Diarreia epidêmica suína (ped), enfermidade exótica no brasil mas emergente nas américas.

Recent outbreaks of Porcine Epidemic Diarrhea (PED) has been described in several countries, mainly in China and the United States, and it has causing significative economic impact to the swine industry worldwide. As the virus spread also in South America, affecting Peru, Colombia and Ecuador, knowledge about the disease is extremely important to maintain the free status of the disease in Brazil. PED is caused by a virus from Coronaviridae family, and is characterized by profuse liquid diarrhea and vomit, varying in severity, being more severe in newborn piglets. The RT-PCR has been the most used diagnostic technique, but serology and immunohistochemistry can also be used. The commercial available vaccine is considered costly and with intermediate effectiveness, consequently complementary biosecurity rules are important to hinder the entry of the agent into the herd. Many studies have been conducted in order to elucidate the epidemiology of the disease, since the route of viral spread among herds is not yet fully established and the economic impact due to high mortality, especially in young animals, significantly impairs the production of pork in affected countries.
