Resumo
Macracanthorhynchus hirudinaceus infection which currently does not occur in modern swine production systems, mainly due to the raising characteristics, is considered a zoonosis. The purpose of this paper is to report the occurrence and the anatomopathological diagnosis of an outbreak of Macracanthorhynchus hirudinaceus infection in a commercial farm of white-lipped peccaries. At the farm, located on the outskirts of the city of Goiânia in the State of Goiás, and registered in the Instituto Brasileiro do Meio Ambiente e Recursos Naturais Renováveis , there were 150 animals of different ages, living in an area of 4.6 hectares, surrounded with wire screen fence and with a special paddock used for management. Besides foraging, the animals were fed with corn and cassava. In the stock, a mortality of 15 animals, less than one year old, was registered. Post-mortem examination was carried out on five of them, and samples were sent for microscopic and parasitological examination. Intense deposition of fibrin on abdominal organs, presence of reddish liquid in the abdominal cavity, large hemorrhagic area and necrosis of the epiploon were found in the post-mortem examination. In the small intestine wall there were many reddish nodules with flattened body parasites inside. These parasites had their proboscides attached to the intestinal mucosa. A granulomatous inflammatory infiltrate with moderate fibroplasia associated to the presence of eggs, larvae and proboscis of the adult parasite were found in the histopathological examination. During the parasitological examination the parasite was identified as Macracanthorhynchus hirudinaceus, confirming the outbreak.
