Transmission dynamics of Borrelia turicatae from the arthropod vector. [PDF]

PLoS Neglected Tropical Diseases, 2014
BackgroundWith the global distribution, morbidity, and mortality associated with tick and louse-borne relapsing fever spirochetes, it is important to understand the dynamics of vector colonization by the bacteria and transmission to the host.

Serological evidence of Borrelia turicatae in Raccoons (Procyon lotor) from an endemic focus of tick-borne relapsing fever in Mexico. [PDF]

PLoS Neglected Tropical Diseases
Tick-borne relapsing fever is a neglected and overlooked disease. In Mexico, numerous historical reports document the distribution of Ornithodoros turicata, the vector of Borrelia turicatae, as well as human cases of infection.

Autogenous reproduction by Ornithodoros turicata (Ixodida: Argasidae) females and vertical transmission of the tick-borne pathogen Borrelia turicatae (Spirochaetales: Borreliaceae). [PDF]

Appl Environ Microbiol, 2023
ABSTRACT Ornithodoros turicata is a vector of relapsing fever spirochetes in North America and transmits Borrelia turicatae to a variety of vertebrate hosts. The remarkably long lifespan of O.

Antibodies to Borrelia turicatae in Experimentally Infected Dogs Cross-React With Borrelia burgdorferi Serologic Assays. [PDF]

Journal of Clinical Microbiology, 2019
Tick-borne relapsing fever (TBRF) is caused by several Borrelia spp. (including Borrelia turicatae ), which are primarily transmitted by Ornithodoros ticks. Relapsing fever group species are found worldwide, except for Antarctica.

Transcriptional Profiling the 150 kb Linear Megaplasmid of Borrelia turicatae Suggests a Role in Vector Colonization and Initiating Mammalian Infection. [PDF]

PLoS ONE, 2016
Adaptation is key for survival as vector-borne pathogens transmit between the arthropod and vertebrate, and temperature change is an environmental signal inducing alterations in gene expression of tick-borne spirochetes.

Vector Competence of Geographical Populations of Ornithodoros turicata for the Tick-Borne Relapsing Fever Spirochete Borrelia turicatae. [PDF]

Applied and Environmental Microbiology, 2018
Several knowledge gaps exist in the vector competence of various geographical populations ofO. turicatathat transmitB. turicatae. A western population of this tick is distributed from California to Texas, and an eastern population exists in Florida. Utilizing western and eastern populations of the vector, we studied acquisition and transmission of twoB.

Aislamiento de Borrelia turicatae de Ornithodoros turicata colectada en México [PDF]

, 2023
RESUMEN Las espiroquetas causantes de la fiebre recurrente (FR) son patógenos del género Borrelia transmitidos por garrapatas blandas y duras. Esta enfermedad se considera como desatendida y emergente. Aunque la enfermedad se ha descrito y diagnosticado en México, al momento no se ha logrado el aislamiento de la bacteria causante de la misma.

Molecular Characterization of the Interaction of Borrelia parkeri and Borrelia turicatae With Human Complement Regulators. [PDF]

Infection and Immunity, 2010
ABSTRACTIn North America, tick-borne relapsing fever is caused by the speciesBorrelia hermsii,B. parkeri, andB. turicatae, which are transmitted to humans through the bite of the respective infected tick vectors. Here we describe the identification and functional characterization of a surface lipoprotein ofB.

Imaging of Borrelia turicatae Producing the Green Fluorescent Protein Reveals Persistent Colonization of the Ornithodoros turicata Midgut and Salivary Glands From Nymphal Acquisition Through Transmission. [PDF]

Applied and Environmental Microbiology, 2017
ABSTRACT Relapsing fever (RF) spirochetes colonize and are transmitted to mammals primarily by Ornithodoros ticks, and little is known regarding the pathogen's life cycle in the vector. To further understand vector colonization and transmission of RF spirochetes, Borrelia turicatae ...

Typing of Borrelia Relapsing Fever Group Strains [PDF]

Emerging Infectious Diseases, 2004
Partial sequencing of the 16S-23S rDNA intergenic spacer showed two to four genotypes each for Borrelia hermsii and B. turicatae, both relapsing fever agents transmitted by argasid ticks, and for B. miyamotoi and B. lonestari, transmitted by ixodid ticks.
