DG – Enterotoxemia
Synonyms
Lamb dysentery (type B), necrotizing hemorrhagic enteritis (type C), pulpy kidney disease (type D)
Name of the disease in English
Enterotoxemia caused by Clostridium perfringens toxinotypes A (yellow lamb disease), B (lamb dysentery, hemorrhagic enteritis), C (hemorrhagic enteritis, struck), D (pulpy kidney disease), E
The disease in brief
The disease, more common in small ruminants, is due to the intestinal proliferation of anaerobic bacteria Clostridium perfringens (Also Clostridum sordellii); the bacteria is common in the digestive tract of ruminants: it proliferates due to imbalances in the intestinal flora most often caused by a diet rich in concentrates, rationing errors, parasitism, ileus, etc.
Clinic & diagnosis
Enterotoxemia is suspected in the event of sudden death (within a few hours) sometimes preceded by the appearance of digestive signs (hemorrhagic or tarry diarrhea, etc.) and/or hyper nervous signs (agitation, convulsion, etc.).

Differential diagnosis
-Lightning-N310
-Acute lactic acidosis-MET3
-meteorization (gaseous, foamy)-DG22
-Bacterial meningoencephalitis NV13.1
-Tetany of milk-fed calves NV14.6
-Hypomagnesemia (grass tetany) NV14.2
– Rage LV18.1
– Lead poisoning TX4
-other poisonings (yew, oenanthe, etc.) N133
Confirm a suspicion?
It is at the autopsy (carried out within 8-12 hours after death) that we will find signs suggestive of enterotoxemia (variable depending on the forms encountered): effusions in the cavities, rapid decomposition of the corpse, necrohemorrhagic enteritis, degenerative nephritis and hepatitis; take a sample (if the time is short enough) of the intestinal contents, filling the bottle -anaerobiosis- to ask the laboratory for a count of Clostridium
Prognosis and treatment
Too rapid an evolution prevents its implementation.
Prevention
-Prevent imbalances and avoid sudden dietary changes in cattle already receiving an intense diet.
–Ensure food storage hygiene and avoid grazing after spreading anaerobically decomposing materials.
– Implement preventive vaccination in high-risk herds
