摘要: 从辽宁某猪场采取病料,经处理后接种Marc-145细胞进行PRRSV分离,结果有2份病料在该细胞上盲传后可见典型的CPE,经测定其毒价为10-6.5TCID50/mL。间接免疫荧光试验可见黄色荧光,用电镜对纯化的病毒进行观察,可见有囊膜包裹的圆形病毒粒子,直径约为50~70 nm。该病毒对氯仿、紫外线、酸碱度变化和热敏感。对有CPE的细胞培养物进行RT-PCR,结果为阳性。接种试验动物出现典型的PRRS临床症状和死亡。结果表明,成功分离到一株PRRSV。

Abstract: To isolate porcine reproductive and respiratory syndrome virus (PRRSV), the morbid materials were collected from some swine farm of Liaoning province and inoculated on Marc-145 cell after disposal. After blind transfer of culture, two portions showed typical cytopathic effect (CPE). TCID50 of virus was 10-6.5/mL. By the indirect immunofluorescence experiment,the yellow green fluorescence occurred in the cell cytoblastema. The virus appeared typical porcine reproductive and respiratory syndrome virus form: diameter was about 50-70 nm,circle with peplos and peplomer. It was inactivated by chloroform, ultra-violet,pH variation, and heat. The cell cytoblastema which showed CPE were tested by RT-PCR showed positive. The laboratory animals appeared obvious clinical symptom and death after inoculation. The result showed that PRRSV was identified from Liaoning province.

Key words: porcine reproductive and respiratory syndrome virus (PRRSV); isolation; identification
