Pathogenic bacteria are bacteria that can cause infection.

In general, viruses are much smaller than bacteria.

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.

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.

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.

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.

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

Bacteriology is the study of bacteria.

Birds can be a significant source of fecal coliform bacteria.

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

All of these lesions harbor bacteria and are infectious.

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

There was no furniture in that room.

There were no roses in the garden.

Nuclear weapon free zones

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

Such materials may kill the fecal coliform and disease 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.

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.

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.

All samples were free of radiation.

All samples were free of radiation.

Find a big empty lot, make sure there's nothing in it and it's on private property, and let them drive your car.

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.

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

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

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

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.

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.

No solution is without weaknesses, though.

Build a government that is free of corruption, strong, resolute and effective.

However, it is probable that 99 of the bacteria come from about 30 or 40 species.

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.

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.
