Characterization of the arthropod associated lipoprotein (Alp) in the tick-mammalian transmission cycle of Borrelia turicatae. [PDF]

Ticks Tick Borne Dis, 2022
Pathogenic species of Borrelia are etiological agents of tick-borne relapsing fever (TBRF). Most species of TBRF Borrelia are transmitted by argasid ticks, and persistent colonization of the salivary glands is vital for spirochete transmission. This is due to the fast-feeding dynamics of the vector.

Multifunctional interaction of CihC/FbpC orthologs of relapsing fever spirochetes with host-derived proteins involved in adhesion, fibrinolysis, and complement evasion [PDF]

Frontiers in Immunology
IntroductionRelapsing fever (RF) remains a neglected human disease that is caused by a number of diverse pathogenic Borrelia (B.) species. Characterized by high cell densities in human blood, relapsing fever spirochetes have developed plentiful ...

Colony formation in solid medium by the relapsing fever spirochetes Borrelia hermsii and Borrelia turicatae. [PDF]

Ticks Tick Borne Dis, 2018
Relapsing fever (RF) in North America is caused primarily by the spirochete Borrelia hermsii and is associated with the bite of its tick vector Ornithodoros hermsi. Although this spirochete was known long before the discovery of the Lyme disease (LD) spirochete, Borrelia burgdorferi, basic methods to facilitate the study of B.

Crystal Structure of Borrelia turicatae protein, BTA121, a differentially regulated  gene in the tick-mammalian transmission cycle of relapsing fever spirochetes. [PDF]

Sci Rep, 2017
Tick-borne relapsing fever (RF) borreliosis is a neglected disease that is often misdiagnosed. RF species circulating in the United States include Borrelia turicatae, which is transmitted by argasid ticks.

Archives of Razi Institute, 1967
Summary One strain of Borrelia turicatae and one of B. parkeri were studied. The organisms had chemical compositions similar to those of leptospirae and of Trypanosoma brucei . Three antigenic factors were isolated, of which two were proteins and one a protein or polypeptide complex. One antigen, designated B, was shared by B. turicatae and B.

Characterization of Immunological Responses to Borrelia Immunogenic Protein A (BipA), a Species-Specific Antigen for North American Tick-Borne Relapsing Fever

Microbiology Spectrum, 2022
Tick-borne relapsing fever (TBRF) is a neglected vector-borne bacterial disease distributed worldwide. Borrelia turicatae, Borrelia parkeri, and Borrelia hermsii are three argasid-borne TBRF species previously implicated in human disease in North America.

T-cell-independent elimination of Borrelia turicatae [PDF]

Infection and Immunity, 1984
Mice deficient or deprived of thymus-derived lymphocytes eliminated blood-borne Borrelia turicatae with efficiency comparable to that observed in normal littermates. When challenged with 10(5) borreliae, nude mice had mean (+/- standard deviation) primary spirochetemias lasting 3.1 +/- 0.2 days and mean (+/- standard deviation) peak bacterial counts of

Molecular characterization of the interaction of Borrelia parkeri and Borrelia turicatae with human complement regulators. [PDF]

Infect Immun, 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.
