BATS : NUMEROUS - WIDE RANGING - and adapted to carrying diseases.

IN A 2018 PAPER IN : 'CELL HOST AND MICROBE', scientists in China and Singapore reported on their investigation into how BATS handle something called DNA sensing   

The energy demands of flight are so great that cells in the body break down and release bits of DNA  that are then floating around where they shouldn't be.

Mammals, including bats, have ways to identify and respond to such bits of DNA, which might  indicate an invasion of a disease-causing organism. But in Bats, they found, evolution has weakened the system, which would normally cause inflammation as it fought the viruses.

IF PREVIOUS OUTBREAKS OF CORONAVIRUS are any indication, the Wuhan strain that is now spreading may eventually be traced back to bats

Dr. Peter Daszak, president of Eco-Health Alliance, who has been working in China for 15 years studying, diseases that jump from animals to people, said, ''We don't know the source yet, but there's pretty strong evidence that this is a bat-origin coronavirus.''

He said, ''It's probably going to be the Chinese horseshoe bat,'' a common species that weighs up to an ounce.

If he's right, this strain will join many other viruses that bats carry. SARS and MERS epidemics were caused by bat coronoviruses, as was highly destructive viral epidemic in pigs.

One bat can host many different viruses without getting sick. They are the natural reservoir for  Marburg, Nipah and Hendra viruses, which have caused human disease and outbreaks in Africa, Malaysia, Bangladesh and Australia.

They are thought to be natural reservoir for the Ebola virus. They also carry the rabies virus, but in that case the bats are affected by the disease.

Their tolerance of viruses, which surpasses that of other mammals, is one of their many distinctive qualities. They are  the only flying mammals, they devour disease carrying insects by the ton, and they are essential in the pollination of many fruits, like bananas, avocados and mangoes.

They are also an incredibly diverse group, making up about a quarter of all mammalian species.

But their ability to coexist with viruses, than can spill over to other animals, in particular humans, can have devastating consequences when we eat them, trade them in livestock markets and invade their territory.

Learning how they carry and survive so many viruses has been a deep question for science, and new research suggests that the answer maybe in how the bats' evolutionary adaptation to fight changed their immune systems.
