Tick-Borne Relapsing Fever Spirochetes in the Americas
Relapsing fever spirochetes are tick- and louse-borne pathogens that primarily afflict those in impoverished countries. Historically the pathogens have had a significant impact on public health, yet…

TLDR
Future efforts using field and laboratory surveys are needed to determine pathogenesis, vector competence and distribution in animals, their impact on animal health and productivity as well as to prevent further spill to the human population.
Tick borne relapsing fever - a systematic review and analysis of the literature.
TLDR
The most suggestive symptom in TBRF is the eponymous relapsing fever (present in 100% of the cases), and microscopy remains the diagnostic gold standard in most clinical settings.
Transovarial Transmission of Borrelia hermsii by Its Tick Vector and Reservoir Host Ornithodoros hermsi
TLDR
The perpetuation of B. hermsii for many years by infected ticks only (without acquisition of spirochetes from vertebrate hosts) demonstrates the reservoir competence of O. hermi, which produced the variable tick protein in eggs and unfed larvae infected by transovarial transmission.
Host associations and genomic diversity of Borrelia hermsii in an endemic focus of tick-borne relapsing fever in western North America
TLDR
Pine squirrels are the primary hosts for the maintenance of B. hermsii on the islands in Flathead Lake, however serological evidence showed that numerous additional species are also involved on the mainland and further studies will help define their role as hosts in this and other endemic foci.
Vaccination with the variable tick protein of the relapsing fever spirochete Borrelia hermsii protects mice from infection by tick-bite
TLDR
It is demonstrated that by having knowledge of the phenotypic changes made by B. hermsii as the spirochetes are acquired by ticks from infected mammals, an effective vaccine was developed that protected mice when challenged with infected ticks.
Transgenic functional complementation with a transmission -associated protein restores spirochete infectivity by tick bite.
Prevalence of Risk and Protective Factors for Tick Exposure and Tick-Borne Disease Among Residents of Indiana
TLDR
In Indiana, the area around people's residences may constitute an important source of tick exposure for humans and being exposed to ticks is most prevalent in those living in rural areas of Indiana.
Ticks and Tick-Borne Diseases of Colorado, Including New State Records for Argas radiatus (Ixodida: Argasidae) and Ixodes brunneus (Ixodida: Ixodidae)
TLDR
Tick-host associations, geographical distributions, and medical/veterinary importance are included and it is confirmed that C. concanensis and H. chordeilis have distributions that include CO.

Tickborne Relapsing Fever
In North America, tickborne relapsing fever (TBRF) is most commonly caused by Borrelia hermsii spirochetes that are transmitted from rodent reservoirs
Tick-borne Relapsing Fever and Borrelia hermsii, Los Angeles County, California, USA
TLDR
A patient presumably acquired this illness after exposure to ticks in mountains near Los Angeles following exposure to tick-borne diseases in the region.
Tick-borne Relapsing Fever Caused by Borrelia hermsii, Montana
TLDR
Borrelia hermsii was isolated from the blood of two patients, and Ornithodoros hermsi ticks were collected from the cabin, the first demonstration of this bacterium and tick in Montana.
Diversity and Distribution of Borrelia hermsii
Multilocus sequence analysis and laboratory experiments suggest that birds may play a role in maintaining and dispersing this pathogen.
POLYMERASE CHAIN REACTION OF TICK-BORNE RELAPSING FEVER CAUSED BY BORRELIA HERMSII
TLDR
The polymerase chain reaction is proposed as a possible alternative for currently used tests for the diagnosis of tick-borne relapsing fever and revealed Borrelia hermsii.

TLDR
Observations on the growth of Lyme disease spirochetes under different in vitro conditions may yield important clues to both the metabolic characteristics of these newly discovered organisms and the pathogenesis of Lyme Disease.

THE TRANSMISSION OF ROCKY MOUNTAIN SPOTTED FEVER BY THE BITE OF THE WOOD-TICK (DERMACENTOR OCCIDENTALIS).
TLDR
It is apparent that a means had been provided by which to test the theory of transmission by the wood-tick, a theory which was primarily advanced by Wilson and Chowning, and the study of the tick as an intermediate host for the parasite was taken up.
Serologic evidence for Borrelia hermsii infection in rodents on federally owned recreational areas in California.
TLDR
The serological studies described here are effective in implicating the primary vertebrate hosts involved in the maintenance of the ticks and spirochetes in regions endemic for TBRF.
