When a '''narrow-spectrum antibiotic''' with activity against Gram positive organisms such as penicillin, ampicillin, amoxicillin, clindamycin is administered, the normal bacterial flora is killed and there is '''overgrowth of abnormal flora''', particularly ''E. coli'' and ''Clostridium'' species. '''''Clostridium difficile''''' is one of the organisms linked to the condition.

These bacteria multiply, produce toxins which are absorbed and can lead to a potentially fatal '''enterotoxaemia'''.

This is particularly the case if the antibiotic is administered by the '''oral route'''. Parenteral administration can also lead to problems due to certain antibiotics such as ampicillin and penicillin being excreted in the bile.

This might be the only sign, but if enterotoxaemia is developing, the animal may experience '''systemic signs''' such as: lethargy, inappetance, pyrexia, weakness, coma and death.
