The scientists dedicated four years to decoding the genetic makeup of the white-footed mouse Peromyscus leucopus
, which harbors the Lyme disease-causing bacteria.
In the United States, New York orthohantavirus (NYV) is carried by the white-footed mouse (Peromyscus leucopus
Other small scavengers that frequented the ARF included Virginia opossum (Didelphis virginiana), brown rat (Rattus norvegicus), and white-footed mouse (Peromyscus leucopus
Finally, only one rodent was captured of the species Sigmodon toltecus and one of the species Peromyscus leucopus
The white-footed mouse (Peromyscus leucopus
) is a forest habitat generalist that occurs in abundance within fragmented woodlots (forest patches) throughout the eastern United States (Nupp and Swihart, 1996; Wilder and Meikle, 2005a).
Systematic Studies of the White-footed Mouse (Peromyscus leucopus
One arm of their research has taken them to the lab, where they have modeled coinfection and transmission of Borrelia burgdorferi and Babesia microti from their reservoir host, the white-footed mouse (Peromyscus leucopus
), to the vector, the deer tick (Ixodes scapularis), which can transmit both diseases to humans.
This study tested the prediction that Peromyscus leucopus
scent collected in the lab and placed in cleaned (experimental) traps would attract conspecifics with similar or higher frequency than regular clean traps or dirty traps containing the residual scent of previously captured conspecifics.
The preferred hosts of the suspected species of Cuterebra are Peromyscus maniculatus and Peromyscus leucopus
. All the infected individuals caught had one or more bot flies in the inguinal area, near the genitals.

Vasopressin and aggression in cross-fostered California mice (Peromyscus californicus) and white-footed mice (Peromyscus leucopus
In this study, the taxonomic diversity of small mammals included four species of squirrels (Sciurus carolinensis, Sciurus niger, Glaucomys volans, and Tamias striatus), one species of shrew (Blarina carolinensis), and seven species of cheek rodents (Mus musculus, Sigmodon hispidus, Peromyscus leucopus
, P gossypinus, Ochrotomys nuttalli, Oryzomyz palustris, and Reithrodontomys humulis).
