A new member of the arenavirus family, Lujo virus, has been identified in patients who died during an outbreak of hemorrhagic fever in late 2008. Sequence analysis reveals that Lujo is a new arenavirus, genetically distinct from other members of the family which includes Lassa virus. A patient with unexplained hemorrhagic fever was identified in …

The microneutralization assay is another technique used by the Centers for Disease Control and Prevention to determine that some adults have serum cross-reactive antibodies to the new influenza H1N1 virus. Let’s explore how this assay works. Viral replication is often studied in the laboratory by infecting cells that are grown in plastic dishes or flasks, …
Centers for Disease Control and Prevention have determined that some adults have serum cross-reactive antibodies to the new influenza H1N1 virus. One of the techniques used to reach this conclusion is the hemagglutination inhibition (HI) assay. How does this assay work? To understand the HI assay, we must discuss the hemagglutination assay. Influenza virus particles …
