Table 3 Average nucleotide sequence homology within and between PCV2 genotypes

From: The prevalence and genetic characteristics of porcine circovirus type 2 and 3 in Korea

Nucleotide homology within genotypes (%)   Nucleotide homology between PCV2 genotypes (%)
Genotype PCV2a PCV2b PCV2d
99.4 ± 0.2 (99.1–99.6) PCV2a
98.7 ± 0.5 (98.1–99.4) PCV2b 91.4 ± 0.3 (91.0–92.0)
99.5 ± 0.3 (98.6–100) PCV2d 90.4 ± 0.2 (89.6–91.0) 93.9 ± 0.3 (93.2–94.3)
  1. Homology was determined by the maximum-likelihood method based on the GTR model with G + I in MEGA 6.06 software. Bootstrap values were calculated with 1000 replicates. The analysis includes Korean ORF2 sequences isolated after 2015
