Abstract: According to the complete genome sequences of porcine circovirus type 2 (PCV2) published in GenBank, two pairs of primers were designed. The ORF2 genomes of three PCV2 isolates were amplified from the samples that were similar to those pigs with PMWS, and approximately 17 nm in diameter under electron microscopy. The results of homology showed that nucleotide homology between the three PCV2 isolates was 99.5%-99.8%, and were closely related to the Zhejiang isolate and the Gansu isolate, sharing 99.7% and 90.7%, and displayed 92.0% and 99.4% nucleotide homology with the Sweden isolate and the South America isolate, respectively.

Key words: porcine circovirus type 2; isolation and identification; sequence analysis
