Antigenic Shift Meaning at Keith Castro blog

Antigenic Shift Meaning. one way flu viruses change is called “antigenic drift.”. if the segment swapped encodes an influenza antigen (such as ha or na) which is targeted by the host immune system, this is termed antigenic shift and can radically alter a host immune system’s ability to recognize the virus (figure 3). Drift consists of small changes (or mutations) in the genes of influenza viruses that can lead to changes in the surface proteins of the virus, ha (hemagglutinin) and na (neuraminidase). antigenic shift is the molecular alteration of an antigen so that the human immune system can no longer recognize it. antigenic shift is a major antigenic change that occurs when an influenza a virus that bears a novel ha (or novel ha and na). antigenic shift, genetic alteration occurring in an infectious agent that causes a dramatic change in a protein called an antigen,. the fast change is called “shift” — different strains of influenza can exchange genetic material if they infect the same cell at the same time. A new “hybrid” strain can emerge with surface proteins that are completely different from the previous year’s epidemic strain. Mutations causing minute changes in the hemagglutinin and neuraminidase antigens on the surface of the influenza virus is termed antigenic drift.
