The molecular characterization of partial- length genomic segment 2 of porcine picobirnavirus (PBV) strains and the development of a specific reverse transcription-PCR (RT-PCR) assay for detection of virus in feces are reported. Phylogenetic analysis indicated that the studied porcine isolates were more closely related (>85% identity) to human PBV belonging to genogroup I than to the other porcine PBV described so far. Analysis by RT-PCR and polyacrylamide gel electrophoresis of fecal samples collected in Venezuela and Argentina showed that PBV circulate at high frequencies in piglets.
报道了猪微小双股RNA病毒(PBV)毒株全长基因组2片段的分子特征,以及用于检测粪便中该病毒的特异性逆转录-聚合酶链反应(RT-PCR)检测方法的开发。系统发育分析表明,所研究的猪分离株与属于基因组I的人类PBV的亲缘关系比与迄今描述的其他猪PBV更密切(同一性>85%)。对在委内瑞拉和阿根廷采集的粪便样本进行RT-PCR和聚丙烯酰胺凝胶电泳分析表明,PBV在仔猪中高频率传播。
