Zombie Plants Help To Spread Bacterial Pathogen 38
bmahersciwriter writes: "We've all heard stories about how parasites can 'zombify' organisms, getting them to mindlessly protect a brood or infect their peers. Now UK researchers have figured out how one bacterial pathogen co-opts the behavior of a plant, causing it to attract sap-sucking insects that help the bacteria spread to other plants. From the story in Nature News: 'The plant appears alive, but it's only there for the good of the pathogen,' says plant pathologist Saskia Hogenhout from the John Innes Centre in Norwich, UK. 'In an evolutionary sense, the plant is dead and will not produce offspring.' 'Many might balk at the concept of a zombie plant because the idea of plants behaving is strange,' says David Hughes, a parasitologist at Pennsylvania State University in University Park. 'But they do, and since they do, why wouldn't parasites have evolved to take over their behavior, as they do for ants and crickets?'"
Cold/Flu makes us zombies? (Score:3, Insightful)
The cold/flu causes us to produce additional muccus/sneeze/cough, altering our behavior which increases transmission rates. This doesn't mean we are zombies. I think it's a very interesting find, but a little ridiculous to involve the term zombie.

Similar analogy can be applied to virus infected computers which are often referred to as zombies. All they are doing, once infected, is trying to spread the infection. Depending on how aggressive the virus is the computer will become incapable of doing anything else. Which seems like a fair description of zombie behaviour.
