WebNov 9, 2024 · The nature of the tripartite genome endows the potential for genetic reassortment of TSWV among different isolates coinfecting the same plant (Tsompana et al. 2005). Indeed, reassortment has been shown to occur spontaneously in TSWV, and to play an essential role in the emergence of new TSWV variants with distinct pathogenicity … WebFeb 13, 2012 · Reassortment of segmented viruses is a key mechanism for rapid novel virus creation. At least two human influenza pandemics in the last century were linked to lineages where some number of genomic segments reassorted with a genome of nonhuman origin ( 1, 2 ). This fact was reinforced by the emergence of the 2009 H1N1 pandemic …

WebJan 25, 2024 · Background Reassortment between human and avian influenza viruses (AIV) may result in novel viruses with new characteristics that may threaten human health when causing the next flu pandemic. A particular risk may be posed by avian influenza viruses of subtype H9N2 that are currently massively circulating in domestic poultry in … WebIn late summer through early winter of 1998, there were several outbreaks of respiratory disease in the swine herds of North Carolina, Texas, Minnesota, and Iowa.

WebFeb 16, 2012 · Summary. Genetic reassortment plays a vital role in the evolution of the influenza virus and has historically been linked with the emergence of pandemic strains. Reassortment is believed to occur when a single host - typically swine - is simultaneously infected with multiple influenza strains. The reassorted viral strains with novel gene … WebWhether genetic reassortment of human and avian influenza viruses occurs during interpandemic periods and how often humans are infected with such reassortants is not known. To provide this information, we used dot-blot hybridization, partial nucleotide sequencing and subsequent phylogenetic analysis to examine the 6 internal genes of 122 ... WebVirus evolution is more complex as it is highly prone to horizontal gene transfer, genetic recombination and reassortment. Moreover viral evolution should always be considered as a process of co-evolution with its host, as a host cell is inevitable for virus reproduction and hence, evolution.
