Proliferative enteropathy (PE) caused by the obligate intracellular bacterium Lawsonia intracellularis is a disease of high economic impact in swine worldwide. In most other species the disease occurs as a sporadic infection. This paper reports a PE caused by L. intracellularis in a 9-month-old Pura Raza Española filly with a history of profuse diarrhoea. Pathological lesions consisted of a severe proliferative enteritis associated with argyrophilic bacteria in the apical cytoplasm of proliferating crypt epithelium. Characteristic PCR products confirmed the presumptive diagnosis of L. intracellularis infection. To our knowledge this is the first report of PE in a horse in Europe caused by L. intracellularis.
由专性细胞内细菌胞内劳森菌引起的增生性肠炎（PE）是一种在全球范围内对养猪业具有重大经济影响的疾病。在大多数其他物种中，该疾病以散发性感染的形式出现。本文报道了一匹9个月大的西班牙纯种小母马发生的由胞内劳森菌引起的增生性肠炎，该马有严重腹泻病史。病理病变包括严重的增生性肠炎，在增生的隐窝上皮细胞顶端细胞质中存在嗜银菌。特征性的PCR产物证实了胞内劳森菌感染的初步诊断。据我们所知，这是欧洲首例由胞内劳森菌引起的马增生性肠炎报告。
