Arquivos da Escola de Veterinaria Universidade Federal de Minas Gerais 33(2): 217-222
Six outbreaks of edema disease were described in weaned pigs (50-65 days old) in the state of Minase Gerais, Brazil. The symptoms were mainly diarrhea, staggering gait, muscular tremors and paralysis. Postmortem findings included edema of the eyelid, forehead, greater curvature of the stomach, and varying amounts of fluid present in the pericardial sac and the pleural and peritoneal cavities. In the intestines there was some degree of dilatation and congestion and excess of mucous material, especially in the duodenum. The renal cortex was somewhat pale; the medullar was congested and enlarged. Hemolytic Escherichia coli was frequently recovered from stomach and duodenum contents.
