  • New Flu Virus Found in Peruvian Bats

    previous thread abouts Guatemala bat-flu here:


    we identified a novel influenza A virus, designated as H18N11,
    in a flat-faced fruit bat (Artibeus planirostris) from Peru

    GenBank accession
    numbers CY125942-CY125949), and this virus was designated A/
    flat-faced bat/Peru/033/2010 (A/bat/Peru/10) (Table S1).

    We sampled 114 Peruvian bats captured during 2010 in
    Truenococha and Santa Marta

    not yet at genbank:

    they knew it since 2010, but didn't talk about it. I guess, it's because if the
    current system of funding,grants,journals
    they want to have it exclusively and they don't want others working
    on it, or talking/speculating about it, before they publish their paper (?)
    The Guatemala paper was published in Feb.2012

    [ it might take 3 years before they tell us, when there was a (failed) bioterrorist
    attack or lab accident using a new manmade virus ?!?
    or just when someone succeeded to make/reassort a new flu-virus of real pandemic potential ]

    this is likely all random and doesn't show a more recent common ancester with one of the known
    virus-segments than with another one
    except maybe the 17g in segment 2 (and H9N2 in segment 5 ?)

    the Peru bat-virus has much higer AT-scores in all segments than the Guatemala bat
    --> more mammalean-like, less avian:

    6316,6393,6479,6208,5702,5814,5740,5936, = 6152(13098)   >A/flat-faced bat/Peru/033/2010(H18N11)

    this is even higher than the equine H7N7 and influenza B !!
    Only flu-C has higher AT-score
    so there is maybe either a big difference in the methylation
    capabilities of these 2 bat-species, or there is a mammalean reservoir
    in Peru that feeds the bats with flu

    someone please test the alpacas and llamas
    ----------edit--------------- better piccaries and tapirs

    the common ancester of the Peru and Guatemala bat viruses could have "lived" ~150-200 years ago,
    except segments 4,6 , assuming the same mutation rate as in humans,swine,horses

    since the date of the most recent common ancester of the bat and any other known flu-A segment
    is before the date of the most recent common ancester of any two other flu-As (same segment),
    the phylo-distance to all known contemporary flu-A segments must be the same.

    Any differences can be due to periods of slow evolution or lack of amino-acid mutations
    in inner segments of mallard-flu or other such constraints or are just random.

    Re: PNAS: A distinct lineage of influenza A virus from bats

    I posted a comment about it at plospathogens:

    ahh, sessionid, so the link will likely vanish
    and click on comments

    ------ no reply -------

    of the nucleotides are from {A,T}.
    For the Guatemala bat-virus it was only
    which was more similar to the usual value in birds.
    61.52% is very high, it's high in all 8 segments,
    and higher than in any human or swine flu virus,
    even higher than in the extinct equine H7N7 or in flu-B -
    only flu-C has a higher proportion of A,T nucleotides.
    It is supposed to happen by RNA-methylation and
    indicates another mammalean reservoir (equine ?),
    where it evolves. I am posting about it here :

      New Flu Virus Found in Peruvian Bats


      New Flu Virus Found in Peruvian Bats
      Rachael Rettner, Senior Writer | October 23, 2013 11:02am ET

      A brand new flu virus has been found in Peruvian bats, according to a new study from researchers at the Centers for Disease Control and Prevention.

      The virus, called A/bat/Peru/10, belongs to a family of flu viruses known as influenza A, which mainly infect birds, but can also infect other animals, including people...

        Re: New Flu Virus Found in Peruvian Bats

        btw. I also sent emails to Adriano Bravo and Simon J Ghanem
        who (co-) authored papers about bats meeting at Collpas
        in Amazon rainforest.
        Speculating that they transmit flu that way
        and maybe smell the Collpas, visited by tapirs and piccaries ("skunk pigs")

        also emails with mixin

        interesting bat videos at youtube (link)

        another idea, how bats maybe find the Collpas at night:

        nice videos, how they catch insects, raise babies

        more support for the speculation that the batflu in Peru (but not the one in Guatemala)
        evolves in "higher organisms" (= peccaries,tapirs ?) and not bats

        this could also be relevant to rabies research, occasinally in Brazil rabies was found in fruit bats,

          New Flu Virus, 'A/bat/Peru/10,' Found In Peruvian Bats

          Tests done by the researchers so far suggest the virus is not an immediate concern for people, said study researcher Ruben Donis, associate director of Policy, Evaluation and Preparedness at the CDC’s Influenza Division. The researchers have not been able to grow the virus in human or primate cells, or by other methods, which is characteristic of viruses that do not infect humans, Donis said. The virus may have very specific requirements for growth, for instance it may only be able to replicate in the intestinal cells of bats, he said.

          On the other hand, the researchers do not have enough information to say for sure that the new flu virus cannot eventually infect people, Donis said.

          Last year, the same group of researchers identified a distinct influenza A virus, H17N10, in fruit bats living in Guatemala.

              We modified the bat virus sequences in order to rescue it. Soon you will
