The horse influenza viruses evolved
from avian influenza viruses, and the recent appearance of clinically significant canine influenza apparently resulted from a mutation of the equine H3N8 virus.
This protein can protect cultured human cells
from avian influenza viruses but is ineffective against strains that have acquired the ability to infect humans.

avian and swine
viruses from North America, a swine flu strain usually seen in Asia, and a human
influenza strain.
It is a mixed - origin

avian influenza virus more transmissible between mammals.
They exposed plasma

avian influenza virus H3, H4, H5, H6, H7, H8 and H12 subtypes using two laboratory tests to see how many different
viruses participants reacted to, and how strongly.
Avian flu (also «bird flu», «avian influenza», «bird influenza»), means «flu from viruses adapted to birds», but is sometimes mistakenly used to refer to both other flu subsets (such as H5N1 flu) or the viruses that cause them (such as H

avian influenza, West Nile
virus, SARS, and even Ebola — originated
from animals.

avian influenza viruses circulating in domestic ducks and chickens, Guan's group reported in 2013.

avian - like glycan receptors (yellow spheres) to the 2013 H7N9
influenza virus hemagglutinin (in ribbon diagram).
He likens the
virus to
avian influenza, which humans can contract
from birds but which is so poorly transmissible between people that it hasn't triggered an epidemic.
But Tompkins warns that repeated vaccinations with distinct hemagglutinins would probably be needed to protect birds
from the many strains of
avian influenza virus.
Three Emory scientists have signed a letter published last week in Nature and Science outlining proposed research on the H7N9
avian influenza virus. A strain of H7N9 transmitted
from poultry to humans was responsible for 43 deaths in China earlier this year, but so far, evidence shows that the
virus does not transmit easily
from human to human.

from exposure to sick cats, and there have been no outbreaks of AI among domestic cat populations.»

virus likely arose through the direct transfer of an
avian influenza virus — possibly
from among
viruses circulating in live bird markets — to dogs.
The H3N2 was initially identified in dogs in Asia, and it is suspected that it was transferred
from birds carrying the
avian influenza virus.
