摘　　要：为调查闽西地区猪增生性肠炎发病情况,应用PCR技术对2008年龙岩学院动物医学研究所接诊的6周龄-20周龄腹泻病例进行了胞内劳森氏菌检测。结果表明,被检测的8个猪场均存在胞内劳森菌感染,61份粪便样品中21份（44.2%）呈阳性,其中6周龄-8周龄猪阳性率为46.7%,9周龄-13周龄生长猪阳性率为47.8%,14周龄-20周龄阳性率为42.9%。由此说明闽西地区猪场普遍存在猪增生性肠炎的感染。The epidemiology investigation of porcine proliferative enteritis in west of Fujian province of China were carried out by Polymerase chain reaction method.61 fecal samples collected from diarrhea case with the age of 6-20 weeks were from 8 pig farms.Fecal samples were submit to animal medical institute of Longyan university to detect Lawsonia intracellularis.The result showed that porcine proliferative enteritis was a common disease in pig farms in west of Fujian province with 27 of the 61（44.2%）samples positive.The PPE prevalence of 6-to 8-week-old was 46.7% while 47.8% and 42.9% that of 9-to 13 week-old and 14-to 20 week-old pigs respectively.
