Scientists have discovered for the first time that bats carry influenza viruses in 2012, but they have just discovered that human beings can also search for them.
Animals, such as pigs and chickens, can contract the flu in a similar way to humans because there are similar receptors in the respiratory tract. Therefore, the birds and the pigs are very dangerous.
But viruses of the bovine fluid attach and between cells differently, compared to other viruses.
"A new alarming study found that cattle receptors are really similar to those of rats, pigs and chickens," said Mohamed Munir, a professor of molecular virology at the University of Lancaster.
Scientists at the University of Zurich, who published their research in Nature, identified the "future" portal that allows bovine viruses to enter the cells of the host to cause infection. Unfortunately, this future also exists in certain bovine cells.
Influenza viruses infect many cattle species by joining a molecule called sialic acid, found in the respiratory cells of these animals. Similar receptors are also present in the human respiratory tract, especially in the lungs, hence the spread of avian and swine flu to humans.
Scientists have found that bovine influenza viruses enter their host cells through cell surface proteins called MHC-II, which is concerned that these protein receptors are very similar among several species, including rats, pigs and chickens.
Scientists have studied genes to see if they are resistant or vulnerable to infection with bovine influenza. Initially identified 10 important genes, 5 of which are responsible for making proteins associated with MHC-II. They then used the genome-free technique to block MHC-II proteins from the cell, to find out that the bovine influenza infection could not enter the cells.
MHC-II proteins have been found on the surface of some immune cells and play an important role in binding body cells and pathogens, such as bacteria and viruses.
Due to the role of agricultural animals in transmitting influenza to humans, the BAT virus seems to have the ability to infect humans directly or infect other animals.
The bats transmit a series of other deadly diseases, which transport 65 species of human pathogens, including Ebola.
