Abstract

Five outbreaks of caprine enterotoxaemia in Rio Grande do Sul, Brazil, were studied. The animals were found dead or had a clinical course that usually lasted 2-3 hours. From two farms a clinical manifestation period of 12 hours was reported. Clinical signs were characterized by depression, marked abdominal discomfort, profuse watery diarrhea with fibrin clots, and death. Thirteen necropsies were performed and hydropericardium, hydrothorax and hydroperitoneum were commonly found. The mucosa and serosa of the colon were congested, and its contents was watery with multiple fibrin clots. Serosal hemorrhages and fibrin clots in the gallbladder were also seen. Fibrinous colitis and thyphilitis were the most frequent histological changes. Cerebral microangiopathy was observed in one case, which was characterized by acute perivascular proteinaceous edema around arterioles of the nucleus caudatus and thalamus. Large numbers of Gram-positive rods, often in clumps and with morphology consistent with Clostridium perfringens, were seen in intestinal smears. The intestinal contents of six goats were positive for epsilon toxin by mouse neutralization test. These findings suggest that enterotoxaemia is an important disease of goat flocks in southern Brazil.
