| spirochetes in mammals and ticks (acari: ixodidae) from a focus of lyme borreliosis in california. | in northern california, antibodies to borrelia burgdorferi were detected in 58 of 73 (79%), and spirochetemias in one of 26 (4%) black-tailed jackrabbits (lepus californicus californicus), by indirect and direct immunofluorescence, respectively. five species of ticks (dermacentor occidentalis, d. parumapertus, ixodes neotomae, i. pacificus, and haemaphysalis leporispalustris) were collected from rabbits. two of these species of ticks were found to contain spirochetes; two of 10 (20%) i. neotomae ... | 1988 | 3280837 |
| identification of an isolate of rickettsia canada from california. | a strain of rickettsia canada was recovered in 1980 an adult rabbit tick, haemaphysalis leporispalustris, taken from a black-tailed jack rabbit, lepus californicus, in mendocino county, california. in all examined biologic characteristics, this isolate, ca410, is indistinguishable from the prototype, strain 2678, isolated in ontario, canada, in 1963. these similarities include serologic and immunologic reactivity in laboratory mice and guinea pigs, cultural characteristics in vero cells, chick e ... | 1982 | 6756179 |
| risk of human exposure to vector ticks (acari: ixodidae) in a heavily used recreational area in northern california. | the risk of humans encountering vector ticks along hiking trails or in picnic grounds in a lyme disease-endemic area was evaluated in a multipurpose recreational area (tilden regional park) in the populous san francisco bay region of california. four hillside hiking trails (two high-use, two low-use) were sampled by dragging and walking through low vegetation biweekly for one year; four heavily used picnic areas were sampled concurrently by dragging. adults of three human-biting ticks were enume ... | 1996 | 8780455 |
| the roles of birds, lizards, and rodents as hosts for the western black-legged tick ixodes pacificus. | we compared the infestation by ixodid ticks of lizards, rodents, and birds collected simultaneously within areas representing common habitat types in mendocino county, ca. lizards were infested only by ixodes pacificus cooley and kohls, birds by i. pacificus and haemaphysalis leporispalustris (packard), and rodents by i. pacificus, i. spinipalpis hadwen and nuttall, i. woodi bishopp, dermacentor occidentalis marx, and d. variabilis (say). infestation by i. pacificus larvae and nymphs of lizards ... | 2004 | 15709249 |
| wild turkey (meleagris gallopavo) as a host of ixodid ticks, lice, and lyme disease spirochetes (borrelia burgdorferi sensu lato) in california state parks. | rio grande wild turkeys (meleagris gallopavo intermedia) were evaluated as potential hosts of ixodid ticks, lice, and lyme disease spirochetes (borrelia burgdorferi sensu lato [s.l.]) in three state parks in sonoma county, california, usa, during 2003 and 2004. in total, 113 birds were collected, 50 (44.2%) of which were found to be infested by 361 ixodid ticks representing three species: the western black-legged tick (ixodes pacificus, n=248), the rabbit tick (haemaphysalis leporispalustris, n= ... | 2006 | 17255442 |
| birds and their ticks in northwestern california: minimal contribution to borrelia burgdorferi enzootiology. | birds and their attendant ticks were surveyed for infection with the lyme disease spirochete borrelia burgdorferi, in chaparral and woodland-grass habitats in northwestern california from march to july, 1998 to 1999. in total, 234 birds were captured and recaptured (15%); nearly 2.5 times more birds were captured in chaparral than in woodland-grass. overall, 34 species representing 15 families were collected during this study; of these, 24 species were caught in chaparral, 19 in woodland-grass, ... | 2001 | 11534638 |
