MADRID, 24 Jul. (IRIN) -
Bats are the main transmitters of the virus family 'Paramyxoviridae' that causes measles, mumps, pneumonia, influenza and encephalitis in humans, Carr?'s disease in dogs and plague in small ruminants .
In an international study conducted in collaboration with researchers from the IRD and published in the journal Nature communications', identified more than 60 new species of these infectious agents that affect all animals, including humans. So, thanks to global sampling, research has shown that these viruses come from bats.
Virologists animals gathered about 10,000 samples, of which about 90 species of bats from Africa, Latin America, Asia and Europe. Through blood and organs, they observed a high genetic diversity of paramyxovirus in these small mammals, suggesting that these infectious agents had time to evolve largely in bats throughout history.
In addition, the scientists found in all known species of bats worldwide, demonstrating that there was a spread from continent to continent from a common ancestor and that these guests are carriers flying for several millennia.
Finally, biologists found in the bodies of bats almost every genre of the paramyxovirus family, which is not true in other animals. Therefore, such a representation viral confirms that, no doubt, bats are the source of the infection throughout the animal kingdom.
As proof, the researchers tested the probability of each gender - bats, rodents, birds, humans, dogs or cattle - has been the source of infection. According to the phylogeny of the paramyxoviruses, the probability of transfer from bats to other animals is the strongest.
ALWAYS THREAT PLAN
Moreover, the researchers also found that currently the bats could be the reservoir of some paramyxovirus believed characteristic of humans. In fact, scientists showed in these small animals paramyxovirus species genetically similar to those seen in man, and these could infect again.
Childhood diseases such as measles or mumps, considered by the World Health Organization (WHO) as almost eradicated in developed countries, could reemerge. However, the hypothesis of an eradication excludes possible, in fact, the presence of any animal reservoir.
Also, another conclusion from this study is the discovery of some extremely dangerous virus in regions of the world where there is suspected. It is, for example, Hendra and Nipah virus, two newly emerging pathogens that caused fatal encephalitis epidemics in Asia and Australia. Currently there have been no human cases in other parts of the world.
However, the researchers identified in the bodies of African bats. In Gabon and Ghana, where he conducted the study, the two infectious agents are strongly present, so it is feared a possible emergency in the continent.
