摘要: 江苏某猪场断奶仔猪发生以体温升高为主要临床特征的传染病,发病率和死亡率均较高。本研究对其送检的病死猪样本进行了病原学检测和病原的分离与鉴定,结果从其内脏样本中检测和分离到多种病原。通过细菌学方法分离到副猪嗜血杆菌和大肠杆菌,通过病毒学方法分离到猪圆环病毒2型(PCV-2)。通过临床诊断、病理解剖和实验室确诊,综合判断该猪场感染了PCV-2,并继发感染了副猪嗜血杆菌和大肠杆菌,造成较大损失。

Abstract: A infectious disease hanppened in a hoggery in Jiangsu, The clinical characters of ablactated plglets were high fever, high infectivity and high mortality. Purtenances of the dead swine were detected, and some pathogenies were isolated by laboratory methods. By bacteriological experiments, two bacteria strains were isolated. The one was Haeopilus parasuis(Hps), the other one was E.coli. When the swatch was isolated in PK-15 cell, the cell culture liquid was PCV-2 positive with PCR. We can conclude the hoggery infected PCV-2, which destroyed the immunity of the swinery, it made the swinery infected Haeopilus parasuis and E.coli more easy. 

Key words: PCV-2; E.coli; Haeopilus parasuis; diagnosis
