SCOTT SIMON, HOST:

Vampire bats might have earned their title, 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 induced rabies outbreaks throughout their vary from Mexico to Argentina, however a brand new research reveals promise in a brand new methodology to try to vaccinate the animals, and it depends on a much less scary a part of vampire bat conduct. They’re identified to groom one another. Tonie Rocke led the analysis group. 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 quite a bit, on a regular basis. It is conduct that we will reap the benefits of in making use of medicines – and vaccines, specifically.

SIMON: Nicely, inform us how that works.

ROCKE: Nicely, so presently, the way in which to handle rabies depends on one thing referred to as a vampiricide. It is truly a poison that is utilized topically. The bats are launched, and so they return to their colony, and so they groom one another, eat the poison, and so they die. However sadly, this strategy can typically exacerbate rabies as a result of it causes the bats to disperse. As soon as bats begin dying of their colony, they’re going to disperse and carry the rabies with them. So we’re on the lookout for a distinct strategy. We might use the identical form of methodology. We might 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 practice them? I imply, what…

ROCKE: No. There is no coaching them. We lure them, seize them, apply the fabric, and so they simply naturally return to their colonies. And so they need to get the fabric off of them as quickly as they will. So that they return. All of them lick one another and themselves, and so they eat the fabric.

SIMON: And forgive me if this sounds insensitive, however why ought to we care in regards to the survival of vampire bats?

ROCKE: It isn’t a lot the survival of vampire bats that we’re fearful about. We’re fearful 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: Certain. 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 suitable consistency, that it transfers to bats, that they’re going to eat it.

SIMON: I’ve to ask. If you speak about ensuring that the bats will eat it, I imply, does this imply arising with a pleasant taste?

ROCKE: No. They only need to get it off of them. So it interferes with their flight and the whole lot. So that they’ll lick something, actually, that you simply placed on them. It isn’t – in all probability would not style superb, to be sincere.

SIMON: And what do you see as a few of the implications of this research, if what you imagine you’ve got found is borne out?

ROCKE: Nicely, for one, this could possibly be used to handle different illnesses in bats, specifically, different zoonotic illnesses that have an effect on folks.

SIMON: Nicely, the implications of this for different species additionally had been fairly good, aren’t they?

ROCKE: Sure, as a result of they transmit illnesses to a lot of different species, definitely rabies to different wildlife, however significantly 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.
