Ja. Rawlings et Gj. Teltow, PREVALENCE OF BORRELIA (SPIROCHAETACEAE) SPIROCHETES IN TEXAS TICKS, Journal of medical entomology, 31(2), 1994, pp. 297-301
Between 1990 and 1992, ticks from eight Texas parks were collected and
analyzed to determine the prevalence of spirochete-infected ticks. Bo
rrelia spirochetes were detected in 1.03% of 5,141 Amblyomma americanu
m (L.) adults examined, a species Texas residents often encounter. No
spirochetes were observed in the other tick species tested.
