wood rats and kangaroo rats: potential reservoirs of the lyme disease spirochete in california.	the etiologic agent of lyme disease, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, was isolated repeatedly from dusky-footed wood rats, neotoma fuscipes baird, and california kangaroo rats, dipodomys californicus merriam, in northern california. all animals were collected in a region endemic for lyme disease but for which the natural reservoir of b. burgdorferi was unknown. similar attempts to isolate spirochetes from lizards, other species of rodents, jack rabbits, and deer ...	1991	1875357
lyme disease in california: a novel enzootic transmission cycle of borrelia burgdorferi.	knowledge of zoonotic transmission cycles is essential for the development of effective strategies for disease prevention. the enzootiology of lyme disease in california differs fundamentally from that reported from the eastern united states. woodrats, not mice, serve as reservoir hosts, and ixodes neotomae, a nonhuman-biting tick, maintains the agent of lyme disease, borrelia burgdorferi, in enzootic cycles. the western black-legged tick, ixodes pacificus, is the primary vector to humans, but i ...	1992	1604318
the western fence lizard sceloporus occidentalis: evidence of field exposure to borrelia burgdorferi in relation to infestation by ixodes pacificus (acari: ixodidae).	the role of the western fence lizard sceloporus occidentalis in the enzootiology of the lyme disease spirochete borrelia burgdorferi was evaluated in the hopland and ukiah areas of mendocino county, california. in 1989, half of 74 lizards collected monthly from april to october at hopland were infested by the immature western black-legged tick ixodes pacificus at a mean intensity of 6.0 ticks per lizard. the prevalence of infestation of lizards by immature i. pacificus (36 of 73) at ukiah was si ...	1992	1524146
occurrence of ixodes pacificus (parasitiformes: ixodidae) in arizona.	adults and immatures of ixodes pacificus cooley & kohls were collected by flagging vegetation and from lizards during a 3-mo period in the hualapai mountain park, mohave county, az, in 1991. collections were made at altitudes > or = 2,134 m. two of 48 gut-salivary gland extracts of adult ticks were positive by ifa using a monoclonal antibody (h5332) specific to borrelia burgdorferi. these are the first records of i. pacificus and of spirochetes tentatively identified as b. burgdorferi in arizona ...	1992	1460624
