摘　　要：猪增生性肠炎(PPE)是由胞内劳森氏菌(LI)感染引起的一种以回肠和结肠隐窝内未成熟的肠细胞发生腺瘤样增生为特征的肠道传染病。PPE常引起猪只生长发育阻滞,饲料报酬率严重降低。该病已在全球范围内猪场流行,且其发病率呈上升趋势,给养猪业造成了严重的危害和巨大的经济损失,是影响世界养猪业发展的重要疾病之一。目前国内对该病的研究比较薄弱,应引起足够的重视。文章从组织病理学、细菌分离与鉴定、血清免疫学和分子生物学等方面综述了LI的最新诊断方法研究进展,分析了各种方法的优缺点与实用性,以期为LI感染的鉴定和PPE的有效防控提供参考。Porcine proliferative enteritis(PPE)is an intestinal infectious disease caused by intracellular lawsonella(LI),which is characterized by adenomatous hyperplasia of immature intestinal cells in ileum and colonic recess.PPE often causes growth retardation of pigs and serious reduction of feed return.The disease has been prevalent in pig farms worldwide and its incidence rate is on the rise.It has caused serious harm and huge economic losses to pig industry,and is one of the important diseases that affect the development of pig industry in the world.At present,the research on the disease in China is relatively weak,which should be paid enough attention.This paper reviews the research progress of the latest diagnostic methods of LI bacteria from the aspects of histopathology,bacterial isolation and identification,serum immunology and molecular biology,and analyzes the advantages,disadvantages and practicability of various methods,in order to provide reference for the identification of LI bacteria infection and the effective prevention and control of PPE diseases.
