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.

Does RecA have a role in Borrelia recurrentis? [PDF]

open access: yesClinical Microbiology and Infection, 2011
Genomic sequencing of two relapsing fever spirochaetes showed truncation of recA in Borrelia recurrentis, but not in Borrelia duttonii. RecA has an important role among bacteria; we investigated whether this characteristic was representative of B. recurrentis, or an artefact following in vitro cultivation.

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

open access: yesInternational Journal of Systematic Bacteriology, 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.

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.

Borrelia recurrentisInfection

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.
