| 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 |
| natural history of sin nombre virus infection in deer mice in urban parks in oregon. | sin nombre virus (snv), one of at least 45 hantaviruses described worldwide, is hosted by the deer mouse, peromyscus maniculatus, a common species throughout most of north america. herein, we describe general life-history characteristics of deer mice and the ways in which these factors relate to the incidence of snv infections among populations of this host species in and around portland, oregon. in total, 3,175 deer mice were captured from october 2002 to september 2005. transmission of snv app ... | 2010 | 20688636 |
| 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 |
