Pathogenic bacteria are bacteria that can cause infection.

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

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

Already what were thought to be bacteria for generations have been found to compose, instead, two great domains of microorganisms true bacteria and one celled organisms the archaea, which are closer than other bacteria to the eukaryota, the group that we belong to.

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.

Bonnie Bassler on how bacteria talk

Without water, the bacteria won't survive.

Bacteriology is the study of bacteria.

Bacteria can spread also via the blood.

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.

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

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

In purple sulfur bacteria, hydrogen sulfide (H2S) is oxidized to sulfur (S).

High traffic areas will lead to even more bacteria on the food.

Bacteria can feed upon this food source allowing them to quickly multiply.

In general, viruses are much smaller than bacteria.

Bacteria In the first decades of the 20th century, the term pleomorphism was used to refer to the idea that bacteria changed shape dramatically or existed in a number of extreme morphological forms.

This provides nutrition to the black fly larvae, as well as the bacteria.

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

There are more bacteria than any other life form.

As a result, many bacteria today produce human proteins.

All of these lesions harbor bacteria and are infectious.

As with malaria, the TB bacteria had developed resistance to the traditional therapeutic drugs.

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

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

Sami injected bacteria in some of the pastries Layla ate.

DNA transfer Some bacteria also transfer genetic material between cells.

Birds can be a significant source of fecal coliform bacteria.

Such materials may kill the fecal coliform and disease bacteria.

The bacterial outer membrane is found in gram negative 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.

The real bacteria and viruses are so small we can't see them without a microscope, and you guys might know bacteria and viruses because they both make us sick.

Bacteria should be checked for two types of mutation adaptation by a hostile form that enables it to become super immune to drugs, or a deadly mutant strain that appears in one of the multitude of safe bacteria.

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

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

Certain compounds of germanium have low toxicity to mammals, but have toxic effects against certain 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.

It may become permeable to these types of cells secondary to an infection by a virus or bacteria.

The chromosome was modified to eliminate all genes which tests in live bacteria had shown to be unnecessary.

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

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

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

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

Like other beans, it hosts bacteria that fix nitrogen in the soil.

If food becomes contaminated with bacteria and remains at room temperature for a period of several hours, the bacteria multiply and increase the risk of infection in those who consume the food.
