Background: Canine parvovirosis, caused by canine parvovirus type 2 (CPV-2), emerged in the 1970s as an important disease affecting dogs, causing severe hemorrhagic gastroenteritis and death. It can occur in any breed, gender, and age; however, puppies of 4 to 12 weeks of age are most commonly afflicted. In 2000 a new variant of the virus, called CPV- 2c, was discovered, and has been related to hemorrhagic gastroenteritis in dogs with up to 2 years of age, although some cases have been described in older animals with a full vaccination history. This paper reports a case of enteritis by canine parvovirus type 2c (CPV-2c) in a 5-year-old dog. Case: At necropsy a pallid oral and conjunctival mucosae were observed. The small intestine showed a very reddish and wrinkled serosa, the wall was thickened, the mucosae was diffusely wrinkled and yellowed with evidenced Peyer plaques and there was no content in the final portion of the intestine. The mesenteric lymph nodes were enlarged and reddish. Multiple suffusions on the serosa of the stomach, and petechiae and subepicardial suffusions in the heart were observed. The histological findings were, collapse of the lamina propria of the small intestine, and fusion of the villi, necrosis of enterocytes, atrophy and the disappearance of crypts, with dilation of remaining crypts showing large rounded nuclei with one or two evident nucleoli...(AU)
