2012年我国部分地区猪瘟流行病学调查及 E2部分基因遗传演化分析
Epidemiological Survey of Classical Swine Fever in Partial Areas of China in 2012 and Genetis Analysis of E2 Gene
摘要
Abstract
To investigate the variation of Classical swine fever virus (CSFV)in China,samples collected in 2012 from 12 provinces were positive in classical fever virus detected by RT-nested PCR and sequenced.To gain insight into the molecular epidemiology of CSFV in China,we analyzed E2 gene of 107 isolates,The result revealed that all of these 107 isolates belonged to subgroup 1.1and 2.1.There were 48 isolates (45% of total)classified in subgenotype 1.1,and 59 isolates (55 % of total)classified in subgenotype 2.1, and none of isolates were classified in subgenotype 2.2 or subgenotype 2.3.All viruses of subgenotype 1.1 were close to HCLV strain and far from Shimen strain.So they were presumed to be lentogenic strains. Most of viruses belonged to 2.1.The isolates of 2.1b were more prevalent than others and the viruses of 2.1c had a tendency to be popular.关键词
