Discover bats that suck even human blood to live in Brazil

Blood-sucking bats are common, but bats sucking on human blood are a big deal.

We still hear that bats eat fruits mainly and even if they suck blood, they will only drink a little bit of animal blood. But the unusual thing happened, when horror stories from stories and movies came to life.

This bat is not born to survive with mammalian blood.

Researchers have found a hairy bat species in northeastern Brazil that draws human blood at night. Indeed this news is a bit of a shame for us to have this winged rat . "We are extremely surprised by this discovery," said Enrico Bernard from Federal University of Pernambuco. "This bat is not born to survive with mammalian blood."

Blood sucking bats have 3 types all and are native animals of the Americas, usually they only suck on domesticated domesticated animals such as cows, horses or pigs. They have sucked mammalian blood, but rarely attack humans.

Diphylla ecaudate bat Diphylla ecaudate and a white-winged bats named Diamus youngi are mainly hunting birds, most of them hunt chickens. That much is enough evidence for us to be assured of not being attacked by this bat.

Besides, the use of mammalian blood to survive is also very unlikely. Yet scientists have discovered these strange bats have changed their predatory behavior and nutritional behavior.

Bats suck blood from hairy legs.

The study report states that:

"The blood content of mammals and bird breeds is different, mostly in the nutritional composition. For example, bird blood has more water and fat and mammal blood is more dry and essential. is protein.

The study of eating behavior of blood-sucking bats D. rotundus suggests that they have biological properties that help them process proteins better. On the other hand, blood-sucking bats that use blood birds such as D. youngi or D. ecaudata have biological properties that make it easier for them to treat blood fats. "

Previous experiments have shown that when only pigs and goats appear in the feeding area of ​​the winged vampire bat, many bats choose to fast instead of changing their diets. , and sometimes wish to starve to death. Better to starve to death, not to abandon my eating habits.

But when the research team tracked the blood-sucking bat at Caatinga forest in northeastern Brazil, they found the strange event.

Caatinga forest.

Of the 15 fecal samples of this bat, besides the bird's DNA found, scientists also found three fecal samples containing both bird and human DNA - that is evidence of bats used human blood to live.

Besides, a remarkable point is that the indiscriminate deforestation here has caused the favorite prey of this bat to move a lot. That is probably the reason why the other hairy bat species are hungry and have to turn to another alternative blood source. Chickens can also be an option, if they are released regularly but often today, people often raise chickens in sheltered areas.

Many reasons can make this bat change its eating behavior, besides, we have other questions as to why they can handle large amounts of protein in human blood. Could this bat have evolved to survive?

Another dilemma: Will humans be affected by these blood-sucking bats?

The answer is probably. In the past, there were bats carrying hanta viruses that caused lung syndrome, transmitted by humans mainly by rodents and this disease is potentially fatal. A little bat, how much blood will it attract? Not to worry about that, we should worry about the diseases that the bite could bring.
