A Brief Overview of Porcine Enteric Diarrhoea Virus

PED, which was initially discovered in English feeder and fattening pigs in 1971, is a destructive intestinal illness that expresses itself as intermittent outbreaks during the winter, causing devastation to breeding farms. PED resembles transmissible gastroenteritis (TGE), but has less of an effect on suckling pigs (<4- to 5-week old); this is what allowed PED to first be distinguished from the TGE virus and other recognized enteropathogenic agents. The disease was dubbed “epidemic viral diarrhoea (EVD)” as it spread across Europe.
