Previously, EAswH1N1 viruses had only been detected in Europe and Asia (4-6), and Mexico is the only country in the Americas where TRswH3N2, CswH1N1, and EAswH1N1 lineages co-circulate and exchange genome segments by reassortment
In conclusion, the first detection of influenza antibodies in Pecari tajacu confirmed the virus circulation in this population, thus, from now on, the serological surveillance is required to monitor the circulation and further studies are required to understand the role of peccaries on the pathogen dissemination and on risks of reassortment
events with pigs.
The series consists of five books, including "The Song of the Jubilee," "The Gambit with Perfection," "The Synthesis and the Animus," "The Descent into the Maelstrom," and "The Restoration of Flaws." The books touch upon various parts of a futuristic world, including the deadly surface of the Earth, where humans succumb to the Reassortment
Strain, a synthetic organism created during a century-long war.
The emergence of this dominant H9N2 virus, Liu continued, was the first step in the genesis of the H7N9 viruses because it greatly increased the likelihood of reassortment
between H9N2 and other flu subtypes.
These strains which include genes derived by reassortment
from human swine and avian viruses have become a major cause of swine influenza in North America.
Further tests based on the tracheal swab samples confirmed reassortment
origin of the new virus.
Zhu Huachen, one of the leading authors of the paper, said that H7 viruses probably transferred from ducks to chickens on at least two independent occasions and that reassortment
with H9N2 viruses generated the H7N9 outbreak lineage.
Sequence analysis suggested that the virus was a reassortment
generated from avian viruses circulating in wild birds and ducks (3).
Of the 581 HA sequences, six swine strains already contain the standard HA mutations necessary for human adaptation, and are thus capable of entering the human population either directly or via genetic reassortment
, Sasisekharan said.
Polymerase chain reaction analysis (PCR) will be used to determine the absence of recombination or reassortment
to test our hypothesis that y-irradiation is able to produce viruses that can induce livevirus-like immunological responses, remain transcriptionally active but unable to undergo replication or recombination.
