Hello I'm Hank green welcome to scishow where we love slime slime is great except when it's the wrong kind of slime and when I say the wrong kind I mean the kind that can kill you biofilm also sometimes referred to as slime is a type of bacterial colony that produces a sticky organic glue which anchors the microorganisms to whatever service they fancy and also to each other making them exponentially better / worse than they would otherwise be it's also the latest addition to my list of things I wish it didn't have to worry about we didn't think of bacteria as freewheel and loners making their way through the world all by themselves and sometimes they are that way those are called planktonic bacteria but scientists are beginning to realize that bacteria actually spend most of their lives as biofilm which makes them way way way better at doing what they do whether it's helping us digest food or killing us with cholera just as living in towns and cities makes us more effective as a species bacteria living together as biofilm allows them to divvy up labour protect each other and share food and that frees up more time and resources to do the stuff like digesting in the killing their secret is the slimy goo that many bacteria secrete made up mostly of complex sugars called polysaccharides along with some proteins to form this sort of infrastructure of these bacterial towns this concoction of chemicals is actually very similar to a substance our own bodies create and that you may be familiar with mucus through this slime different bacteria can share nutrients in water they can also send signaling proteins to let them communicate they can even swap DNA to pass along their genes it's like the invited freakin Nations of germs up in there because this structure makes microorganisms so successful scientists estimate that 60 to 80 percent of the bacteria that cause human infection actually live as biofilm and because the only thing they need to start a colony is water they pretty much form in every environment on earth from super hot hot springs to the inside of your mouth in fact if you rub your tongue along your teeth right now you can probably feel maybe even taste the most widely known form of biofilm plaque which is actually a biofilm that contains up to 500 different species of bacteria and is the number one cause of periodontal disease other biofilms are responsible for even gnarlier infections like cystic fibrosis Legionnaires disease and all kinds of chronic ear sinus and skin infections to make matters worse their thick slimy matrix often makes biofilms antibiotic resistant one study found that bacteria in biofilm were a thousand times more resistant to antibiotics than the same bacteria where when they were on their own but the real city as part is that biofilms periodically shed their individual bacteria which then go off and start their own infections while antibiotics can kill these planktonic bacteria often making everything seem cool for a while the biofilm Deathstar is just hanging out there waiting to release more of its little thai fighters to attack the body again as a result biofilm infected tissue sometimes has to be removed surgically there that tenacious so I know it's gross and also it's scary so what are scientists doing to protect me and also you but more importantly me from biofilms well for now scientists are finding out more about them and how they work so that they can develop drugs that can break down the slime in order to help the antibiotics work at the bacteria within the film and what are we doing here at scishow well just know that we made a conscious decision to not show you any actual images or footage of biofilms in the human body so be thankful for that and have a good day and if you want to keep it in smarter with us here at scishow you can go to and subscribe you
