摘　　要：为了解山东地区2011年-2013年猪体携带病原情况,本研究对发病猪场送检的264份病料样品进行病原检测,结果显示发病猪体内主要病原及其分离率分别为：猪繁殖与呼吸综合征病毒43.18%,流行性腹泻病毒27.27%,猪圆环病毒31.64%,猪传染性胸膜肺炎放线杆菌58.33%,副猪嗜血杆菌26.42%,大肠杆菌32.85%,支气管败血波氏杆菌3.12%,绿脓杆菌2.51%。表明引起呼吸系统疾病的病原分离率较高,是导致猪场高发病率与死亡率的重要原因。本研究为有效并针对性地控制相关地区规模化猪场疫病提供了重要数据依据。To investigate the pathogens existed in Shandong area, a total of 264 clinical samples were collected from the sick or dead pigs in 11 large-scale pig farms of 9 areas in Shandong province from 2011 to 2013, and subjected to epidemiological investigations, etiological examination. The results showed that the main pathogens in pigs were porcine reproductive and respiratory syndrome virus, epidemic diarrhea virus, porcine circovirus, Actinobacillus pleuropneumoniae, Haemophilus parasuis,pathogenic Escherichia coli and Bordetella bronchiseptica, Pseudomonas aeruginosa; and the incidence rates were 43.18%,27.27%, 31.64%, 58.33%, 26.42%%, 32.85%, 3.12% and 2.51%, respectively. Among them, the isolation rate of pathogen causing respiratory disease was higher than other diseases. This study provided a basis for controlling the epidemic diseases effectively in scale pig farms.
