2014-2015年,中国多个省份的大型猪场发生了猪瘟(CSF)流行,并新发现了一种2.1d亚型猪瘟病毒(CSFV)。对2014-2015年分离的猪瘟病毒株、2015年新分离的18株猪瘟病毒株和2014-2015年分离的其他43株猪瘟病毒株以及163株猪瘟参考分离株的系统发育关系、遗传多样性和流行状况进行全面分析。2014-2015年分离的52株为2.1d亚基因型,9株为2.1 1b亚基因型。两个亚基因型分离物表现出独特的分子特征。此外,发现2.1d分离株可能与2.1b分离株存在分化。这项研究表明,中国的猪瘟仍将是大流行。
In 2014–2015, the epidemic of classical swine fever (CSF) occurred in many large-scale pig farms in different provinces of China, and a subgenotype 2.1d of CSF virus (CSFV) was newly identified. The phylogenetic relationship, genetic diversity, and epidemic status of the 2014–2015 CSFV isolates, 18 new CSFV isolates collected in 2015, and 43 other strains isolated in 2014–2015 were fully analysed, together with 163 CSFV reference isolates. Fifty-two 2014–2015 isolates belonged to subgenotype 2.1d and nine other isolates belonged to subgenotype 2.1b. The two subgenotype isolates showed unique molecular characteristics. Furthermore, the 2.1d isolates were found to possibly diverge from 2.1b isolates. This study suggests that the Chinese CSFVs will remain pandemic.
