| survey for ixodes spp. and borrelia burgdorferi in southeastern wisconsin and northeastern illinois. | forested areas adjacent to milwaukee, wis., and chicago, ill., were investigated for rodents and ticks infected with borrelia burgdorferi, the causative agent of lyme disease. white-footed mice (peromyscus leucopus or peromyscus maniculatus), meadow voles (microtus pennsylvanicus), and eastern chipmunks (tamias striatus) were captured; and specimens from these animals were cultured for b. burgdorferi to define whether the midwestern lyme disease area currently encompasses these large metropolita ... | 1991 | 2007650 |
| role of the eastern chipmunk (tamias striatus) in the epizootiology of lyme borreliosis in northwestern illinois, usa. | the role of the eastern chipmunk (tamias striatus) in the epizootiology of lyme borreliosis was evaluated in castle rock state park, illinois (usa), an enzootic region, from june to august 1993. prevalence, intensity, and molting rate of immature ixodes scapularis were determined for chipmunks, white footed mice (peromyscus leucopus), and raccoons (procyon lotor). chipmunks were the primary host for i. scapularis nymphs and an important secondary host for i. scapularis larvae. based upon ear pun ... | 1997 | 9027689 |
| comparative phylogeography of eastern chipmunks and white-footed mice in relation to the individualistic nature of species. | palaeoecological studies have demonstrated that ecological communities as a whole did not remain stable throughout the climatic fluctuations of the quaternary. the result is that long-term associations of species cannot be inferred by contemporary associations in ecological communities. therefore, the evolutionary significance of any contemporary ecological interactions among species and of the biotic community within which species have evolved also cannot be assumed from contemporary conditions ... | 2006 | 17054499 |
| role of the eastern chipmunk as a host for immature ixodes dammini (acari: ixodidae) in northwestern illinois. | infestation of the eastern chipmunk, tamias striatus l., by immature ixodes dammini spielman, clifford, piesman and corwin was studied in castle rock state park in northwestern illinois during june-october 1991. mean larval density peaked in august, while nymphal density declined steadily through the study period. prevalence of tick infestation was high throughout the trapping period. tick distribution on chipmunks was aggregated in most of the sampling periods. levels of i. dammini infestation ... | 1993 | 8433349 |
