In article there is a speech about a virus of bird flu of N5Sh striking not only easy, but also other human organs, including a brain, a liver, blood cells. The virus also passes through a placenta that can lead to pre-natal infection of a fruit.
Scientists: Bird flu can catch in a womb of mother on October 3 2007, 01:35
The virus of bird flu of H5N1 strikes not only lungs, but also other human organs, including a brain, a liver and blood cells. Besides, the virus passes through a placenta that can lead to pre-natal infection of a fruit.
Such conclusions were made by scientists of the Colombian university of New York and specialists of the Beijing university after studying of samples of fabrics of the people who were lost from bird flu. At the disposal of the head of research Jan Lipkin and his colleagues there were fabrics of the people living in China – the 35-year-old man and the 24-year-old expectant mother.
The carried-out analyses showed presence of a genetic material of a virus at lungs, a brain, a placenta, small intestines, and also at immune cages at blood and a liver. The four-months fruit which was lost together with mother, also was infected with bird flu, researchers reported.
Besides, scientists found out that the virus H5N1 is capable to oppress immunity and at the same time to cause hyper stimulation of immune system. On the one hand, the virus damages cages of immune system, in particular, makrofagi. During too time, it causes "a tsitokinovy storm" – too strong reaction of immune system to virus introduction.
"We found out that the volume of damages doesn’t correspond to quantity of the infected cages. It confirms a hypothesis that exists also an indirect way of negative impact of a virus" – Lipkin reported.
The virus of bird flu strikes mainly birds, but also is capable to cause a disease in the person. According to World Health Organization, since 2003 328 people caught bird flu, from them 200 – were lost. The new data received by scientists, help to explain high frequency of deadly outcomes at infection with a virus.
