Pathogenic bacteria are bacteria that can cause infection.

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

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

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

Bacteriology is the study of bacteria.

Fecal coliform bacteria can enter rivers through direct discharge of waste from mammals and birds, from agricultural and storm runoff, and from human sewage.

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

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

This vast domain of hidden biodiversity is increased still further by the dark matter of the biological world of bacteria, which within just the last several years still were known from only about 6,000 species of bacteria worldwide.

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.

Such materials may kill the fecal coliform and disease bacteria.

The bacterial outer membrane is found in gram negative bacteria.

Although fermentative bacteria are not strictly dependent on syntrophyic relationships, they still gain profit from the activities of the hydrogen scavenging organisms, as the fermentative bacteria gain maximum energy yield when protons are used as electron acceptor with concurrent H2 production (Dolfing, 1988 Schink, 1997).

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.
