湖南省某规模猪场的保育猪在转至育肥舍10 d后(约80日龄)陆续出现发病死亡情况.为确诊病情,查找病因,采集不同年龄段的猪血清进行猪瘟病毒(CSFV)、猪繁殖与呼吸综合征病毒(PRRSV)、圆环病毒2型(PCV2)抗体检测,同时对4头发病猪进行剖检观察,并采集病料进行CSFV、PRRSV、PCV2病原检测以及细菌分离、药敏分析.结果显示:疫病发生前后的生猪CSFV抗体均不理想,无高抗体水平个体出现,但病原检测为阴性;生猪PRRSV、PCV2抗体整体上均经历了母源抗体下降、发病时抗体又上升的阶段,且病原检测均有阳性样本存在;在病料中分离到葡萄球菌、链球菌、副猪嗜血杆菌.由此推断,该次生猪发病原因可能为PRRSV、PCV2以...

The nursery pigs died successively after 10 days when they were transferred to fattening houses in a largescale swine farm in Hunan Province. In order to confirm the epidemic and find out relevant pathogens,serum samples were collected from these pigs at different ages to detect antibodies against classical swine fever virus(CSFV),porcine reproductive and respiratory syndrome virus(PRRSV)and porcine circovirus virus 2(PCV2),meanwhile,four infected pigs were autopsied for observation,and pathological tissue samples were collected and pathogen detection of CSFV,PRRSV and PCV2,bacteria isolation ...
