Each value is indicated as first the amino acid difference and then the position number is given. Boldface, nonconservative amino acid substitution; IPS, identical protein sequences. Underlining indicates a novel mutation described for ISAV. Superscript letters: a, amino acid difference also found in virulent isolate ISAV1; b, amino acid difference also found in virulent isolates ISAV1, ISAV4, ISAV5, and low-virulence or avirulent isolates ISAV10, ISAV11, and SK779; c, amino acid difference also found in low-virulence or avirulent isolates ISAV8, ISAV10, ISAV11, and SK779; d, amino acid difference also found in low-virulence or avirulent isolates ISAV8 and SK779; e, amino acid difference also found in virulent isolate ISAV4 and avirulent isolate SK779/06; f, amino acid difference also found in virulent isolate ISAV8; g, amino acid difference also found in avirulent isolate SK779; h, amino acid difference also found in virulent isolates ISAV5, ISAV6, and ISAV7; i, amino acid difference also found in virulent isolates ISAV1, ISAV3, ISAV4, ISAV5, and low-virulence isolates ISAV8, ISAV10, and ISAV11; j, amino acid difference also found in virulent isolate ISAV5.
