Vampire bats now have taste for human blood

The discovery was made by Enrico Bernard and colleagues from the Federal University of Pernambuco who analyzed samples of scat to determine what the bats had been eating.Normally vampire bats are only able to process the fat of bird blood and will rather starve than attempt to feast on the high-protein blood of mammals.

The change is a significant concern as vampire bats are responsible for the spread of rabies in the region and if they are starting to attack humans then it could lead to new outbreaks.

"They are adapting to their environment and exploiting the new resources," said Bernard.
