Equine eosinophilic enteritis

Equine eosinophilic enteritis (EEE) is a rare digestive disorder usually associated with a multisystemis epitheliotropic syndrome. Affected animals develop diarrhea, weight loss and hypoalbuminemia. The etiology is unknown, although traditionally a hypersensitivity reaction of parasitic origin or a paraneoplastic effect mediated by IL5 have been suspected. In a retrospective study in England, the authors describe that a seasonal character (late summer and autumn) and a particular geographic concentration of cases could suggest some kind of environmental factor or management practices as responsible for the disease. Simultaneously, the study also reveals that young animals are at increased risk of developing EEA
