They fly with flue, don t they?

 Till today a flu keeping a one from a not opened secret a nature, despite  on virus, his caused , selected on 1933. And not ability to put are hope obstacles on the way, a flu epidemic.

A one from a reason is unique ability to agent of this infection to variability. In structure for genome virus of flu/genetically carrier enter are 8 isolated genes, and on that time  as genetical material of many other viruses is not fragmented. That allowing for flu viruses changing with separate genes, in result of which forming hybrids, or recombinants, having a new effect. Virus ologists predisposing  ,that new virus of flu a human and animals and wild birds by a way recombinations, and how explain it a science?

Scientists swept an interesting pattern, all viruses of flu variants causing are epidemics, had a different level for kinship with birds viruses or mammals.

And new wave for virus flue displaying is usually preceding for circulation between birds and other animals viruses, and genes, which are later entertained viruses structures, responsible for epidemics  through humans. And  till 5 years to displaying Hong Kong virus are selected viruses from ducks, same with Hong Kong by a one from a surface antigen. Viruses, deterred epidemic on 1977 autumn by a raw effects are same viruses, found by Soviet researchers within 2 years in whales, are living in shores in Antarctic, but a few genes of whale s are same with virus flu birds . And   these bases to think, that whales infected a flue eaten zooplankton which in viruses entered from Guano/excrements from birds and contains theirs goitres. A many quantities in guanos finding in oceans ,where are having bird s markets. But flu having not just birds, but are farm animals as pigs, cows horses, and recently found viruses of flue from North deer and from bats, and a most quantities viruses different variants for flu circulating through wild birds.Let s  compare:We are knowing 4 viruses, causing flu in a human, and more 50 viruses, spreading through birds, and it's a despite on, that human s virus flue studying 40 years, and active researching viruses are on the latest ten years begun. These bases are flue supplier are birds  in human and animals.

Flu in birds is not infection respiratory, but enterovirus, that infecting by dropsy way, and through water, meal. Different flu here displaying, just a few are hard with CNS damaging, till paralyses, birds are dead, in other disease displaying by type an acute bowel infection, in third are cough, sneezing having. Such different clinical pictures of diseases, is due, that between theirs, in difference from humans , where epidemy causing one virus, are circulating at the same time a few different viruses of flu. They are staying progenitors for new viruses.

A few birds are viruses carriers, are externally healthy, that meaning about a latest relationships viruses of flu with bird s organism, that they are adapted to each other.

How flu virus entering to birds?A right answer not having, maybe from other animals, or human.

Entered in organism for birds, flue viruses keeping , not changing, long years, like in piggy banks, when living between humans are faster changing effects.

Explaining that a life for birds continuation is shorter, and not keeping up working mechanism for population/massive/ immunity, which allowing viruses changing, as in human happening with viruses flu, and agents for epidemic through humans is overcoming a manufactured to him and  for many sicked immunity, And overcoming to hard conditions, virus is changing, In  result for anti gene drift  is a process for changing viruses of flu, where is happening selections mutants under affecting immunity - happening  are antigen transforming for viruses. And transforming here are partially, in difference from recombination, generating are new viruses variants. Between birds are having a full species for non-immune , in theirs organism viruses finding an awesome condition for staying, stocking and future spreading. Receives dates by virus ecology,  flue, is putting before researchers are new importance goals. If  we are virus ologists, select maximal quantities circulating in nature viruses, or if we are stocking with gene foundation for viruses flu, that helping on a case for epidemic on short date for doctors to arm with vaccination against virus fault. This is hope and effective vaccination with fighting insidious enemy. And also learning for viruses flu stats,  we can to understand laws for changing theirs antigen effects, and importance to learn theirs prognosing  and thus in advance ready to worthy meet with opponent.
