Physical and Genetic Map of the Borrelia miyamotoi Chromosome : Comparison with That of Borrelia turicatae, an Etiological Agent of Tick-Borne Relapsing Fever [PDF]

, 1997
P(論文)I report the construction of physical maps of chromosomes for Borrelia miyamotoi HT31 and Borrelia turicatae (relapsing fever agent) by pulsed field gel electrophoresis of DNA fragments generated by digestion of chromosomal DNA with rare-cutting ...

Real-time monitoring of disease progression in rhesus macaques infected with Borrelia turicatae by tick bite. [PDF]

J Infect Dis, 2014
The hallmark of disease caused by tick- and louse-borne relapsing fever due to Borrelia infection is cyclic febrile episodes, which in humans results in severe malaise and may lead to death. To evaluate the pathogenesis of relapsing fever due to spirochetes in an animal model closely related to humans, disease caused by Borrelia turicatae after tick ...

Extensive interplasmidic duplications change the virulence phenotype of the relapsing fever agent Borrelia turicatae [PDF]

Molecular Microbiology, 1999
The relapsing fever agent Borrelia turicatae has two antigenically distinct serotypes, A and B, which differ in their variable small proteins (Vsps) and in their degree of virulence and neurotropism in mice. Each Vsp gene (vspA or vspB) had an expression‐linked copy that was unique to the serotype expressing it.

Structure-function investigation of vsp serotypes of the spirochete Borrelia hermsii.

PLoS ONE, 2009
BackgroundRelapsing fever (RF) spirochetes are notable for multiphasic antigenic variation of polymorphic outer membrane lipoproteins, a phenomenon responsible for immune evasion. An additional role in tissue localization is suggested by the finding that

TICK-BORNE INFECTIOUS DISEASES WITH REFERENCE TO EGYPT [PDF]

Journal of the Egyptian Society of Parasitology, 2016
Ticks are hematophagous ectoparasites of man, domestic and street animals, and birds of health and economic hazard worldwide. They transmit many micro-organisms and protozoan infectious diseases and their toxins cause different signs and symptoms that ...

A serological assay to detect and differentiate rodent exposure to soft tick and hard tick relapsing fever infections in the United States [PDF]

, 2023
Human cases of relapsing fever (RF) in North America are caused primarily by Borrelia hermsii and Borrelia turicatae, which are spread by argasid (soft) ticks, and by Borrelia miyamotoi, which is transmitted by ixodid (hard) ticks. In some regions of the

Epidemiological Overview of Borreliosis in Humans, Animals, and Ticks in Morocco: A Systematic Review Within a One Health Perspective

Psyche: A Journal of Entomology, Volume 2026, Issue 1, 2026.
Background Currently, zoonotic diseases pose a threat to international public health, such as Borreliosis, which is considered an emerging vector‐borne zoonotic infectious disease, usually inoculated by ticks and caused by the spirochete Borrelia spp.

Development of a rapid and reliable surveillance method for Ornithodoros turicata americanus in gopher tortoise (Gopherus polyphemus) burrows in the southeastern United States

Medical and Veterinary Entomology, Volume 39, Issue 1, Page 122-133, March 2025.
We developed a rapid, effective technique for surveying for Ornithodoros turicata, a vector of African swine fever virus using gopher tortoise burrows. When working under a time constraint during tick collection, vacuuming substrate from the top meter of the burrow followed by sifting for soft ticks outperformed CO2 traps.

Crystal Structure of Neurotropism-Associated Variable Surface Protein 1 (Vsp1) of Borrelia turicatae [PDF]

Journal of Bacteriology, 2006
ABSTRACT Vsp surface lipoproteins are serotype-defining antigens of relapsing fever spirochetes that undergo multiphasic antigenic variation to allow bacterial persistence in spite of an immune response. Two isogenic serotypes of Borrelia turicatae strain Oz1 differ in their Vsp sequences and in disease ...
