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.

Interaction of a neurotropic strain of Borrelia turicatae with the cerebral microcirculation system. [PDF]

Infect Immun, 2006
ABSTRACTRelapsing fever (RF) is a spirochetal infection characterized by relapses of a febrile illness and spirochetemia due to the sequential appearance and disappearance of isogenic serotypes in the blood. The only difference between isogenic serotypes is the variable major outer membrane lipoprotein.

Molecular and Immunological Analyses of the Borrelia turicatae Bdr Protein Family [PDF]

Infection and Immunity, 2000
ABSTRACT Here, we describe the molecular and immunological characterization of the bdr gene family of Borrelia turicatae , a relapsing-fever spirochete. Nine bdr alleles belonging to two different subfamilies were sequenced and localized to linear plasmids ...

Borrelia recurrentis employs a novel multifunctional surface protein with anti-complement, anti-opsonic and invasive potential to escape innate immunity [PDF]

, 2009
Borrelia recurrentis, the etiologic agent of louse-borne relapsing fever in humans, has evolved strategies, including antigenic variation, to evade immune defence, thereby causing severe diseases with high mortality rates.
