several Hongkong poultry H6N1,H6N2 genomes from 2001-2003 were released.
e.g. A/Ck/HK/SF3/2001(H6N1)
It is similar in 7 segments to HK-flu from 1997, so apparantly reassorted
with H5N1 by exchanging HA.
Did this reassortment happen before the 1997 outbreak in Hongkong,
is it the reassortment which led to that outbreak ?
It seems so. E.g. the PB1 of SF3 is closer to A/Dk/HK/562/1979(H10N9),
the best matching PB1 from the 70s, than A/H//156/1997.
But I'm not so sure yet since we had these periods of low mutation
in China which can corrupt normal molecular-clock analyis.

Anyway, I think that probably there was H6N1 in HK poultry all the time
before 1997 and then it just picked up the HA from A/Gs/Gd/1996(H5N1),
so to form a strain much more virulent to chickens.

They should have deep-frozen some sick-chicken/duck-tissues from HK
from the 80s or 90s. We do have some HK-sequences from the 70s,
but almost nothing from 1980-1996.

The 2004 tree-parrows study shoud be redone.
Find the places,species in China where flu
survives without mutating.

Reassortment in 1997 isolates was described in 1997. You are a decade behind the literature.

AFAIK no precursor virus was found so far which matched the 1997 virus
in 7 segments so well.
It was assumed that several reassortments had happened in wild birds
and then had jumped from wild birds to poultry in 1997.
But now we see matching H6N1 poultry viruses from 2001,
possibly existing in this or similar forms before 1997.

However, this is only for the 1997 outbreak, which was controlled.
Later outbreaks did happen by other viruses.

4 Qinghai genomes from 2010 meanwhile at genbank with
236,233,250,229 diferences from the original
A/Gs/Index/Qinghai/2005(H1N1)

47 mutations per year fits well to what we saw in 2005-2007

3524 H5N1-HA only since 1997, Asian HP (genbank,2011/07/22)

http://magictour.free.fr/panflu/h5ha11a.GIF

I printed it on 8 normal sized paper-sheets
and glued it together
compare with the phylo-tree (link ?)

the lower 9 sequences are LP,
will be removed in the next version

Indo - splits in 3 areas (one of 40 just above the LP)
to be corrected

--------------------

biggest subpart (~30%) is "Qinghai" which starts in the middle
I count ~19 markers

Thailand,Vietnam,old 6 markers top

Thailand,Vietnam, 15 additional markers

Indonesia, 11 markers

Korea,Japan 2003 overlaps with Indo in the pic

2008ff Korea,Japan,Mongolia 12 markers above Qinghai

China 5 markers

lower part (below Qingha) : 4 markers


I'm planning to list all the markers and group more correctly

------------------------------

2nd version , no green for printing, Qinghai splits

new human H5N1 sequences from China, 2008-2010

looks like a lot of reassortment and mixing,
hard to track the evolution.

I don't see that _one_ new dominant strain
