Griffith concluded that the type II R had been transformed into the lethal III S strain by a transforming principle that was somehow part of the dead III S strain bacteria.

Griffith used two strains of pneumococcus ( Streptococcus pneumoniae ) bacteria which infect mice a type III S (smooth) and type II R (rough) strain.

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.

Equipped with this gene, the former II R strain bacteria were now protected from the host's immune system and could kill the host.

Strain

Pathogenic bacteria are bacteria that can cause infection.

Bacteriology is the study of bacteria.

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

Yet freedom of speech in the West is under strain.

The Russian strain of political messianism is pretty much exhausted.

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

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.

All of these lesions harbor bacteria and are infectious.

This relationship, however, is not always without strain.

Prolonged periods of strain tend to weaken the fabric of institutional cooperation.

Bacteria can spread also via the blood.

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.

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

In general, viruses are much smaller than 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.

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.

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

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

One strain of HPAI A(H5N1) is spreading globally after first appearing in Asia.

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.

For example, additional letters may be added to indicate a strain.

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.

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.

DNA transfer Some bacteria also transfer genetic material between cells.

Such materials may kill the fecal coliform and disease bacteria.
