Name of the disease in English
Bacillary hemoglobinuria
The disease in brief
This is an infection by Clostridia (Cl. hemolyticum and Cl. Novyi) causing hemolysis that is often fatal; the disease is rare, with an increased frequency in summer-autumn. The disease can cause high losses (25%), especially when it is favored by the migration of Fasciola hepatica larvae into the liver parenchyma.
Clinic & diagnosis
The disease is suspected by observing the sudden appearance (a few hours, during the day, 1-2 days) of signs combining:
-Pale or icteric mucous membranes, or black diarrhea, or brown urine.
-A rapid progression towards death, identifiable by: Either marked enophthalmos, or tachypnea, or an expiratory complaint or edema at the entrance to the chest, or a bovine which is reluctant to move.

Differential diagnosis
– Puerperal hemoglobinuria-UR10
– Babesiosis UR14
– Poisoning by cabbages, onions, garlic N24
– Hemolytic jaundice-Various causes -UR14.1
Confirm a suspicion?
Confirmation can be obtained by autopsy of cadavers and isolation of bacteria from an organ sample allowing anaerobiosis to be maintained.
Prognosis and treatment
The prognosis is always poor; early treatment can be attempted at the onset of the disease-febrile phase; high-dose penicillin or tetracycline can be used in combination with support of the general condition by large-volume infusion.
Prevention
Prevention can be done at two levels:
- Control of infestation by Fasciola hepatica which will lead to removing cattle from infested wetlands during the summer period.
- Vaccination against Clostridial infections before the summer period; renewal every year is to be expected, as long as the risk exists.
