Genetic Variation Analysis of PCV2 Isolates in Liaoning Area from 2013 to 2015
摘要
Abstract
In order to understand the genetic variation of porcine circovirus type 2(PCV2)in Liaoning from 2013 to 2015,the full sequence of PCV2 gene was amplified by PCR from the PCV2 positive samples in Liaoning province,and the sequence alignment and genetic variation analysis were conducted by DNA Star.The results showed that the full genome length of 15 PCV2 strains were 1 767 bp and 1 768 bp,the gene nucleic acid sequence homology was 94.4％to 99.8％;11 strains of 15 PCV2 strains belonged to PCV2b genotype,4 strains belonged to genotype PCV2a.The results showed that a variety of serotype PCV2 were epidemic at present,the immune strategies according to the dominant serotypes should be developed.关键词
