 11/26 (42%) of the patients had associated symptoms, compared to more than 90% of 314 American patients with ECM, as described by Steere et al. Only 2/26 (8%) had multiple skin lesions, compared to 48% of the American patients. Elevated erythrocyte sedimentation rate and circulating immune complexes were demonstrated in 6/25 (24%) and 8/25 patients (32%), respectively, as against in 53% and 84%, respectively, of the American patients. The antibody response to Ixodes ricinus spirochete was measured by indirect immunofluorescence (IFA) and enzyme-linked immunosorbent assay (ELISA). Compared to the 95% percentile of controls, significantly high antibody titers were demonstrated in 3/25 (12%) by IFA, and 7/25 (28%) by ELISA. The ELISA antibody titers differed significantly (p less than 0.05) between ECM-patients and controls. The spirochetal antibody response in ECM was also compared with that in spirochete-associated disease of the central nervous system.

Abstract
Twenty consecutive patients visiting an otolaryngological department in Sweden with a facial palsy were investigated for serological signs of tick-borne spirochete infection. Four patients showed serological evidence of and had a medical history compatible with a tick-borne spirochetosis. Spinal fluid analyses were performed in 3 of these patients and showed elevated specific antispirochetal antibody titres and an increase in mononuclear cells. The importance of a correct diagnosis and of antibiotic therapy in patients with spirochete-induced facial palsy is emphasized.

Abstract
The clinical spectrum of this remarkable non-syphilitic spirochaetosis (spirochaeta infection) of the nervous system is described in light of 53 further cases with reference to our earlier description of 47 cases. As the etiological diagnosis is not possible in all cases the knowledge of clinical courses is especially important. Males are affected almost twice as often as women. The disease is especially prevalent in the sixth decade. Usually, the syndrome begins in the warm season with exquisite pain and other sensory irritations in combination with marked malaise. Initial signs during the winter as well as painless clinical courses were also noted. About one half of the patients remembered contact with arthropodes or a chronic migrating erythema. In most cases (95%), asymmetrical peripheral signs followed the painful stage. More than two thirds of the patients showed affection of cranial nerves, usually facial palsy. Twenty percent demonstrated paresis of the extremities alone, the combination of involvement of cranial nerves and extremities was noted in one third of the cases. The sensory signs were usually only mild. Occasionally, the neurological impairment was limited to isolated sensory impairment. In contrast to the closely related Lyme disease, central nervous affection as well as cardiac and arthritic involvement is rare: 34 percent demonstrated mild psychopathological impairment; in one case a Babinski-phenomenon was elicited. Knee joint pain and gonarthritis were found in one case each. Even though meningeal signs were usually absent, the CSF showed alterations suggestive of chronic lymphocytic meningitis in all cases. At the same time, local synthesis of all three immune globulins was documented, especially of IgM (85%).

Abstract
Antibodies to Swedish Ixodes ricinus spirochete were determined by an enzyme-linked immunosorbent assay (ELISA) in sera from 298 patients with postinfectious arthritis. Sera from healthy individuals, patients with acute infectious meningitis of proven etiology and patients with multiple sclerosis served as controls. With the upper limit of normal values set at the 95 percentile of controls, 18 of 298 (6%) arthritis patients had positive serum antibody titres. Titres above the 100 percentile of controls were found in 5 of 298 (2%) arthritis patients. Two of the arthritis patients had extremely high titres--higher than any earlier found in Swedish patients with spirochetal meningitis. The clinical manifestations and laboratory findings in the 5 patients with high spirochetal antibody titres are described. It is concluded that a spirochetal etiology should be considered in patients with reactive or postinfectious arthritis of unknown origin.

Abstract
In attempts to produce experimental Lyme disease, 33 rabbits were inoculated with Lyme spirochetes by tick feeding or from tick organ homogenates or cultures. Two rabbits developed erythema chronicum migrans at the site of inoculation, in one instance 2 days after injection of a tick organ homogenate and in the other instance, 17 days after feeding of infected Ixodes dammini ticks. Spirochetes were seen in skin biopsy specimens of the second lesion with Warthin-Starry and immunoperoxidase stains. Spirochetes were also recovered from blood cultures of two additional rabbits 2 weeks post-inoculation. These findings are characteristic of early Lyme disease in humans and give additional support for the spirochetal etiology of Lyme disease.

Abstract
An indirect immunofluorescence technique for the determination of antibodies against ixodid tick spirochetes is described. Differences in the reactivity between Ixodes ricinus spirochete and Ixodes dammini spirochete antigens were not observed. Cross-reacting antibodies against Treponema pallidum and Treponema phagedenis can be eliminated by quantitative absorption with T. phagedenis. Cross-reactions with leptospira were not observed by immunofluorescence. In the IgM test, false negative reactions caused by high-titered specific IgG antibodies or false positive reactions caused by rheumatoid factor occur. This can be avoided by testing the IgM fraction (19S-IgM-test) or using sera previously treated with anti-IgG serum. Significantly elevated antibody titers against ixodid tick spirochetes were observed in 45% of 44 cases with erythema migrans disease, in 72% of 29 cases of lymphocytic meningoradiculitis, in all of nine patients with acrodermatitis chronica atrophicans and in all of four investigated patients with lymphocytoma (lymphadenosis benigna cutis).

Abstract
The antibody response to the Ixodes dammini spirochete was determined in 41 serial serum samples from 12 patients with Lyme disease. By enzyme-linked immunosorbent assay (ELISA), 11 of the 12 patients had higher titers of specific IgM antibody (greater than 1:200) during early disease than did 40 control subjects. Specific IgM antibody titers, which correlated with total amounts of IgM antibody (P less than .001), sometimes remained elevated throughout the illness. During neuritis, nine of 10 patients had higher specific IgG antibody titers (greater than 1:200) than did controls, and when arthritis was present, all had such titers, which remained elevated after months of remission. In the ELISA, antibody responses determined by single or serial dilutions were similar, but the ELISA was more sensitive and specific than was immunofluorescence. Adsorption of sera with Borrelia hermsii generally resulted in a fourfold decrease in titers of cross-reactive antibodies, but the titers of sera from patients with Lyme disease were also reduced. Currently, the ELISA, without adsorption, is the best diagnostic test for Lyme disease.

Abstract
In the light of an observation of a patient with Lyme arthritis living near the Swiss-German border, the authors describe "Lyme or erythema migrans disease". The clinical findings include erythema chronicum migrans, meningoradiculitis and arthritis, and, occasionally, carditis. Also, it has recently become possible to describe this entity serologically, by detection of antibodies against the etiologically responsible spirochetes, which are usually transmitted by tick bites. This diagnostic procedure can also be expected to provide a better overview of the incidence of Lyme arthritis in our region.

Abstract
From ticks of the type Ixodes ricinus, 19 strains of a spirochete were isolated at three places of infection of erythema chronicum migrans disease. The spirochete was immunologically related to Borrelia duttoni, Treponema pallidum and Ixodes dammini spirochete, the causative organism of North American erythema chronicum migrans disease (Lyme disease). The isolated spirochete differed from the North American one in its reaction with monoclonal antibodies and possibly in its electronmicroscopic structure. A corresponding spirochete was isolated from the blood of a woman with erythema chronicum migrans. Of 39 patients with erythema chronicum migrans mostly treated with antibiotics 50% had increased IgG antibody titre (1:64 to 1:1024) against the isolated spirochete, while among 51 untreated patients with tick-transmitted meningopolyneuritis 90% had increased IgG antibody titres. Fourfold antibody titres increases or falls were found on 50 occasions. IgG antibody titres up to 1:64 were demonstrated also in CSF, in 22 instances with significant changes. Increased serum IgM antibody titres of 1:32 to 1:256 were observed in 20% and 68%, respectively, of patients. These findings suggest that the isolated spirochete is the causative agent of erythema chronicum migrans disease in Europe. Its antigen structure and arrangement is similar to that of the causative agent of Lyme disease.

Abstract
Ixodid tick-associated spirochetes have been implicated as the etiological agents of Lyme disease. We raised a murine monoclonal antibody (H5332) against a spirochete, strain B31, isolated from Ixodes dammini ticks. In indirect immunofluorescence assays and western blot analyses, H5332 reacted with whole cells or isolated components of not only strain B31 but also spirochetes isolated from Ixodes ricinus ticks, a field mouse, a raccoon, and patients with Lyme disease. In contrast, H5332 did not bind to representative borreliae, treponemes, and leptospires. Using indirect immunofluorescence assays and immune electron microscopy, we found the H5332 determinant to be diffusely distributed over the surface of prefixed spirochetes but to be aggregated in patches when the organisms were incubated with H5332 and a second ligand before fixation. Radioimmunoprecipitation and western blot studies revealed the H5332 determinant to be either on or tightly associated with an abundant outer membrane protein with an apparent subunit molecular weight of 31,000.

Abstract
Lyme disease is an inflammatory disorder of skin, joints, nervous system, and heart. The disease is associated with a preceding tick bite and is ameliorated by penicillin treatment. A spirochete (IDS) isolated from Ixodes dammini ticks has been implicated as the etiologic agent of Lyme disease. We examined the antibody responses of Lyme disease patients to IDS lysate components in order to further understand the pathogenesis of this disease. The components were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, transferred to nitrocellulose, reacted with patients' sera, and the bound IgG was detected with 125I-labeled protein A (western blot). We found that (a) Lyme disease patients had antibodies to IDS components (b) most patients studied had antibodies to two components with apparent subunit molecular weights of 41,000 and 60,000, and (c) the patients' antibody responses during illness and remission were specific, for the most part, for the IDS. In contrast to the findings with Lyme disease sera, sera from controls showed little reactivity with IDS components in either the western blots or a derivative solid-phase radioimmunoassay.

Abstract
Serums from 119 swine exposed to swine dysentery inoculum, and medicated with various drugs, were tested for antibodies to the large spirochete, using the indirect fluorescent antibody test, and were compared in tests with known positive serums from 18 nonmedicated swine which had recovered naturally. An inverse relationship existed between the efficacy of the drug and the serum antibody titer (highest dilution of the serum producing immunofluorescence of large spirochetes). The more efficacious drugs or doses resulted in lesser development of serum antibody. Diarrhea usually seemed necessary for the development of serum antibody. With the less efficacious drugs, there were more days of diarrhea. Some swine had diarrhea but did not develop an antibody titer, and a few swine had a titer but did not develop diarrhea. Swine which developed a titer were more immune against reexposure with infective inoculum. The medicaments, especially those given at higher concentrations, seemed to resolve the diarrhea or prevent the development of diarrhea, occurrences which were necessary for the development of immunity.
