On '''post-mortem examination''', blood is watery and carcasses are [[Icterus| icteric]] and gelatinised. Numerous petechiae may be present within the mucous membranes and heart.

Ulcers are often evident in the [[Abomasum | abomasum]] of ruminants and are surrounded by haemorrhagic zones. Urine is dark brown due to the presence of [[Bilirubin | bilirubin]]
