Essential Science: Why nitrogen is a key driver for gut health

Researchers have moved closer to connecting diets and dieting strategies and a healthy gut. This fits together with the need for having the right balance of microorganisms, and here nitrogen plays a key role.

Trouble with contact lenses? Might be your microbiome

Some people cope well with contact lenses, other suffer with itchy eyes or run into problems. The reason may be due to the microbial composition of the eye, according to a new study.

Antimicrobial resistant bacteria detected in air pollution

Areas subject to air pollution contain a growing concentration of bacteria that are resistant to antimicrobials, according to a new study. Consequently, air movement may provide a new ways for their transmission.

Battle with super-bugs moves onto tackle E. coli

London - With success achieved in reducing incidences of MRSA, the British government has moved its focus towards reducing the number of cases of the bacterium Escherichia coli in hospitals.

Rapid method for diagnosing sepsis

Although there are tell-tale signs for sepsis (such as a rise in body temperature and faster breathing), a fast diagnoses is essential. Traditional methods use blood culture, which takes time. To overcome this, a rapid method has been developed.

Mouth bacteria linked to migraines

Migraines are triggered by many different factors, from lack of sleep, stress and by certain foods. A new study indicates that the microorganisms resident in the mouth may also play a part.

New drug target designed to attack gut bacteria

Gastroenteritis is caused by some foodborne bacteria. Researchers have designed a new antimicrobial drug to take on one of the world’s most prevalent foodborne bacteria.

Milk from Tasmanian devils helps fight superbugs

It seems one of the strange science stories of the week, but Australian scientists have discovered that the milk from Tasmanian Devils has antimicrobial properties, including activity against antibiotic resistant organisms.

Rapid test for tuberculosis developed

Austin - A rapid, accurate and inexpensive test for tuberculosis has been developed by a researcher based at the Texas A&M University Health Science Center. The test is called TB Read.

New process aims for germ free computer keyboards

Some people are aghast at the idea of sharing computers, due to the risk of pathogenic germs being found on keyboards. A new treatment aims to render keyboards 99 percent bacteria free.

Essential Science: Saturn’s moon contains an underground ocean

Reviewing data from the Cassini spacecraft, astrophysicists think there’s a strong chance that the Saturnian satellite Dione contains a vast underground ocean.

New evidence for the role of bacteria in incontinence

The feeling of suddenly having to urinate is an unpleasant one and repeated occurrences can affect many people. The underlying causes are varied, although one factor may be microbial in origin.

New insight into bacterial drug resistance

Researchers are investing time and resources trying to understand how pathogenic bacteria function, in a quest to find new ways to inhibit and kill the disease causing organisms.

Antimicrobial resistance occurs naturally in soil bacteria

Bacteria, isolated from soil and with no known contact with human society, have been shown to exhibit antimicrobial properties. The organisms were isolated from in prairie soils.

First gut bacteria and visceral body fat connection

A connection has been drawn between certain types of bacteria, as recovered in human feces, and levels of abdominal body fat. This could suggest a link between inherited bacteria and obesity.

New insight into why anthrax is so deadly

To delve into the toxicity of anthrax, scientists have constructed a three-dimensional map of the anthrax toxin. The model shows how the toxin is efficiently transferred into the cytoplasm of cells.

Bacteria, dirt and stress — is a little less hygiene needed?

Increasing concerns about personal cleanliness, especially with children, could be linked to a reduced the diversity of our microbiomes and increased the prevalence of inflammatory and stress-related diseases.

Magnetic bacteria used to deliver anti-cancer drugs

A new research project has shown promise in using magnetic bacteria as a vehicle for delivering anti-cancer drugs more accurately to tumors in patients.

Putting ‘feed a cold, starve a fever’ to the test

It’s an old wives tale – “feed a cold and starve a fever.” But does it come with any scientific basis? One research laboratory has put the aphorism to the test.

Essential Science: New pathogen causes anthrax like disease

A new report has detected a species of Bacillus, genetically distinct to the bacterium that causes anthrax, which causes a similar disease in chimpanzees, gorillas and other animals in Africa.

New genus of bacteria found in fracking wells

Dig deep and there are potentially hundreds of bacteria on Earth that have yet to be discovered or characterized. One recent discovery relates to fracking where a new genus of bacteria has been discovered.

Cause of the Great Plague of London identified

London - In 1665 London was ravaged by a deadly plague that was only stopped by an equally great fire. New evidence, from examining bones of the victims, has pinpointed the causative organism.

Bacteria in the blood could trigger dozens of diseases

Are bacteria in the human blood system responsible for indirectly triggering a range of diseases? New research suggests a link to strokes and heart attacks, and other ill-health conditions.

Tomatoes may hold the key to crop disease resistance

Agricultural scientists have isolated a receptor used by tomatoes to detect the infectious agent that causes bacterial speck disease. The receptor could be transferred into other crops to make them disease-resistant.

Stillbirth and bacteria linked for first time

A common type of bacteria, carried by many women, has been linked with premature delivery and stillbirths. This understanding may help to reduce the number of deaths.

Modified bacteria protect against obesity

Introducing genetically modified bacteria into the intestines of mice appears to protect the rodents from obesity. This could become a treatment option for people.

Jefferson Memorial covered in microbial slime

Washington - Over the past ten years the Jefferson Memorial has turned from a white-ish sandstone color to a dark-grey. This has happened due to a microbial biofilm.

New types of African Salmonella trigger infection concerns

A global study of Salmonella enteritidis bacteria (which causes blood poisoning) has found three separate types of bacteria. This indicates that control of infection risks could become more complicated.

Sabotaging bacteria to halt infections

Some bacteria have the ability to ‘swim’ in a controlled fashion through the use of appendages called flagella. Researchers think that disabling these flagella is a key step towards infection control.

Magnetic bacteria carry anti-cancer drugs to tumors

Toronto - Studies have taken place in Canada whereby magnetic bacteria are used to power nano-devices, to help ferry anti-cancer medicines to sites of tumors. Such devices offer faster and more precise drug delivery.
