| isolation of borrelia burgdorferi from neotoma fuscipes, peromyscus maniculatus, peromyscus boylii, and ixodes pacificus in oregon. | the number of lyme disease cases in oregon has increased in recent years despite the fact that the pathogen, borrelia burgdorferi, has never been isolated in the state. rodent and tick surveys were undertaken in 1997 to isolate and characterize strains of b. burgdorferi from oregon and to identify potential reservoirs and vectors of lyme disease. borrelia burgdorferi was isolated from neotoma fuscipes, peromyscus maniculatus, p. boylii, and ixodes pacificus. both n. fuscipes and p. maniculatus w ... | 1999 | 10466976 |
| effects of an invasive forest pathogen on abundance of ticks and their vertebrate hosts in a california lyme disease focus. | invasive species, including pathogens, can have important effects on local ecosystems, including indirect consequences on native species. this study focuses on the effects of an invasive plant pathogen on a vertebrate community and ixodes pacificus, the vector of the lyme disease pathogen (borrelia burgdorferi) in california. phytophthora ramorum, the causative agent of sudden oak death, is a non-native pathogen killing trees in california and oregon. we conducted a multi-year study using a grad ... | 2010 | 20941513 |
| avian hosts of ixodes pacificus (acari: ixodidae) and the detection of borrelia burgdorferi in larvae feeding on the oregon junco. | larval and nymphal western blacklegged tick, ixodes pacificus cooley & kohls (acari: ixodidae), were collected from birds, rodents, and lizards at quail ridge reserve located in napa county in northwestern california. species from three vertebrate classes were sampled simultaneously from two transects during two consecutive spring seasons. feeding larval and nymphal ticks were removed and preserved for counting, examination and testing for the presence of borrelia burgdorferi johnson, schmid, hy ... | 2011 | 21845945 |
