【摘要】：为了调查广东地区猪戊型肝炎感染和流行情况,本研究对2014~2016年广东地区猪场抽取的血样进行抗体检测,以及对猪肝和粪便样品进行病毒核酸检测,PCR结果阳性的样品进行序列分析,确定所感染戊型肝炎病毒的基因型。结果显示,戊型肝炎病毒抗体平均阳性率为69.2%,PCR阳性率为46.7%,对PCR结果阳性的30株样品基因序列分析显示,29株为基因型Ⅳ型,1株为基因型Ⅲ型。
[Abstract]:In order to investigate the infection and prevalence of swine hepatitis E in Guangdong, the antibody was detected in blood samples taken from pig farms in Guangdong from 2014 to 2016. The positive samples of viral nucleic acid detected by PCR in pig liver and feces were sequenced to determine the genotype of hepatitis E virus. The results showed that the average positive rate of hepatitis E virus antibody was 69.2% and the positive rate was 46.7%. The gene sequence analysis of 30 samples with positive PCR results showed that 29 strains were genotype 鈪，
