Synonyms Antigenic Drift ; Antigenic Shift ; Change of Antigenic Properties by Mutations ; Change of Antigenic Properties by Rearrangement of Viral Genome Segments Definition Viral infections result in a constant competition between the virus and host to prevail over each other. The virus tries to ...
The students make the models from styrofoam cups, yarn and pipe cleaners and examine how they evolve. A discussion is made on the genetic content of the virus and the creation of other strains. The class performs a reassortment activity that helps the students visualize viral evolution....
Antigenic drift rarely occurs in ICVs and IDVs. It seems that the last antigenic drift in ICVs occurred 30 years ago (Su et al., 2017; Matsuzaki et al., 2016). The antigenic shift causes drastic changes in the genome of the IVs, and it is more prevalent in birds. Since the genome ...

As a consequence of antigenic drift, the composition of the influenza vaccine must be carefully evaluated and updated annually to cover those strains likely to be circulating. Antigenic shift refers to the emergence of a novel influenza virus in humans, due to direct introduction of an avian ...
the variants NP, dinitrophenyl (DNP) and trinitrophenyl (TNP) (Fig.6a). ACKR4+/−mice were immunized with NIP-KLH. After the onset of BEMrecycling, we rechallenged in the same foot with NP, DNP, followed by TNP-KLH. Three days after the last injection we observed a shift in ...
these variants had not reached the level of prevalence to illustrate a great effect on disease rates and shift in the distribution of confirmed cases [110]. Epsilon variant (B.1.427/B.1.429) First discovered in an isolate from Southern California in July 2020, CAL.20C was responsible for an...
