Eurytrema procyonis in a raccoon (Procyon lotor) from New York state--a first report

The digenean, Eurytrema procyonis, found in the pancreatic ducts of the raccoon (Procyon lotor), is reported for the first time from a juvenile female raccoon captured in July 1987, in New York State (USA). The presence of greater than 183 trematodes in the pancreatic ducts was an incidental finding at necropsy to an interstitial pneumonia which had caused emaciation, and for which the animal was euthanized. The pancreas, with the exception of the major pancreatic duct, was histologically normal. The duct, containing the parasites, was dilated and contained a diffuse subepithelial inflammatory infiltrate consisting primarily of eosinophils. Epithelial hyperplasia was present in tubulo-alveolar glands, and goblet cells were prominent.
