MOLECULAR EPIDEMIOLOGICAL INVESTIGATION INTO PORCINE CIRCOVIRUS TYPE 2 BETWEEN 2008 AND 2011 IN SOME REGIONS OF CHINA
摘要
Abstract
To investigate into molecular epidemiology of Porcine circovirus type 2（PCV2）,a total of 452 serum samples were collected between 2008 and 2011 from healthy or diseased pigs of 12 provinces of China.PCV2 was detected in 354（78.3%） serum samples.Thirty one PCV2 isolates were obtained and their ORF2 nucleotide sequences were amplified,cloned and sequenced.Data were analyzed by molecular biological software.All of 31 isolates belonged to PCV2b,of which 21 were grouped into PCV1A/1B and 10 into PCV1C.A comparison of the deduced amino acid sequences of these PCV2 isolates revealed specific mutation sites within PCV2 subgroups.PCV2 1A/1B has been a dominant subgenotype in China since 2008.However,this status may change in future as PCV2 1C is on the rising tendency.关键词
