Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. This highly specialised interaction between an insect species and bacteria protects the insect's offspring against microorganisms which might infect it during its cocoon stage. (2007-03-31)

Single cell amoeba increases MRSA numbers 1000- fold
Scientists in the UK have found that a type of amoeba acts as an incubator for MRSA bacteria. As amoebae are often found in healthcare environments this discovery has implications for the infection control strategies adopted by hospitals. (2006-03-31)

Antibiotic resistance is a gut reaction
Scientists from the Institute of Food Research and the University of East Anglia have discovered how certain gut bacteria can protect themselves and others in the gut from antibiotics. (2014-12-16)

Why recovery from flu may increase odds of bacterial infection
Successfully fighting off the flu can leave you more vulnerable than usual to other lung infections. A new study shows that flu infection in mice causes immune cells to ignore later infections. The study will appear in the Feb. 18 issue of the Journal of Experimental Medicine. (2008-02-18)

Smart bacteria help each other survive
The body's assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron.

(2007-12-19)

Backstabbing bacteria: A new treatment for infection?
Selfish bacterial cells that act in their own interests and do not cooperate with their infection-causing colleagues can actually reduce the severity of infection. The selfish behaviour of these uncooperative bacteria could be exploited to treat antibiotic-resistant infections, according to research being presented at the Society for General Microbiology's autumn meeting today. (2010-09-05)

Children with and without multiple sclerosis have differences in gut bacteria
In a recent study, children with multiple sclerosis had differences in the abundance of specific gut bacteria than children without the disease. Certain types of bacteria were either more or less abundant in children with multiple sclerosis. In particular, there was an association between multiple sclerosis and an increase in gut bacteria that have been linked to inflammation and a decrease in gut bacteria that are considered anti-inflammatory. (2016-05-16)

Research shows how bacteria communicate with each other
A pathway whereby bacteria communicate with each other has been discovered by researchers at the Hebrew University of Jerusalem. The discovery has important implications for efforts to cope with the spread of harmful bacteria in the body. (2011-03-02)

Paradigm shift: 'We need to study lumps of bacteria'
New research from the University of Copenhagen reveals that bacteria which agglutinate before entering the body are far more resistant than single-celled bacteria. This may be the cause of chronic infections. (2016-03-23)

Bacteria could become a future source of electricity
In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, researchers from institutions including Lund University have achieved a slightly more efficient transfer of electrical current. (2019-03-26)

Recognition of bacteria in the cytosol by the immune system
Researchers identified a previously unappreciated way in which bacteria can be recognized inside our cells. Their findings suggest that Salmonella bacterial proteins are detected by the ubiquitin system and destroyed by the proteasome within the cytosol during infection, and that this may play a key role in activation of the immune system. Surprisingly, they also found that Listeria and other bacteria that can colonize the cytosol do so in a manner that prevents activation of the immune system. (2004-05-03)

Bacteria That Disable Sperm
Some men have low fertility because of microorganisms lurking in their semen, say researchers in Hungary. They have shown that anaerobic bacteria, present in up to two-thirds of men, can prevent sperm from swimming well enough to reach an egg. (1998-10-14)

Antibiotics-resistant gulls worry scientists
The resistance pattern for antibiotics in gulls is the same as in humans, and a new study by Uppsala University researchers shows that nearly half of Mediterranean gulls in southern France have some form of resistance to antibiotics. The study is being published today in the journal PLoS One. (2009-06-18)

Captain Birdseye's robotic nose
The captain can't freeze smelly fish that's past its best -- and Icelandic scientists can now help him out by detecting the levels of stench-making bacteria faster than ever before.

Frontal attack or stealth?
New research shows that bacteria that are able to invade cells of the host's immune system have higher infectivity, whereas those that are more motile, multiply faster and communicate with each other need more bacterial cells to trigger an infection. These findings help understand the patterns that shape infectivity of bacteria, and contribute to more accurate predictions of how emerging pathogens may evolve, with implications for public health. (2012-02-27)

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria
Scientists at the University of Texas at Austin have developed a quick and simple way to investigate the sugar coating that surrounds bacteria and plays a role in infection and immunity. The sugars coating bacteria can change very quickly during the course of an infection, cloaking the bacteria from the immune system of their host. (2006-02-13)
