Animals, particularly older ones, may have myocardial haemorrhages as well as petechiation of visceral surfaces and abdominal muscles<sup>merck, ivis</sup>. Pulmonary oedema and congestion is often present and there may be pleural, peritoneal or pericardial effusio. The fluid is variable in volume and can be straw or red coloured, sometimes containing fibrin clots<sup>ivis</sup>. The kidneys often rapidly autolyse, as suggested by the name "pulpy kidney", but this is not a pathognomic finding. The thalamus and cerebellum may alo be abnormally soft, perhaps containing haemorrhages<sup>merk, ivis</sup>. |
− | ivis At necropsy examination, the peritoneal, pleural, and / or pericardial spaces are filled with variable volumes of straw- or red-colored fluid that may contain fibrin clots. Dipstick analysis of urine collected from the bladder frequently reveals the presence of glucose. The renal cortex may be softened (hence the term "pulpy kidney"), although this is a nonspecific autolytic change seen on occasion in small ruminant cadavers. The thalamus and cerebellum may be appreciably soft, with scattered hemorrhages therein. Occasionally, no gross lesions are seen in ovine cases of type D enterotoxemia [24].

− | merck The rumen and abomasum contain an abundance of feed, and undigested feed often is found in the ileum. Edema and malacia can be detected microscopically in the basal ganglia and cerebellum of lambs. Rapid postmortem autolysis of the kidneys has led to the popular name, pulpy kidney disease; however, pulpy kidneys are by no means always found in affected young lambs and are seldom found in affected goats or cattle. Hemorrhagic or necrotic enterocolitis may be seen in goats.
