Caption:
This photograph depicts the shaved anterior thoracoabdominal region of a rock squirrel, Spermophilus variegatus, formerly known as Citellus variegatus, which was infected with the plague bacterium, Yersinia pestis. See PHIL 6270, and 14296, and for another view of the exterior of this squirrel. Note the petechial rash, which is similar in appearance to those found on humans also afflicted with Yersinia pestis. A petechial rash refers to small, pinpoint, flat lesions of the skin and mucous membranes that are associated with hemorrhages beneath the skin surface. There was also a round, subcutaneous hemorrhage that had developed in the anterior abdominal wall, as well.
