The porcine transmissible gastroenteritis is a highly severe contagious disease, caused by virus of the Coronaviridae family, genus Coronavirus. Its epizootic shape can reach a rate of up to 100% mortality in piglets under two weeks of age as a result of severe dehydration. In this study fragments of small intestine and stool samples were collected from 75 autopsied pigs from properties. The samples of the fragments were frozen and sent to the Laboratory of Electron Microscopy, Instituto Biológico, SP, Brazil, for histological and transmission electron microscopic analyses. According to histological H&amp;E technique, atrophy, villous necrosis and destruction of the enterocytes were observed in 35 (46.6%) out of the 75 fragments of the small intestine...
