DailyDirt: Fighting Biology With Biology

While most people have been taught to fear and loathe bacteria and other microscopic organisms (just watch some soap commercials), healthy people actually carry around more bacterial cells with them than their own human cells. It's estimated that there are ten times as many bacterial cells on a typical person than the number of cells that carry a person's own genetic code. About 100 trillion microscopic life forms usually live peacefully on (or in) our bodies, but the microbes that cause disease make us suspicious of all of them. In our battle to defeat the bad guys, though, we should be careful to limit the collateral damage. Here are just a few projects working on fighting "bad" bacteria without killing them all.

Acne plagues millions of people, and its treatments aren't always effective -- so how about some anti-acne viruses to kill off the bacteria that cause these pimples? The key trick is killing off just those specific bacteria and not all the beneficial natural bacteria that live on everyone's skin. [url]
A rare medical procedure, bacteriotherapy or fecal transplantation, attempts to restore a person's natural intestinal flora. Antibiotics can sometimes kill off too many microbes, making people sicker, and sometimes the solution is to re-create the right balance of microbes in a patient. [url]
Synthetic biology could create bacteria that prevent cavities, solve lactose intolerance, provide vitamins, and do all sorts of beneficial things for us. Imagine eating a yogurt that would replace the bacteria in your mouth or digestive tract... (and then wait 28 days for the zombie apocalypse). [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

seriously scary...
forget germ warfare... anti-biotic warfare will kill us all. we're creating all kinds of resistant strains of common germs that we won't be able to treat. thanks a lot, big pharma!

  Re: seriously scary...
  Oh even antibiotic becomes biological warfare. There is a reason you don't drink milk or eat dairies while on them.....fond memories in Jr. High of clearing an entire 30 person English class after catching pneumonia a month earlier...3 months of Antibiotics in a household that forced milk down your throat at any given moment, my parents got their karma soon enough from that :-)

Dental Caries Is A Bacterial Infection
Like all bacterial diseases, you can develop immunity. And some people are naturally immune.

  Caries is, isn't they?
