Vaccinating vampire bats towards rabies may also help stop the unfold of the illness to livestock and people. NPR’s Scott Simon talks with epidemiologist Tonie Rocke a couple of new technique to vaccinate bats.
SCOTT SIMON, HOST:
Vampire bats could have earned their identify, because the Smithsonian Channel describes them…
(SOUNDBITE OF ARCHIVED RECORDING)
UNIDENTIFIED COMMENTATOR: Vampire bats are the one bats on the earth that feed on blood.
SIMON: Oh, my. Nicely, if that is not sinister sufficient, the illnesses these bats carry, like rabies, can kill livestock and even people. The bats have precipitated rabies outbreaks throughout their vary from Mexico to Argentina, however a brand new research exhibits promise in a brand new methodology to attempt to vaccinate the animals, and it depends on a much less scary a part of vampire bat habits. They’re recognized to groom one another. Tonie Rocke led the analysis crew. She’s an epidemiologist with the U.S. Geological Survey’s Nationwide Wildlife Well being Heart and joins us now for Madison, Wisconsin. Thanks very a lot for being with us.
TONIE ROCKE: I am pleased to be right here. Thanks for having me.
SIMON: They groom one another?
ROCKE: Oh, sure, one another and themselves lots, on a regular basis. It is habits that we will benefit from in making use of medicines – and vaccines, specifically.
SIMON: Nicely, inform us how that works.
ROCKE: Nicely, so at the moment, the way in which to handle rabies depends on one thing known as a vampiricide. It is really a poison that is utilized topically. The bats are launched, they usually return to their colony, they usually groom one another, eat the poison, they usually die. However sadly, this method can generally exacerbate rabies as a result of it causes the bats to disperse. As soon as bats begin dying of their colony, they will disperse and carry the rabies with them. So we’re searching for a special method. We would use the identical form of methodology. We would apply a vaccine topically, launch the bats, after which they go once more and lick one another and switch vaccine as a substitute of poison.
SIMON: (Laughter) That is going to sound awfully naive, however – what? – you prepare them? I imply, what…
ROCKE: No. There isn’t any coaching them. We entice them, seize them, apply the fabric, they usually simply naturally return to their colonies. They usually need to get the fabric off of them as quickly as they’ll. So that they return. All of them lick one another and themselves, they usually eat the fabric.
SIMON: And forgive me if this sounds insensitive, however why ought to we care concerning the survival of vampire bats?
ROCKE: It is not a lot the survival of vampire bats that we’re nervous about. We’re nervous about transmission of rabies to cattle and to people. And so if we vaccinate them, it improves their survival barely, however extra importantly, it stops transmission of the virus.
SIMON: Now, I collect that is what we name a preprint research as a result of you have not been peer reviewed but. However are you able to inform us the place your work goes from right here?
ROCKE: Positive. So this research, specifically, was actually describing the medium that we’ll use to use the vaccine to the bats in. We have needed to work on that a short while to verify it is the correct consistency, that it transfers to bats, that they’re going to eat it.
SIMON: I’ve to ask. Once you discuss guaranteeing that the bats will eat it, I imply, does this imply developing with a pleasant taste?
ROCKE: No. They simply need to get it off of them. So it interferes with their flight and every part. So that they’ll lick something, actually, that you just placed on them. It is not – in all probability would not style superb, to be sincere.
SIMON: And what do you see as among the implications of this research, if what you consider you’ve got found is borne out?
ROCKE: Nicely, for one, this may very well be used to handle different illnesses in bats, specifically, different zoonotic illnesses that have an effect on individuals.
SIMON: Nicely, the implications of this for different species additionally have been fairly good, aren’t they?
ROCKE: Sure, as a result of they transmit illnesses to a number of different species, actually rabies to different wildlife, however notably livestock in Latin America.
SIMON: Analysis epidemiologist Tonie Rocke, who’s with the U.S. Geological Survey. Thanks a lot for being with us.
ROCKE: You are welcome. My pleasure.
