Zombie ant fungus, meet the anti-zombie-ant fungus
A new study has found that a zombifying ant fungus can be kept at bay by another pathogen.
It turns out that it takes a fungus to control one.
Skip to next paragraphFor the first time, researchers have discovered how an ant colony can survive an onslaught of zombie-fungus, also known as Ophiocordyceps, a behavior altering, deadly parasite.
Ophiocordyceps enters an ant's brain, causing it to march to its death at a mass grave. Once the ant is dead, the fungus produces more infectious spores.
In their new study, David Hughes, an entomologist at Penn State and his team describe a hyperparasitic fungus ? that is, a parasitic fungus that exploits another parasitic fungus ? that helps ants to ward off a zombie epidemic.
"In a case where biology is stranger than fiction, the parasite of the zombie-ant fungus is itself a fungus," Hughes said in a statement.
Ants are the dominant creature of all land-based ecosystems. In tropical forests, for example, almost 70% of individual insects are ants. They provide ample opportunities for scientific investigation.
Previous research has shown that ants groom each other and themselves to defend their colonies against pathogens such as fungi.
Hughes and his group modeled ant behavior in order to see grooming's effect on restricting infection. They found that combined with the ant's own grooming practices, the hyperparasitic fungus significantly limited the spread of the deadly, zombifying Ophiocordyceps.
Many ants become infected with the Ophiocordyceps fungus because it grows slowly, producing immature spores for about a month after killing its host.
However, the likelihood of an individual ant becoming a zombie is relatively low because the young spores are susceptible to the hyperparasitic fungus.
"Because the hyperparasitic fungi prevents the infected zombie-ant fungus from spreading spores, fewer of the ants will become zombies," explained Hughes.
The new study is available online in PLoS ONE.

Live in London: Samsung Mobile Unpacked 2012!
Enough teasers. It's finally time to do this. We're at Earl's Court, London, for the Samsung Mobile Unpacked 2012 event. You might recall previous Unpacked events in which we saw the original Galaxy S, the Galaxy S II, the Galaxy Note, and now ...?
Look, we're all expecting to see the Samsung Galaxy S III. Or the Samsung Galaxy S3. Or Something with the name Galaxy. Or at the very least, something with the name Samsung in it.
Here's the best part: You get to be here with us for the entire unveiling. Need some deets?
- What: Samsung Mobile Unpacked 2012
- Where: London
- When: 1900 BST, 1400 EST, 1100 PST
- Official stream: Samsung's beaming this one worldwide, which is darn nice of them.
- Online chat: Doing a liveblog of something that's being broadcast live is sort of silly. So here's the plan. Join myself and Alex Dobie for a live chat from the event. (It's embedded after the break in this post.) We're not going to just tell you what's going on. You can see that for yourself in the stream. We're going to keep you up to date on everything you can't see in the stream. It's the least we can do.
- And much more: Presumably we're going to get some face time with whatever's announced, so check back early and often.
We'll see you back here this evening -- or this afternoon, or whatever time it is wherever you are -- for some hot smartphone action! In the meantime, be sure to hit up all the awesome Samsung Galaxy S III discussions in the forums!
