For 10 points, name these viruses that cause a disease with "Spanish," "avian," and "swine" types.
The relative susceptibility of this agent to the MF59 adjuvant has caused some controversy. The classic example of antigenic shift concerns their mixture. They bind to a cell as a result of the interactions of sialic (SAHY-al-ick) acid and the proteins hemagglutinin (HEEM-uhg-gloot-in-in) and neuraminidase (NYOOR-uh-min-uh-dase). From the family orthomyxoviridae (AWR-thuh-micks-oh-veer-ih-day), their "A" subtype, not "B" or "C," contains the (*) H1N1 strain.
