Enterotoxemia in Sheep and Goats

It is associated with abortions and perinatal mortality but its main impact is on males. Advanced postmortem autolysis often prevents definitive diagnosis of enterotoxemia at necropsy due to the extensive overgrowth of clostridial organisms after death of the animal. It has caused massive mortalities in wild ungulates such as saiga antelope Saiga tatarica.

Guy Sheppard or Veterinary Pathologist Dr. Department of Agriculture and Colorado counties cooperating. Typical clinical signs include:. On necropsy examination, a large section of the small intestine can appear dark red to purple Figure 1. Murray E.

These changes cause the clostridial organism to grow rapidly and produce a powerful toxin that causes death in a few hours. An ELISA kit is also available for the detection of several overeatihg toxins including the epsilon toxin and identification of the C. When administering drugs, always follow label instructions. Vaccination of the ewe in late pregnancy, four weeks before lambing, offers protection. Withdrawal time 42 days. Vaccination at the time of docking or castration of lambs may not be protective because it takes about 7 to 10 days for antitoxic immunity to develop. Diagnosis can be confirmed by positive identification of enterocolitis, anaerobic culture, and identification of Clostridium perfringens type D from the feces or intestinal contents from clinical or necropsy specimens of affected animals.

Microscopic ulcers and superficial mucosal necrosis with numerous associated clostridial organisms and mild suppurative inflammation may be present in intestinal specimens. Should an animal die, a necropsy can be performed to look for evidence of disease. These toxins can cause damage to the intestine as well as numerous other organs. Young animals are most susceptible. Colorado State University, U. Guy Sheppard or Veterinary Pathologist Dr. Effective vaccines are commercially available to prevent enterotoxemia in sheep and goats.
