Bats have a pretty bad report , which is not surprising deal the number of pathogens they conduct that can taint humans . Rabies , Nipah , Hendra , Ebola and Marburg are all virus carry by bat that can cause serious disease in humans . Marburg computer virus and some strains of Ebola computer virus can kill up to 80 - 90 % of humans infected . Furthermore , most of these are emerging disease that have rudely burst onto the scene over the retiring 50 years ( although somearguethey have been around a lot longer , but were n’t diagnose ) . But what is cause this raise in viral disease ? It turn out that it is just as much their mistake as it is ours .
human being have started creep into chiropteran territory , peculiarly in the tropics , which has lead to an increased hazard of impinging with these animals . For example , in Malaysia , commercial-grade slob farms were install in bat inhabit woodland which consequently led to the first human outbreak of Nipah , via pigs .
However , it seems that bats also gestate more human pathogens than other animals . Why is this ? squash racquet care to live closely to one another , snuggle up as they perch , giving plenty of opportunity for pathogens to spread between the bats .
So why do n’t these nasty viruses bolt down off the at-bat ? Scientists opine it ’s actually thanks to their power to fly . escape is enormously costly energy wise , and when a lot of vigour is used a circumstances of waste is accordingly produce . To prevent this reactive thriftlessness from damage the bats ’ desoxyribonucleic acid , bat have evolved advanced defence mechanisms that conveniently also help to foreclose the bats from succumb to disease .
Now you may be thinking- how do the viruses survive in the chiropteran , then ? Once again it ’s back to flight . Viruses are entirely pendant on the innkeeper to replicate , unlike bacterium , and therefore they require quite specific stipulation . When bats vanish , their internal temperature are rage up to around 40oC ( 104oF ) , which is too hot for many virus . This will wipe out off a quite a little of the virus in the bat , go away only those intrepid virus that have evolved tolerance mechanisms . Unfortunately for us , this also means they can tolerate a burning human fever .
But do n’t go hating on bats because of this- they ’re incredibly of import pollinators and they also eat mosquito . You succeed some , you lose some .
