We report a novel poxvirus infection characterized by proliferative epidermal lesions in wild northern pygmy mice (Baiomys taylori
) found at 2 localities in east central Texas, USA, and further characterize the virus through genetic analysis.
The Northern Pygmy Mouse (Baiomys taylori
) is a small grassland rodent that reaches its northern distributional limits in southwestern parts of the United States (Hall 1981; Eshelman & Cameron 1987).
However, it has been studied under laboratory conditions in Mastomys natalensis (Johnston and Oliff, 1954), Baiomys taylori
(Hudson, 1974), Peromyscus californicus (Gubernick, 1988), and Proechimys chrysaeolus (Sabogal-Guaqueta et al., 2013), among others.

yerbabuenae and rodents such as Reithrodontomys fulvescens and Baiomys taylori
(not collected on the coastal plain for this project but recorded near Huajicori and Acaponeta, Nayarit, about 50 km from the river valley) occur on both sides of the SMO, but eastern and western populations are usually considered as isolated by the mountain barrier.

We predicted that rodent species dependent on dense herbaceous foliage and litter for cover and/or diet would consequently decrease in abundance following cover reduction by fire, e.g., hispid cotton rat (Sigmodon hispidus) and northern pygmy mouse (Baiomys taylori
The pygmy mouse (Baiomys taylori
) is a small mouse from a Neotropical clade of mammals that seems to be actively expanding its geographic distribution.
We note that antibody against AMAV has been found in northern pygmy mice (Baiomys taylori
) captured in Texas and northern Mexico (14).
