【摘要】：为了解贵州省仔猪腹泻病的流行情况,于2011—2015年对贵州省9个地(州、市)271例仔猪腹泻病例进行流行病学调查,并对发病仔猪的肠道内容物和组织样本进行了病原核酸检测与细菌分离鉴定。结果表明:近5年间引起贵州省仔猪腹泻的病原多为病毒性病原和细菌性病原,病毒性病原主要包括猪流行性腹泻病毒(31.4%)、猪瘟病毒(13.7%)和猪传染性胃肠炎病毒(6.3%),细菌性病原主要有大肠杆菌(25.5%)、沙门氏菌(16.6%);从感染类型来看,细菌单独感染所占的比例最高(35.8%),其次为病毒单独感染(27.7%)和病毒与细菌混合感染(20.7%),其他类型的感染均偏低;仔猪病毒性腹泻多发生在秋冬或冬春交替季节及夏秋季(猪瘟),细菌性腹泻多发生在春季和夏季,且引起仔猪腹泻的5种主要疫病的地域分布存在差异。
[Abstract]:In order to understand the prevalence of piglet diarrhea in Guizhou province, 271 cases of piglet diarrhea were investigated in 9 places (state, city) of Guizhou province from 2011 to 2015. The intestinal contents and tissue samples of piglets were detected for pathogenic nucleic acid and bacteria isolation. The results showed that viral and bacterial pathogens were the main causes of piglet diarrhea in Guizhou province in recent five years. Viral pathogens mainly include porcine epidemic diarrhea virus 31. 4, swine fever virus 13. 775) and infectious gastroenteritis virus 6. 3. Bacterial pathogens mainly include Escherichia coli 25. 5 and salmonella 16. 6. From the type of infection, The proportion of bacterial infection alone was the highest (35.8g), followed by the virus infection alone (27.77kb) and the mixed infection of virus and bacteria (20.7g), while the other types of infection were low. Viral diarrhea of piglets occurred in autumn, winter, winter and autumn, and in summer and autumn (CSFV), bacterial diarrhea mostly occurred in spring and summer, and the regional distribution of five major diseases causing diarrhea in piglets was different.
