Plain-English summary
A mare was suffering from a serious illness that seemed to be linked to an allergic reaction to certain parasites. She showed signs like weight loss, diarrhea, and sores on her hooves. Unfortunately, her health declined quickly, and she was put to sleep so that a thorough examination could be done. The examination revealed chronic inflammation in her pancreas and intestines, along with other liver issues, which suggested that her condition was likely caused by an allergic response to migrating parasite larvae. Sadly, despite the findings, the exact cause of her illness was not clear, and the treatment options were limited.
Abstract
A generalized debilitating disease in a horse was believed to be related to hypersensitivity to migrating strongyle larvae. The clinical signs included weight loss, diarrhea, and ulcers on all 4 coronary bands. The mare's condition deteriorated rapidly, so the mare was euthanatized and necropsied. The major histopathologic findings were chronic multifocal eosinophilic pancreatitis, hepatic portal fibrosis, biliary hyperplasia, and chronic ulcerative eosinophilic colitis. This case was similar to previously reported cases of chronic eosinophilic gastroenteritis in horses. Although the etiologic agent was not evident, the distribution and character of the lesions were consistent with a hypersensitivity response to migrating parasitic larvae, most probably Strongylus equinus.
