Attempts to infect juvenile and adult western fence lizards () with the Lyme borreliosis spirochete () were largely unsuccessful. Spirochetes could not be isolated from the blood and various tissues of 14 lizards 21–32 days after they had been inoculated ip (n = 8) or sc (n = 6) with 10 or 10 representing 3 tick isolates, although 1 lizard apparently developed a transitory spirochetemia lasting 2 days. Similarly, spirochetes could not be detected in the blood or tissues of 5 lizards fed upon by 2->8 infected larvae or nymphs of the western black-legged tick (). Sixty-five blood samples from 59 lizards in an endemic area and various tissues from 20 of the same lizards were also assayed for with negative results. The implications of these findings for the maintenance of this spirochete in natural foci are discussed.
