cold hemoglobinuria.
hemoglobinuria
the presence of free hemoglobin in the urine. In true hemoglobinuria the protein has originated from erythrocytes hemolyzed within the vascular system. In false hemoglobinuria it comes from erythrocytes in the urine that have hemolyzed there, leaving red cell envelopes in the urinary sediment. In both forms the urine is colored dark red to almost black.

bacillary hemoglobinuria
is an acute, highly fatal toxemia of cattle and sheep caused by Clostridium haemolyticum (C. novyi type D). It is characterized by hemoglobinuria, jaundice and sudden death with large, usually single infarcts in the liver.
cold hemoglobinuria
intravascular hemolysis occurs in the blood vessels in the intestinal wall immediately after the calf, rarely an adult, has drunk a large amount of very cold water after a period of deprivation. Transient hemoglobinuria may occur. See also cold anemia.
