Small rodents, including white-footed mice
(Peromyscus leucopus) and chipmunks (Tamias striatus) live-trapped at the same locations were bled following procedures approved by the institutional animal care and use committees of each institution.
Long-term population trends in white-footed mice
and the impact of supplemental flood and shelter.
Numerous studies have shown that a series of hantaviruses similar to SN virus are maintained in natural reservoirs composed of Sigmodontine rodents, including deer mice (Peromyscus maniculatus), white-footed mice
leucopus as a substrate for travel, and white-footed mice
in eastern woodlands tend to avoid areas with little or no woody ground litter (Planz and Kirkland, 1992).
Although repeated nymphal infestations may protect inbred laboratory mice from tick-borne spirochetes (22), natural reservoir hosts, such as white-footed mice
and American robins, remain susceptible to such spirochetes, regardless of prior exposure to ticks (1, 23).
One potential explanation is that in small patches with greater edge-to-interior ratios, white-footed mice
are able to utilize surrounding matrix resources to supplement within-patch populations (Nupp and Swihart, 1998; Anderson et al.
The team identified the evolutionary impacts on species on a wide variety of species ranging from the common blackbird in Europe to white clovers and white-footed mice
in North America.
Cases of Hantavirus Pulmonary Syndrome (HPS), a life-threatening infection that can be transmitted by deer mice, white-footed mice
, cotton rats and rice rats have been confirmed in the majority of our 50 states.
As larvae and nymphs, the ticks most often obtain these meals from white-footed mice
or other small rodents, although they occasionally latch onto other creatures--a raccoon, a bird, or an unfortunate human.
are a popular first host, as well as a very common carrier of diseases and parasites that can infect humans.
Agonistic spacing behavior in white-footed mice
, Peromyscus leucopus.
Distinctive Bb genes have been identified in museum collections of ticks from the 1940s and of white-footed mice
from the turn of the twentieth century," says science writer Sharon Levy.
