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.

Prevalence, distribution, and phylogenetics of the tick-borne relapsing fever spirochete Borrelia turicatae in the soft tick Ornithodoros turicata americanus in Florida. [PDF]

PLoS Negl Trop Dis
In the southwestern United States, the occurrence and potential for disease spread of Tick-Borne Relapsing Fever (TBRF) has been studied. In Florida, Borrelia pathogens that cause TBRF have only been found in two domestic dogs ( Canis lupus familiaris ),

مطالعات بورلیا، 2- برخی از خواص ایمنی زایی، بیوشیمیایی و فیزیکی ترکیبات آنتی ژنی Borrelia turicatae [PDF]

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.

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

Relapsing Fever Infection Manifesting as Aseptic Meningitis, Texas, USA

Emerging Infectious Diseases, 2021
Tickborne relapsing fever spirochetes are an overlooked cause of disease around the globe. We report a case of tickborne relapsing fever in a patient in Texas, USA, who had a single febrile episode and gastrointestinal and neurologic symptoms. Immunoblot

Immunological Responses to the Relapsing Fever Spirochete Borrelia turicatae in Infected Rhesus Macaques: Implications for Pathogenesis and Diagnosis. [PDF]

Infect Immun, 2019
The global public health impact of relapsing fever (RF) spirochetosis is significant, as the pathogens exist on five of seven continents. The hallmark sign of infection is episodic fever and the greatest threat is to the unborn. With the goal of better understanding the specificity of B cell responses and the role of immune responses in pathogenicity ...

Immunologic and genetic analyses of VmpA of a neurotropic strain of Borrelia turicatae [PDF]

Infection and Immunity, 1997
In mice infected with serotype A but not serotype B of the relapsing fever spirochete Borrelia turicatae, early invasion of the brain occurs. Serotypes A and B are further distinguished by the abundant surface protein they produce: VmpA and VmpB, respectively.

Human Exposure to Spirochete-Infected <i>Ornithodoros turicata</i> in a Residential Setting in the Austin, Texas Metropolitan Area. [PDF]

Open Forum Infect Dis
A central Texas resident found an engorged Ornithodoros turicata tick attached to their ankle while at home. The tick tested positive for Borrelia turicatae, an agent for soft tick-borne relapsing fever.
