Case Report: A Retrospective Serological Analysis Indicating Human Exposure to Tick-Borne Relapsing Fever Spirochetes in Texas.

This article presents a case report of a Caucasian male from Texas who became ill with symptoms including fever, chills, uveitis, headache, and weakness. The patient had a history of outdoor activity and numerous insect bites, but the specific arthropods responsible were not found. After antibiotic treatment, a retrospective evaluation led to suspicion of tick-borne relapsing fever borreliosis. Serological testing using two diagnostic antigens indicated exposure to relapsing fever spirochetes. The article highlights the challenges of diagnosing and studying tick-borne relapsing fever borreliosis and identifies at-risk populations. [Extracted from the article]
