摘要
为快速诊断猪繁殖与呼吸综合征和猪链球菌病的病因及其有效防治提供参考,对2010年7月贵州省某猪场送检病猪(5例)进行了流行病学调查、剖检病变观察、细菌学和PCR检测,并进行了致病性和药敏试验。结果表明:经流行病学调查和剖检病变观察,该病例为疑似猪繁殖与呼吸综合征病毒和细菌感染所致;细菌分离、生化鉴定为链球菌,猪繁殖与呼吸综合征病毒RT-PCR核酸检测为阳性,链球菌PCR核酸检测为阳性,说明该病例为猪繁殖与呼吸综合征病毒和链球菌混合感染。该链球菌具有高致病性,并对多种药品产生耐药。
The pathogenesis of five sick pigs from the pig farm was determined by epidemiological survey,autopsy pathological observation,bacteriological and PCR detection,and the drug sensitive test was conducted to provide the scientific basis for rapid diagnosis and control of porcine reproductive and respiratory syndrome,and streptococcus.The results showed that five suspected sick pigs were mixedly infected by virus and streptococcus of porcine reproductive and respiratory syndrome(PRRS),and the streptococcus with high pathogenicity was of resistance to many drugs.
