Bonnie Bassler: The secret, social lives of bacteria
Trki, Kody, Cheaty do
http://www.ted.com Bonnie Bassler discovered that bacteria "talk" to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry -- and our understanding of ourselves. See this INTERVIEW with Bonnie Bassler, "the Bacteria Whisperer" on the TED Blog: http://blog.ted.com/2009/04/the_secret_soci.php TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes.

She says bacteria get resistant to antibiotics because we select for them. This is true, but don't we also select for bacteria resistant to quorum sensing inhibitors? When cells that have inhibited communication are less fit, then there can and will emerge a mutation in the receptor leading to reduced binding of the inhibitor. Which is exactly the same principle like resistance to antibiotics.

How does disabling the inter species quorum sensing stop the bacteria from multiplying?
-
"Simple organisms"? If that were true, we'd be able to recreate them in a test-tube.
Single celled organisms are horribly complex, so much so that understanding them is akin to understanding the workings of the brain or pushing our understanding of existence through the Big Bang and out the other side.
What concerns me is the Human brain may be far more complex than we are.
Think about it. -
How can the majority of us be bacteria if they only contribute to 3 lbs of our weight?
-
Maybe it makes more sense to make lonely bacteria think that there is a lot of another bacterias and its time to attack using fake chemicals. A small amount of bacteria will not cause a lot of damage.

Such an amazing talk!

Awesome lesson. You should do this for LYME DISEASE, as this has now become a global epidemic. The CDC has reported that now there are over 300,000 new cases/year and this now passes HIV+/AIDS cases well beyond. It is said the real world numbers are more like 1-3 million new cases. Borrelia burgdorferi, one of the bacteria responsible for Lyme Disease, produces outer surface protein OSP-A (in ticks) & OSP-C (in humans), which might be used in quorum sensing & which might be able to be exploited.
New studies have also implicated this bacteria in causing Alzheimer's disease, MS, Fibromyalgia, & Morgellon's disease. So your work on this Borrelia genus can affect millions & millions of people and save the economy a few billion. -
Because they will evolve. If antagonists failed. He'll mess up our language and could not reach the bacteria coexist. Then, we will turn into a zombie?

She simply love her job

Bonnie is always so passionate in her lesson. So go at public speaking. Probably because microbiology is my major, so I don't feel too fast

woohooo... Great talk

Wow, amazing talk! People criticizing the speaker....number 1 she is on the clock - that's why towards the end once she looked at the monitor in front of her which has a timer, she sped up. Number 2 - people who speak like she does are passionate!!! She clearly loves what she does and is excited to share it with others. There is no need for the negativity.
