Sentence examples for multiple reassortment events from inspiring English sources
The second hypothesis is that a currently unknown ancestral rotavirus, of probable porcine origin and having the G11-P[25]-I12 genotypes in a nonhuman Wa genogroup background, might have undergone multiple reassortment events with co-circulating human rotavirus strains, resulting in the different natural reassortant rotavirus strains described in this study.
Multiple reassortment events within wild birds and poultry have resulted in the establishment of H7N9 and H10N8 viruses, respectively, and finally resulted in human infections.
Furthermore, multiple reassortment events are found to happen under natural conditions [11].
The differences were due to multiple reassortment events though all shared a common H-gene lineage.
Although multiple reassortment events happened onward, and several replacements of predominant genotypes were observed from 1996 [48], [49], the Gs/GD/1/96 sublineage continued to be prevalent and circulating in South China in the past eight years.
The H7N9 virus emerged upon multiple reassortment events between different avian influenza viruses.
The emergence of the 2009 H1N1 Influenza pandemic followed a multiple reassortment event from viruses originally circulating in swines and humans, but the adaptive nature of this emergence is poorly understood.
The second hypothesis is that a gradual acquisition of human rotavirus genes occurred after 1 interspecies transmission event, followed by multiple successive reassortment events.
An alternative hypothesis is that rare (porcine?) G11-P[25]-I12 progenitor strares are more widely spread and that genes of such viruses were introduced into the human population by interspecies transmissions, followed by multiple independent reassortment events with human rotavirus strains (G1P[8], G3P[8], G4P[8], G9P[8]).
The recently emerged human G9 RVA strain is believed to have originated from pigs and to have become established in the human population as the fifth major human RVA genotype, after multiple genome reassortment events with typical human Wa-like RVA strains (15 ).
They report today in the Proceedings of the National Academy of Sciences that genes of the 1918 virus were most likely present in swine or human hosts at least 2 and possibly 15 years before the pandemic began and combined to form the deadly virus during multiple reassortments, presumably rare events in which flu viruses exchange genes.
