Enterotoxemia in two foals.

The research article presents a case study of two foals from different premises that died from enterotoxemia, a condition caused by toxins produced by Clostridium perfringens bacteria.

Introduction and Background

• The article initiates with cases of two Quarter Horse foals, from different locations, dying from a bacterial infection known as enterotoxemia.
• Enterotoxemia typically results from the production of toxins—specifically, alpha and beta toxins—by a common bacterium named Clostridium perfringens.

Diagnosis and Findings

• The researchers employed a methodology known as ‘mouse protection tests’ to confirm the presence of alpha and beta toxins in the intestines of the foals.
• The particular strain of bacteria isolated from the intestines of each foal was Clostridium perfringens type C.
• Further to this, it was discovered that the intestines of the foals held innumerable numbers of Clostridium perfringens bacteria, giving more weight to the initial diagnosis.

Additional Observations

• Another crucial piece of evidence that supported the diagnosis was the results of a histologic, or tissue, examination.
• During this, the researchers observed the symptoms of hemorrhage and necrosis, both concordant with an enterotoxemia infection.
• Hemorrhage refers to the excessive loss of blood, while necrosis involves the cell death or organ damage.
• Such symptoms are in alignment with what can be expected of a severe bacterial infection.

Conclusion

• In conclusion, the combination of the mouse protection tests, the isolation of the specific bacterial strain, and the results of the histologic examination provided compelling evidence that enterotoxemia, caused by Clostridium perfringens type C, was the cause of death in these foals.
