What is it?
Enterotoxemia is a serious disease mainly affecting sheep and goats, caused by toxins produced in the intestine. It often progresses very quickly and can lead to the animal's death within hours. This disease is well known to Tunisian farmers, particularly in young, well-fed animals.
Enterotoxemia is caused by the excessive multiplication of Clostridium bacteria, particularly Clostridium perfringens, which are normally present in small amounts in the intestine. When intestinal conditions change, such as after a sudden dietary shift, these bacteria multiply rapidly and release dangerous toxins. These toxins then enter the bloodstream and affect several organs.
Sudden dietary changes, such as an abrupt shift to a diet rich in grains or young grass, greatly increase the risk. Young, healthy, well-fed animals are often the most affected, as are poorly vaccinated flocks. Stress, overgrazing, and insufficient enclosure hygiene can also promote the disease's occurrence.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
Signs may include sudden death without prior visible symptoms, or nervous disorders such as convulsions, staggering gait, and loss of balance. Abdominal pain, bloating, and diarrhea are sometimes also observed. In peracute forms, the animal may be found dead without showing any apparent sign.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Transmission
Enterotoxemia is not a contagious disease transmitted from one animal to another. The responsible bacteria are already naturally present in the animal's intestine and become dangerous only under certain conditions favorable to their proliferation. It is therefore an internal imbalance rather than direct transmission between animals.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
If signs suggestive of enterotoxemia appear, it is essential to contact a veterinarian quickly, as the disease can progress very fast. Only a professional can assess the situation and recommend appropriate care. Never attempt to treat the animal yourself without veterinary advice.
Prevention
Regular flock vaccination is the most effective prevention method against enterotoxemia, to be discussed with a veterinarian according to an appropriate schedule. It is recommended to introduce dietary changes gradually to avoid disrupting the intestinal flora. Good hygiene and grazing management also help reduce risks.
