Comparison of amino acids of capsid protein E region of the 26 FCV isolates. A Diversified mutations in the E region of capsid protein, the size of the graphic character at corresponding site is proportional to the occurrence frequency of amino acids at a certain site. B Specific identification sites of different genotypes are marked with black triangles at the bottom (▲), seven virulence factor-related sites are indicated by black triangles at the top (▼), “-” indicates missing regions
