Denmark: New influenza virus in mink created by re-assortment of human and swine influenza virus
that Nova Scotia mink had the triple-reassortant swine flu strain,
which isn't seen in Europe.
Maybe the mink is occupying a niche similar to pika.
I'd like to see similar tests done on marmots.
Perhaps these small mammals are far more important in influenza evolution than what we suspected.

Novel influenza virus detected 09.11.2009 While mass vaccination will reduce the swine flu, influenza is the next generation already in the starting blocks. Recently, a novel pathogen was discovered in Danish mink farm. So far, there is no evidence of transmission to humans.
The next influenza is determined: A few years ago, the bird flu caused a great excitement, the leap to humans, but they succeeded only in individual cases. The so-called swine flu were successful, around 6500 people across the world have it so far fallen victim. That said, the European center for the prevention and control diseases on Monday. Now in Danish mink farm was a novel virus have been detected with genes from both human and animal pathogens. A survey of employees revealed, according to World Health Organization (WHO), no evidence that the disease was transmitted to humans. The incident, experts said, but show "the constant evolution of influenza viruses, the potential for unexpected changes and the need for continuing vigilance, even in animals."
People become infected turkeys
They see this latest development further evidence that conduct "of influenza A viruses of animals and humans as a pool of genes between different hosts and herwandern. Moreover, the possibility exists "that a new influenza viruses in animals other than pigs might arise."
In support of the WHO calls the fact that H1N1, the new, so-called swine flu now even from humans to turkeys, for example in Chile and Canada, has been transferred or pets in the U.S.. The WHO is therefore a strict control and close collaboration between the health of humans and animals which urgently needed.
So far had the H1N1 swine influenza virus or not changed into a more dangerous form, shared with the WHO, so that the currently available vaccines offer good protection. Recorded to monitor potential changes in the H1N1 virus is also possible infections of animals that were both mammals and birds, and humans and investigated.
"Virus-mixer": experts fear could be a new virus variants in pigs are a traditional focus of observation thus formed pigs, because they are both viruses of humans can be infected as well as birds. You could, according to WHO as a sort of viral "mixer" is intended for the exchange of genetic material, where an animal is simultaneously infected with various viruses.
As an "ideal mixing vessel" for influenza viruses called Elke Reinking by the Friedrich Loeffler Institute for Animal Health on the Baltic island Riem pigs. 'Keeper with the flu should not be possible to go into the stalls, "she says. A transmission of the virus from humans to animals should be urgently avoided, the chance that there will be a mixture of viruses is minimized.
No risk of eating infected meat
In fact, since the outbreak of the global epidemic of swine flu in humans, a small number of infections of pigs observed with the virus, according to WHO, probably triggered by infected humans.
So far, however, such infections would have had no impact on the pandemic, which spread from person to person. With the further spread of the disease among humans, it is likely According to experts, however, that such transfers occur more frequently. Eat a danger to humans, the meat of infected animals, according to WHO, there is not adequate for preparation. The virus is killed during cooking or Fry.
Bird flu, which caused great concern a few years ago, according to the WHO, although still widespread, especially in Asia. The leap to humans, however, succeed in the pathogen H5N1 usually only when close contact with infected animals. Since 2003, the World Health Organization has recorded 262 deaths among men, twelve in this year.http://www.ftd.de/wissen/mensch/:exp...5.html?src=rss
Re: Denmark: New influenza virus in mink created by re-assortment of human and swine influenza virus
4,6 from human H3N2(2005)
1,2,3,5,7,8 from Euro-swine H1N1(2003)
Pig lungs and larynx are fed to minks.
Also to American turkeys or other pigs ?
What's the food for Mexican pigs , North-American pigs ?
(presumably they won't tell us if lungs or larynx would be fed)
Maybe a mexican pig with triple-reassortant --> H1N1 got imported food-meal
from Europe or Asia which contained lungs or larynx from European pigs ...
keywords for searchengine ?
"imported hogwash" seems to have another meaning
keywords in Spanish ? bazofia importada , forraje del cerdo
or imported,used,not disinfected swine-slaughtering or meat processing machines
from Asia - could be just special knives or saws.
It would be interesting to see Granjas Carroll's / Smithfield's list of Asian imports
from the last years

Re: Denmark: New influenza virus in mink created by re-assortment of human and swine influenza virus
My understanding after reading the report in post #20, is that the agent involved is an H3N2 virus, where the H and N genes are from human H3N2 flu, but the other six genes are from the triple-reassortment H1N1 swine flu (which is NOT the pandemic virus).
That is a really bad occurrence, as that could have caused another pandemic. Fortunately, there is no evidence that this reassorted virus can or has infected humans yet.
So we think the other six genes came from conventional swine H1N1? Or are you saying they came from the triple-reassortment virus despite the fact that seems impossible?
i think they probably came from European swine, which went
from birds to swine in ~1978 with all 8 segments.
the HA and NA from human H3N2 also happened in European
swine, it went from humans to swine quite early <1984
so the mink could have got the whole H3N2 from a swine
and the reassortment would be 25 years ago.
But this is speculation, the sequences are not public (yet)
But it is consistent - we haven't been checking swine sequences that throughly before this year, so such a virus could have existed in swine for 25 years and not been detected. And the lack of spread from minks to humans now is consistent with the lack of spread from swine to humans over the past 25 years.
Re: Denmark: New influenza virus in mink created by re-assortment of human and swine influenza virus
it had been detected.
While most swine-flu in Europe was the 1978-H1N1,
there were several swine with H3N2
and they had the HA and NA which went from humans
to swine ~25 years ago
I think, a flu in mink is unusual and would probably have been detected
before, pandemic or not.
Alarm and surveillance was even higher in 2006-7 than now.
Or in 2003 after the Dutch outbreak or 1999 in Italy.
