This is antigenic shift.
The other type of change is called"antigenic shift.".
The bacterium has changed its makeup(antigenic shift) limiting recognition by the patient's immune system.
The infuenza virus can change these N and H molecules,which is called antigenic shift.
This is called antigenic shift.
Influenza viruses change by two processes, antigenic drift and antigenic shift.
The resulting rapid change in viral genetics produces antigenic shifts, which are sudden changes from one antigen to another.
There is not evidence that vaccines cause major changes in the virus, such as an antigenic shift.
Antigenic shift is an abrupt, major change in an influenza A virus, resulting in new HA and/or new HA and NA proteins in influenza viruses that infect humans.
This is called an antigenic shift.
The influenza virus has an ability to change its H and N molecules,a phenomenon called antigenic shift.
It is feared that if the avian influenza virus undergoes antigenic shift with a human influenza virus, the new subtype created could be both highly contagious and highly lethal in humans.
Influenza viruses can change in two different ways- antigenic drift and antigenic shift.
Antigenic shift leads to a new influenza A subtype or one that has emerged from an animal population that is so different from the same subtype of viruses in humans that most people do not have immunity to the new type of virus.
Influenza virus produces mutations using two different processes: Antigenic Drift and Antigenic shift.
Whilst flu viruses are transforming by antigenic drift constantly, antigenic shift occurs only occasionally.
For example, the swine flu of 1918 was named H1N1, while a later strain of influenza which was found to have changed its hemagglutininmolecules was named H2N1, and an even later influenza was found to have changed both its surface molecules(double antigenic shift), and was named H2N2.
Influenza viruses are changing by antigenic drift all the time, but antigenic shift happens only occasionally.
Swine flu and bird- or avian- flu, refer to viruses that were common in pigs or birds, butnot in humans, until an antigenic shift occurred.
