Pathogenic bacteria are bacteria that can cause infection.

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.

Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi.

As with bacterial classification, identification of bacteria is increasingly using molecular methods.

Bonnie Bassler on how bacteria talk

Without water, the bacteria won't survive.

They also kill bacteria essential to the proper balance of the aquatic environment, endangering the survival of species dependent on those bacteria.

In general, viruses are much smaller than bacteria.

Bacteriology is the study of 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.

Xylitol cannot be fermented by these bacteria, so the bacteria have difficulty thriving, thus helping to prevent plaque formation.

Such materials may kill the fecal coliform and disease bacteria.

Once in the lungs, bacteria may invade the spaces between cells and between alveoli, where the macrophages and neutrophils (defensive white blood cells) attempt to inactivate the bacteria.

Identification of bacteria in the laboratory is particularly relevant in medicine, where the correct treatment is determined by the bacterial species causing an infection.

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

Bacteria are also used for the bioremediation of industrial toxic wastes.

Bacteria can spread also via the blood.

One of the interesting things about these particular guys is that they're in the actinomycete and streptomycete groups of the bacteria, which is where we get most of our antibiotics.

Birds can be a significant source of fecal coliform bacteria.

PAOs are by no means the only bacteria that can accumulate polyphosphate within their cells and in fact, the production of polyphosphate is a widespread ability among bacteria.

All of these lesions harbor bacteria and are infectious.

This elevated temperature heat shocks non fecal bacteria and suppresses their growth.

The amount and type of bacteria present have significant implications for a woman's overall health.

The physician may also take a stool sample to test for infections or bacteria.

This reaction occurs in the photosynthetic green and purple sulfur bacteria and some chemolithotrophs.

And so we use a virus that's a non toxic virus called M13 bacteriophage that's job is to infect bacteria.

As a result, many bacteria today produce human proteins.

Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.

The final phase is the death phase where the bacteria run out of nutrients and die.

Bacteria can also be used in the place of pesticides in the biological pest control.

It is responsible for the bacteria's ability to spread from person to person and is analogous to a spore.

Bacteria capable of digesting the hydrocarbons in petroleum are often used to clean up oil spills.

Photolysis of water occurs in the thylakoids of cyanobacteria and the chloroplasts of green algae and plants.

In general, atargeting construct made out of DNA is generated in bacteria.

Bacteria make up most of the flora in the colon and 60 of the dry mass of feces.

It is a streptogramin group antibiotic, similar to virginiamycin, derived from the bacterium Streptomyces pristinaespiralis .

What you're looking at on this slide is just a person from my lab holding a flask of a liquid culture of a bacterium, a harmless beautiful bacterium that comes from the ocean, named Vibrio fischeri.

And the way bacteria make a living is that they consume nutrients from the environment, they grow to twice their size, they cut themselves down in the middle, and one cell becomes two, and so on and so on.

It's a natural process. It goes on in nature today, and the bacteria die as soon as we stop feeding them.

In natural environments, such as soil or the surfaces of plants, the majority of bacteria are bound to surfaces in biofilms.

Additional mutations, however, may compensate for this fitness cost and can aid the survival of these bacteria.

Adding specific strains of bacteria to pasteurized milk allows more consistent production.

B12 that is to be used in these supplements is typically grown from vegan sources (such as bacteria).

If bacteria are to survive, then they must obtain iron from their environment.
