  • origin of the Qinghai virus

    the Qinghai-strain is a reassortant of two Jiangxi-mallards


    ASM is a nonprofit professional society that publishes scientific journals and advances microbiology through advocacy, global health and diversity in STEM programs.

    Investigators formerly believed that in-fluenza viruses are transmitted unidirec-tionally from wild migratory birds to do-mestic species. However, the A/BHGoose/Qinghai/65/05 (H5N1) virus is a reassortant that obtain edits M,NS,PA,PB1, and PB2 gene segments from A/Mallardduck/Jiangxi/1653/05 (H5N1) and it’s HA, NA,and NP segments from A/Mallard duck/Jiangxi/2136/05 (H5N1). In both cases, domestic ducks infected mallards that were over-wintering in southern China.Thus, the A/BH Goose/Qinghai/65/05 (H5N1)virus apparently contains gene segments from influenza viruses in domestic birds, along with gene segments that were spread in part by mi-gratory birds. The A/BH Goose/Qinghai/65/05(H5N1) virus contains lysine at residue 627 ofPB2, which is associated with pathogenicity in mammals. Did the selection of the PB2 lysine 627 variant occur in mammals in China.

    Re: origin of the Qinghai virus

    In 2004 we had sequences

    A/peregrine falcon/Hong Kong/D0028/2004 ("falcon")
    A/Ck/ST/4231/2003 ("2003")

    they were 16,18,60,28,19,20,15,23 0/00 different in the 8 segments.
    So apparantly the PA-segment had been reassorted before.

    Now, until 2005 they had evolved to viruses similar to :

    A/Gs/Shantou/2216/2005 ("Shantou")
    A/migratory Dk/Jiangxi/2295/2005 ("Jiangxi")

    these steps involved
    11,11,09,11,08,13,07,12 0/00 differences for falcon-->Shantou
    14,06,02,14,07,10,02,08 0/00 differences for 2003 --> Jinagxi

    Shantou and Jiangxi were 18,21,68,35,25,26,14,33 0/00 apart.

    Then some bird was infected with 2 strains similar to
    Shantou and Jiangxi and reassorted to a virus similar to

    A/Bar-headed Gs/Qinghai/65/2005 ("Qinghai")

    which is
    09,05,09,36,25,28,02,06 0/00 apart from Shantou
    24,21,69,02,03,03,12,34 0/00 apart from Jiangxi

    and this virus proved very fit for intercontinental travel
    it spread to Qinghai-lake and probably independently
    to Novosibirsk and then through Russia and Turkey to Europe and Africa



    Code:
     /        falcon----------16,18,60,28,19,20,15,23----------2003           \
    |  11,11,09,11,08,13,07,12                        14,06,02,14,07,10,02,08  |
     \        Shantou---------18,21,68,35,25,26,14,33--------Jiangxi          /
      \            09,05,09,36,25,28,02,06     24,21,69,02,03,03,12,34       /
       16,10,12,32,18,22,05,13-----------Qinghai------22,22,65,14,13,12,14,28


    I just discovered 12 other full-genome sequences from Qinghai from lanl ,
    which are much different to the Qinghai genomes from genbank.
    31 genomes in total, checking now...
    A/bar-headed Gs/Qinghai/2/2005 is similar to the Jiangxi/2300 virus, but even more
    distant to the other Qinghai-viruses .
    Also many differences Shantou/2216 - Qinghai/65 also are differences Shantou-Qinghai/2
    I don't understand this yet...

      Re: origin of the Qinghai virus

      ahh, this was all known since Febr. 2006 , I just found this:



      the paper at the start of this thread was just a later summary !

        Re: origin of the Qinghai virus

        where/how were those Qinghai sequences collected
        which are so similar to the Qinghai virus outside China
        A/barheaded goose/Qinghai/65/2005 and similars ?

        This series of viruses /59../75 is rather uniform
        and different from the series /1,.../10
        from the Chen et.al paper.

        These latter viruses -public since a few months only by niman's intervention-
        are strange and different from what we see elsewhere.
        So different, that I wonder whether this is this some different
        kind of flu-evolution, whether there are frequent errors in the
        sequences or what is going on.


        I'm still trying to make sense of the Qinghai-lake sequences.
        This isn't normal, isn't what we usually see with related influenza sequences.

        Well, except these Qinghai-lake sequences at genbank, they behave well,
        and they are similar to the Qinghai sequences outside China.

        These are:
        A/bar-headed goose/Qinghai/0510/2005
        A/bar-headed goose/Qinghai/12/2005
        A/bar-headed goose/Qinghai/59/2005
        A/bar-headed goose/Qinghai/60/2005
        A/bar-headed goose/Qinghai/61/2005
        A/bar-headed goose/Qinghai/62/2005
        A/bar-headed goose/Qinghai/65/2005
        A/bar-headed goose/Qinghai/67/2005
        A/bar-headed goose/Qinghai/68/2005
        A/bar-headed goose/Qinghai/75/2005
        A/environment/Qinghai/31/2005
        A/brown-headed gull/Qinghai/3/2005
        A/black-headed gull/Qinghai/1/2005
        A/black-headed goose/Qinghai/1/2005
        A/black-headed goose/Qinghai/2/2005

        Let's exclude A/bar-headed goose/Qinghai/1A/2005 , where only HA and NA
        are available and which seem to behave well.

        Then we have A/great black-headed gull/Qinghai/1/2005
        which behaves well in segments 1,2,7,8 but shows some signs of
        rebellion in segments 4,5,6 and in a small part of segment 3.
        Still not as naughty as the other sequences below.

        Now, A/bar-headed goose/Qinghai/5/2005 behaves well in segments 2,4,5,6,7,8
        but entirely naughty in 1,3.

        A/ruddy shelduck/Qinghai/1/2005 behaves well in the first half of segment 1,
        and in the other segments, except possibly 3 polymorphisms in HA which are
        from the naughty sequences, and entirely
        naughty in the second half of segment 1, indicating recombination in segment 1.

        A/Qinghai/bar-headed goose/2/2005 is much different from everything else
        in segments 1,2,3,7,8 and just "only" naughty in segments 4,5,6.
        It's similar to A/migratory duck/Jiangxi/2300/2005 but still a bit more
        distant to the well behaving Qinghai-lake sequences than the Jingxi
        virus, which is assumed to have reassorted with A/migratory duck/Jiangxi/1653
        at Poyang lake in 2004 or early 2005 1700km west of Qinghai lake
        so to form the well behaving Qinghai sequences.

        2 is equal to 4 in segment 7 - another reassortment


        Now it remains this list of 11 naughty Qinghai-lake viruses:

        many common polymorphisms, but these are shared by varying
        groups of viruses, not constant fixed groups.
        not what we usually see
        frequent recombination ?
        frequent infections with different viruses, mixed samples ?
        due to the sandstorm ?
        many errors ?

          Re: origin of the Qinghai virus

          seems that all those viruses isolated at Qinghai lake have subsequently
          died without successors and what we see in Liaoning and outside
          China is from another ancestor.
          So it didn't fly from Qinghai to Mongolia and Siberia.
          It came from elsewhere. Qinghai-lake was just a sidestep of the virus,
          not important for and unrelated to its global spread.

            Thanks for linking to this. It was before my flubie days and I had never seen it.

            Now, 2 years later, how have your thoughts changed on all this (if they have)?

              Re: origin of the Qinghai virus

              I should look again at the Qinghai-lake sequences including upates...
              maybe later

              I remember we had one other recombination (/1a or /f ?)
              one year later, then some completely different sequences,
              not ancestors of 2005 and now some genes from the pikas
              while others are from earlier Chinese birds, not found in 2005
              at Qinghai-lake (?)

              the 4 Qinghai-lake markers in PB2 of well-behaving 59-75
              are still not seen elsewhere.

              We saw quite some strange mutations which turned out to be
              likely lab-errors in the meantime, I didn't know this in 2007.

              I'm a bit wondering whether these naughty sequences
              and also the pika sequences contain contaminations=errors.
              Maybe from the same Chinese lab in Qinghai

              there must be one thread with a list of later
              recombinations, reassortments in the Qinghai virus
              (e.g. Kurgan , Nigeria , Crimea )
              but these were few as compared to Qinghai-lake 2005

              the virus evolved rather constant (except Hungary/Sussex)
              with a mutation rate of
              45 mutations per genome per year.
              This is not necessarily seen in other Chinese H5N1 where we
              have periods of lower mutation rates.

              Few recent Qinghai genomes (2008,2009), so I'm not sure
              how it continued the last 2 years

                It came from elsewhere. Qinghai-lake was just a sidestep of the virus,
                I've seen the explanation that the virus just suddenly changed and went virulent, which never quite makes sense to me. Do you still think what you said in the quote or has there been evidence to the contrary?

                  Re: origin of the Qinghai virus

                  well, almost all of the (~20) viruses which had been sampled from
                  Qinghai-lake in 2005 had the 4 markers in PB2 which were never seen elsewhere.

                  There could have been H5N1 in/near Qinghai lake in 2005
                  which qualifies as ancestor of the African,European viruses
                  but which was not sampled.
                  But then, that ancestor could have been elsewhere as well.

                  We know that Qinghai had many viruses and reassortment,
                  (recombination ?) in 2005 and that there was early H5N1,
                  although the one from Siberia,Europe,Africa. was not found.
                  But if one H5N1 can go to Qinghai-lake then another one
                  might have too ?!

                  The pikas near Qinghai-lake had not the virus from 2005,
                  but a new one from Korea,Nigeria with mutations that
                  were aquired elsewhere, not in Qinghai lake.
                  They got imported virus-parts
