Part Descriptions
LP21134-9 Powassan virus
The Powassan virus is a tick-borne encephalitis virus related to the classic TBE flavivirus. This disease had its earliest origins in the town of Powassan, Ontario, found in a young boy who eventually died from it. Powassan virus is transmitted by I.cookei among small mammals in eastern Canada and the United States, where it has been responsible for 20 recognized cases of human disease. Other ticks may transmit the virus in a wider geographic area, and there is some concern that I.scapularis (also called I.dammini ), a competent vector in the laboratory, may become involved as it becomes more prominent in the United States.

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.
