7、One fear, however, is that H5N1 might become better at infecting humans by swapping genetic parts (reassortment) with types of flu virus that already infect humans easily.
2、Neuraminidase gene reassortment of low pathogenic avian influenza viruse N2 subtype among domestic ducks in Eastern China
6、Sequencing of all eight gene segments found no evidence of genetic reassortment with human or pig influenza viruses and no evidence of significant mutations.
3、Each additional human case increases opportunities for the virus to improve its transmissibility, through either adaptive mutation or reassortment.
9、Dynamic gene mutation and the reassortment of genes have been considered as the key factors responsible for influenza a virus virulence and host tropism change.
8、The first is a “reassortment” event, in which genetic material is exchanged between human and avian viruses during co-infection of a human or pig.
1、At least some pandemic viruses are known to have emerged following a reassortment event.
5、Some currently circulating H5N1 strains are fully resistant to these the M2 inhibitors. However, should a new virus emerge through reassortment, the M2 inhibitors might be effective.
4、The virus is produced by a reassortment, in which human-adapted H1N1 swaps genes with an H2N2 bird flu.
