Je. Keirans et al., IXODES (IXODES) JELLISONI AND IXODES (IXODES) NEOTOMAE (ACARI, IXODIDAE) - DESCRIPTIONS OF THE IMMATURE STAGES FROM CALIFORNIA, Journal of medical entomology, 33(3), 1996, pp. 319-327
Nymphal and larval stages of Ixodes (Ixodes) jellisoni Cooley & Kohls
and I. (I.) neotomae Cooley are described for the first time. These 2
tick species occur only in the western United States, predominately in
California. The primary host for I. jellisoni is the California kanga
roo rat, Dipodomys californicus (Merriam); that for I, neotomae is the
dusky-footed woodrat, Neotoma fuscipes Baird. The etiologic agent of
Lyme disease Borrelia burgdorferi Johnson, Schmidt, Hyde, Steigerwalt
& Brenner has recently been isolated from both tick species, and I. ne
otomae was proven a competent enzootic vector of the Lyme disease spir
ochete.
