Bacteria are microscopic organisms.

To take an example close to home there are over 500 species of bacteria now known friendly bacteria living symbiotically in your mouth and throat probably necessary to your health for holding off pathogenic bacteria.

And it's killing bacteria. It's eating them.

Bacteria usually form colonies.

Bacteria are everywhere.

Bacteria are incredibly multi drug resistant right now, and that's because all of the antibiotics that we use kill bacteria.

So we went back to molecular biology and started studying different bacteria, and what we've found now is that in fact, bacteria are multilingual.

As usual there are exceptions such as the halophilic algae and bacteria.

Iron or manganese used by prokaryotes and protists, and in mitochondria Iron E. coli and many other bacteria also contain a form of the enzyme with iron (Fe SOD) some bacteria contain Fe SOD, others Mn SOD, and some contain both (e.g., E. coli ).

Bacteria are invisible to the naked eye.

Bacteria reply in an autonomous fashion.

Bacteria are just tiny cells, harmless.

And the bacteria are feeding on the sugar nutrients in the liquid.

We kill bacteria with traditional antibiotics and that selects for resistant mutants.

And when the molecule hits a certain amount that tells the bacteria how many neighbors there are, they recognize that molecule and all of the bacteria turn on light in synchrony.

We was so, so stupid. The most stupid bacteria.

Bacteria will not breed in alcohol.

And along comes pneumococcus or another bacteria, streptococcus and boom, they get a bacterial pneumonia.

You need the bacteria to fix nitrogen, and without those microorganisms, you won't have any performance at all.

And these are mineral deposits that are also made by bacteria.

Viruses are much smaller than bacteria.

How does nature repel bacteria?

You look in his intestines. There are billions of bacteria.

Bonnie Bassler on how bacteria talk

Is it bigger than the biggest bacterium? We don't know.

And for certain bacteria we don't have really efficient ways to do that anymore.

It has no bacteria on its surface, no fouling on its surface, no barnacles.

So how does it keep its body free of bacteria build up?

Bacteria always control pathogenicity with quorum sensing.

It's used by all different bacteria and it's the language of interspecies communication.

We can also see blooms of bacteria, blooms of viruses in the ocean.

Bacteria are the oldest living organisms on the earth.

Everything is covered in invisible ecosystems made of tiny lifeforms bacteria, viruses and fungi.

So when we think about future technologies, we actually think of using bacteria and virus, simple organisms.

It recognizes when it has enough bacteria that now they're going to launch their attack, and the animal dies.

It's because they used to be separate free living bacteria and they came together and became a superorganism.

So probably it doesn't matter 50 years from now streptococcus and stuff like that will be rampant because we won't be here. But if we are we're going to need something to do with the bacteria.

The bacteria that are transferred during a kiss help improve your immune system.

These bacteria are not passive riders, these are incredibly important, they keep us alive.

Of course what that allows bacteria to do is to be multicellular.

An analogue would be the growth of bacteria in a petri dish.

Bacterial pneumonia is a type of pneumonia caused by bacterial infection.

Providencia is a Gram negative, motile bacterium of the family Enterobacteriaceae.

Pathogenic bacteria in milk, such as salmonella and coliforms, can cause food borne illness.

In 48 hours to 72 hours, these three mushroom species reduced the amount of coliform bacteria 10,000 times.
