Successful in vitro cultivation of Borrelia duttonii and its comparison with Borrelia recurrentis [PDF]

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 1999
Borrelia duttonii, the cause of East African tick-borne relapsing fever, has until now been refractory to growth in laboratory media. This spirochaete has only be propagated in mice or by tissue culture, restricting both yield and purity of cells available for research. The successful isolation of five clinical isolates of B.

Borrelia recurrentis Characterization and Comparison with Relapsing-Fever, Lyme-Associated, and Other Borrelia spp. [PDF]

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 1997
Borrelia recurrentis, the cause of louse-borne relapsing fever, has until recently been considered noncultivable, which has prevented characterization of this spirochete. We successfully cultivated 18 strains from patients with louse-borne relapsing fever and present the initial characterization of these isolates.

Infection with Borrelia recurrentis: Pathogenesis of Fever and Petechiae

Journal of Infectious Diseases, 1979
Patients infected with the spirochete Borrelia recurrentis were studied to determine the cause of fever and mechanism of petechia formation. The limulus test for endotoxin was applied to plasma. Spirochetes were concentrated from the blood by differential centrifugation and tested for endotoxin activity.

Relapsing fever spirochetes Borrelia recurrentis and B. duttonii acquire complement regulators C4b-binding protein and factor H.

open access: yesInfection and Immunity, 2006
Relapsing fever is a rapidly progressive and severe septic disease caused by certain Borrelia spirochetes. The disease is divided into two forms, i.e., epidemic relapsing fever, caused by Borrelia recurrentis and transmitted by lice, and the endemic form,

Dehydrogenase activity ofBorrelia recurrentis

Experientia, 1959
Es wurde gezeigt, dassBor. recurrentis unter ublichen Bedingungen nur eine schwache Fahigkeit besitzt, verschiedene Substrate zu dehydrogenieren. In Gegenwart von reduzierenden Agentien (wie SH-Verbindungen oder Ascorbinsaure) wird diese Aktivitat hingegen bedeutend verstarkt.

New England Journal of Medicine, 2016
After collapsing in Munich, a 16-year-old male Somalian refugee was brought to a local hospital with severe headache and abdominal pain. His vital signs were notable for a temperature of 41°C, a heart rate of 105 bpm, and blood pressure of 95/50 mm Hg.

ELECTRON MICROSCOPY OF BORRELIA MERIONESI AND BORRELIA RECURRENTIS

Acta Pathologica Microbiologica Scandinavica Section B Microbiology and Immunology, 1974
Borrelia merionesi and Borrelia recurrentis were studied in the electron microscope by means of negative staining and sectioning techniques. The cells of the two species had similar morphology. The cells were regularly waved and had pointed ends. Each organism had two bundles of flagella, one bundle originating from each end of the cell and each ...

Functional and structural identification of a new lectin activity of Borrelia recurrentis spirochetes

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993
1. Haemagglutinating activity (HA) was found and characterized in lysate of the spirochete Borrelia recurrentis. 2. The highest HA was observed using native rabbit red blood cells (RBC), especially oxidized rabbit RBC. 3. In a haemagglutination inhibition test the HA showed an affinity with monosaccharides D-glucosamine, D-galactosamine and N-acetyl-D ...
