Equine proliferative enteropathy (EPE) is an equine infectious disease that can lead to severe weight loss and hyperplasia of the intestinal mucosa due to infection with Lawsonia intracellularis. In this study, we investigated the prevalence of EPE in a major Thoroughbred breeding area: Hidaka district, Hokkaido, Japan. Of the 252 symptomatic horses that we tested, 192 EPE cases (76.2%), including 8 fatal cases, were confirmed from April 2015 to March 2020 by etiological and/or serological investigation. Most of the EPE cases were observed in foals (88.5%), with fewer cases in yearlings (7.3%) and adults (4.2%). Asymptomatic infection was observed in 62.9% of the horses kept with affected horses. These results suggest that EPE is an enzootic disease in Hidaka district.
马增生性肠炎（EPE）是一种马传染病，由于感染胞内劳森菌可导致严重体重减轻和肠黏膜增生。在本研究中，我们调查了日本北海道日高地区一个主要纯种马养殖区的EPE流行情况。在我们检测的252匹有症状的马中，通过病因学和/或血清学调查，从2015年4月至2020年3月确诊了192例EPE病例（76.2%），其中包括8例死亡病例。大多数EPE病例见于驹（88.5%），周岁马（7.3%）和成年马（4.2%）病例较少。在与患病马同群饲养的马匹中，62.9%观察到无症状感染。这些结果表明EPE在日高地区是一种地方流行性疾病。
