The genus Peromyscus contains species commonly referred to as deer mice. This is a genus of New World mouse only distantly related to the common house mouse, Mus musculus. The most common species of deer mouse in the continental United States are two closely related species, P. maniculatus, and P. leucopus. In the USA, Peromyscus is the most populous mammalian genus overall, and has become notorious in the western United States as a carrier of the hantavirus.[1][2] The word Peromyscus comes from the Greek for "booted mouse". [3] There is a different mammal by the name of "Mouse Deer," a relatively primitive ungulate of minuscule size.
[edit] DiseaseThe deer mouse came to the attention of the public when it was discovered to be the primary reservoir species for hantavirus.[1][4][5] A recent study in British Columbia, of 218 Deer mice showed that 30% (66) were seropositive for B. burgdorferi[6]. Ehrlichiosis, babesiosis, and bubonic plague are also carried by the deer mouse.[7] [edit] As a Laboratory AnimalWhile wild populations are sometimes studied, Peromyscus is also easy to breed and keep in captivity. For certain studies, it is also favoured over the common laboratory mouse (Mus domesticus) and the laboratory rat (Rattus norvegicus) . Apart from their importance in studying infectious diseases, Peromyscus are useful for studying phylogeography, speciation, chromosomes, genetics, ecology, population genetics, and evolution in general. They are also useful for researching repetitive movement disorders and aging research.[8][9][10][11] The Peromyscus Genetic Stock Center at the University of South Carolina was established in 1985 by Dr. Wallace Dawson to provide peromyscine species for research and educational use. The center maintains lines of several species (including Peromyscus californicus, Peromyscus maniculatus, Peromyscus melanophrys, Peromyscus eremicus and Peromyscus aztecus). A variety of mutations affecting behavior, biochemisty and coat colour are carried in these lines. [edit] Species
