Lethality of a virus of "Spaniard" have bound to three genes

Yoshihiro Kawaoka from University of Wisconsin (USA) and its colleagues from Universities of Kobe and Tokyo made experiments on polecats as mechanisms of development of a flu at these animals and at the person are close. Polecats infested with modern strains of a virus   order pyridium  of the flu which separate genes have been changed by a genetical stuff of the originator of "Spaniard".
The majority of the combined viruses invoked a lesion of the top respiratory tracts - oral cavities, a nose and the pharynx, typical for "usual" viruses of a flu. The virus carrying a certain combination from three genes of the originator of "Spaniard" became a unique exception. Thanks to this combination of genes, the virus has found ability to inpour into cells of lungs, and also to develop the RNK-POLYMERASE - the buy phentermine pharmacy enzyme, necessary a virus for its reproduction.
"Spaniard", or the virus of flu H1N1 raging in 1918, has led to development of the most terrible in modern history of mankind of a pandemic. Victims of a virus of a steel about 50 million persons all world. Unlike usual viruses of a flu, "Spaniard" amazed not only the top respiratory tracts, but also lungs. The serious pneumonia accompanied by massive hemorrhages, became a cause of death of many patients, experts consider.
The data received by the Japanese and American scientists, can be used for definition of potential factors of virulence at new pandemic strains of a virus of a flu. The dangerous buy levitra mastercard combination besides, described by them from three genes can become a potential target for medicinal preparations, considers Kawaoka .
The entire account about a findings of investigation has been published in magazine Proceedings of the National Academy of Sciences.
