Parasites That Can Control Insect Minds

Ant writes to tell us that NewScientist is running an article about an interesting parasite that apparently has the power to 'brainwash' its host. From the article: "The parasitic Nematomorph hairworm (Spinochordodes tellinii) develops inside land-dwelling grasshoppers and crickets until the time comes for the worm to transform into an aquatic adult. Somehow mature hairworms brainwash their hosts into behaving in way they never usually would - causing them to seek out and plunge into water."

      There's that parasite that's found in cat faeces, that when ingested by a rat, will cause a rat to become reckless and unafraid of cat smells (previously running a mile) so that it will likely be killed, infect the cat responsible and carry on the cycle.
      It also makes humans who ingest it more wreckless and therefore likely to get killed - and provide the opportunity for their infected corpses to be consumed by another potential host.

      The thread worm (?) in Africa - the one that can come out anywhere on the body, not through stools - for example the leg, or eye or wherever - is passed on through drinking parasite infested water. At the time of emergence, it will make its host, just as likely a human as any other animal, attracted to water, and they will wander to the water, immerse themselves in it, the parasite will emerge and infect the water.

      Parasites altering their host's behaviour is not news in and of itself.

  6. There is also a jungle fungus that does this by lawpoop · · Score: 4, Interesting
    In a field study trip in Ecuador, we learned about a fugus that, as a spore, infects an insect and corrupts their nervous system, causing them to crawl to the top of whatever plant/tree they are on top of. Then, at the top, the fungus consumes the insect, while it is still clining to the branch. Then, the insect shell bursts open, spreading out spores from the upper canopy.

    VERY scary, very science fiction. What if this happened to people, but the behavior was at least passable, until it was 'too late'?

  7. What about cat parasites controlling humans? by tyroneking · · Score: 5, Interesting

    Basically, a parasite in cats passes to humans and a research study revealed that...
    "...women infected with toxoplasma spent more money on clothes and were consistently rated as more attractive. "We found they were more easy-going, more warm-hearted, had more friends and cared more about how they looked," he said. "However, they were also less trustworthy and had more relationships with men." "By contrast, the infected men appeared to suffer from the "alley cat" effect: becoming less well groomed undesirable loners who were more willing to fight. They were more likely to be suspicious and jealous. "They tended to dislike following rules," Flegr said."
    Here's the first link I could find that refers to the story I first read in the UK Times a while back (the link to the Times in the blog is broken but the best bit of the Times story was some suggestion that this parasite might explain the behaviour of the cat-loving French): http://althouse.blogspot.com/2005/06/have-cats-aff ected-your-brain-yet.html

    Ants have parasites as well according to this thread/discussion : "There is a parasite that cause behavioural change in ants. It's called lancet fluke. The parasitized ants become "ant zombies". They're influenced to cling to grass, until eventually eaten by herbivores. I sometimes find decapitated ant heads clinging to grasses. These may well be such cases."

  11. Interesting, but old news. by Kafir · · Score: 4, Informative

    It's been known for years, if not decades, that parasites can influence their hosts' behavior to the benefit of the parasite. There are flukes (genus Leucochloridium)with a life cycle that involves being transmitted from snails to other animals—the fluke affects the snail's brain and causes the snail to become light-seeking rather than light-avoiding, which means the snails climb to the tops of plants, where they are easy prey for birds—the next host in the fluke's life cycle. More about that (and the evolutionary logic behind it) here. Another fluke has a similar life cycle involving ants, which it drives to the tops of grass blades where they can be eaten by sheep (which again become its next hosts).

    A more obvious example might be rabies—animals with rabies ("mad dogs", most famously) have an irrational tendency to attack and bite other animals, unprovoked—which is how rabies is spread.

    What are the signs and symptoms of Guinea worm disease?

    A few days to hours before the worm emerges, the person might develop a fever and have swelling and pain in the area where the worm is. A blister develops and then opens into a wound. When the wound is immersed in water, the worm begins to emerge. Most worms appear on the legs and feet, but they can occur anywhere on the body. After the worm emerges, the wound often becomes painfully swollen and infected.
