The nucleoprotein (NP) gene of swine influenza H1N1 variant, A/Sw/Quebec/5393/91 (SwQc91) was sequenced. When compared with other H1N1 strains, 12 amino acid (aa) replacements were observed in the 101–484 aa region of the NP protein including two aas, 345 and 430, representing the unique lineage of swine viruses. Phylogenetic analysis showed a drift in the NP gene. |
