Parvovirus enteritis in a raccoon (Procyon lotor)

Clinical History: Two raccoons died in a pre-release rehabilitation pen in an interval of 1.5 weeks after appearing healthy. The second raccoon, a juvenile female, was submitted for postmortem examination. Necropsy Findings: In the small intestine, the subserosa is markedly hyperemic/congested (Fig. 1) with abundant watery, semi-translucid content and large amounts of tan-white mucus. The intestinal wall is thickened, and the mucosa is smooth and overlaid by thick mucus (Fig. 2). The large intestine contains moderate amounts of tan-yellow, mucoid digesta. Mesenteric lymph nodes are enlarged, the parenchyma is red and mildly protrudes on cut section.
