Pathogenic bacteria are bacteria that can cause infection.

And my favorite example of that occurred beginning in 1976, when it was discovered that the bacteria causing Legionnaires disease had always been present in natural waters, but it was the precise temperature of the water in heating, ventilating and air conditioning systems that raised the right temperature for the maximum reproduction of Legionella bacillus.

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

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.

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

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

In general, viruses are much smaller than 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.

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.

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.

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.

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.

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 are also used for the bioremediation of industrial toxic wastes.

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.

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

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

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.

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

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

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

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.

In general, Th1 responses are more effective against intracellular pathogens (viruses and bacteria that are inside host cells), whereas Th2 responses are more effective against extracellular bacteria, parasites including helminths and toxins.

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.

These studies emphasize the relationships between plants, animals and bacteria and their environment.

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

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

Well preserved bacteria older than 3.46 billion years have been found in Western Australia.

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.
