1Distinct amino acids are shown bold-faced. 2The position of the amino acids are based on the full-length deduced amino acid sequences of the nucleocapsid protein of TN isolate (GenBank accession No. HQ728387). Except for the above positions, all other encoded amino acids are identical among all 13 isolates.
