The beneficial bacteria that should colonise a healthy human digestive system are fuelled by the energy in food.

The theory runs that fermented foods introduce beneficial bacteria into the gut.

Science is now confirming ancient wisdom about fermented foods and the beneficial bacteria they contain.

This is because they help to maintain a balance between themselves and the billions of harmful bacteria that also live there.

This increases the risk of food poisoning as harmful bacteria splash from raw meat on to work surfaces.

But the process can be costly and detecting harmful bacteria remains their priority.

Drinking raw milk is not without risks as it can carry harmful bacteria.

Experiments showed that it could greatly increase the growth of the harmful bacteria.

Typically this occurs when the normal, healthy intestinal bacteria have been killed off by antibiotics.

It also appears to encourage the growth of beneficial intestinal bacteria.

This is because antibiotics can cause secondary infections by decreasing the population of important intestinal bacteria which keep yeast infections under control.

Maybe Lissa had pathogenic bacteria in her mix, as well as persuasive ones.

Colicin should be tested to control animal and foodborne pathogenic bacteria in livestock.

Nramp1 regulates iron efflux from the phagosomes, thus starving pathogenic bacteria for iron.

In other pathogenic bacteria, deletion of hydrogenase leads to a loss in acid resistance.

This strain of bacteria has become endemic in hospitals around the world and bloodstream infections often have proved lethal.

Obesity and irritable bowel syndrome are thought to be vulnerable to the right strain of bacteria.

The isolated strain of bacteria belongs to neutrophilic and mesophilic microorganisms.

Marine invertebrates, as holobionts, contain symbiotic bacteria that coevolve and develop antimicrobial substances.

As in all studied lucinids, the new species possesses symbiotic bacteria housed in the ctenidia.

Nitragina inoculant, as a source of symbiotic bacteria, was applied before sowing seeds.
