AB  - The <I>ORF2</I> genes of 10 isolated Porcine Circovirus type 
  2 (PCV2) strains in Yunnan Province of China were sequenced, analyzed and further 
  compared with the sequences of 24 strains retrieved from GenBank. The results 
  showed that the <I>ORF2</I> genes of the 10 strains in Yunnan Province shared 
  sequence identity of 98.7-100.0% on nucleotide acid level and of 96.2-100.0% 
  on amino acid level. Moreover, Yunnan strains and the other 24 strains retrieved 
  from GenBank shared 91.0-99.7% nucleotide and 80.3-97.4% amino acid sequence 
  similarity. Based on the phylogenetic tree analysis, these strains could be 
  divided into five genotypes (PCV2a-PCV2e) and all the Yunnan strains fall into 
  PCV2b genotype. Compared with other PCV2b strains, nine point mutations of amino 
  acid residues were identified only in Yunnan strains which might be essential 
  for controlling PCV2 infection in Yunnan Province, China.
