LP182335-2   Influenza virus B Victoria lineage
Influenza B viruses can be separated into two major lineages, B/Victoria and B/Yamagata. Recent studies have shown that the two major lineages may differ in terms of epidemiology and risk of secondary infection. One study found that patients with confirmed influenza B Victoria lineage infections were significantly younger compared to patients infected with the Yamagata lineage. PMID: 25034374 A separate study found that Victoria-lineage viruses were associated with a significantly higher risk of secondary infection among patients' household contacts who were 15 years old or younger than among those older than 15, but the same did not hold true for Yamagata-lineage viruses. PMID: 26400854 Studies have also shown that genetically distinct lineages like B/Victoria/2/87 can cocirculate in the population and that the reassortment among these strains plays a role in generating the genetic diversity of influenza B viruses.

LP6304-2   HAI
The hemagglutination-inhibition assay (HAI) can be used to identify subtypes of hemagglutinin producing viruses, such as Influenza. HAI can also be used to identify the subtype-specificity of antibodies against the virus. Normally, Influenza's hemagglutinin glycoprotein binds to receptors on the surface of red blood cells, causing them to agglutinate. If antibodies specific to the virus are present in the patient sample, they will bind to the virus, which prevents the virus from binding to the red blood cells and therefore prevents agglutination. To determine which subtype of virus is present, a viral isolate is tested against a series of antibodies with known subtype specificities. Whichever antibody inhibits red cell agglutination identifies the viral subtype. Similarly, antibody specificity is identified by testing the patient sample against known virus subtypes.
