Prevalence of Borrelia (Spirochaetaceae) Spirochetes in Texas Ticks

Abstract

Between 1990 and 1992, ticks from eight Texas parks were collected and analyzed to determine the prevalence of spirochete-infected ticks. Borrelia spirochetes were detected in 1.03% of 5,141 Amblyomma americanum (L.) adults examined, a species Texas residents often encounter. No spirochetes were observed in the other tick species tested.
