Micromotors created for drug delivery

University of California-San Diego researchers have successfully tested out drug-delivery micromotors to deliver a therapeutic agent to treat bacterial infections of the stomach.

Reducing organ rejections using 'lethal' bacterial enzyme

Researchers have developed a novel type of drug therapy using an enzyme extracted from bacteria that are normally considered harmful. The aim is to use the enzyme to reduce organ rejection rates following kidney transplants.

Shark skin inspires new antibacterial surface

A new type of antibacterial surface technology has been developed. The inspiration for the surface came from a study of the skin of sharks. The surface has been commercialized by a company called Sharklet Technologies.

Cases of superbug Clostridium difficile increase

The most troubling cases of C. difficile infection, termed multiple recurring C. difficile infections (mrCDI), are becoming more common, according to a new university research study.

Antibiotic resistance linked to household disinfectant triclosan

Birmingham - British scientists have found a connection between a significant mechanism of antibiotic resistance to the disinfectant triclosan. This chemical is found in many common domestic products.

Therapy alternative to farm animal antibiotics

London - Despite longstanding scientific concerns, antibiotics continue to be given to farm animals as a means of producing leaner meat. This helps to spread antibiotic resistance. A new type of therapy offers an alternative.

BBC finds fecal bacteria in drinks from Starbucks

It's hard to match the refreshing taste of an iced coffee on a hot summer day — but a new BBC investigation may make you think twice before you order a chilled drink.

Lowering cholesterol thanks to artificial prebiotics

Budapest - A new study indicates that a naturally synthesized prebiotic can target and increase the growth of bacteria in the human gut which lead to a reduction in cholesterol levels. The research comes from the University of Reading in the U.K.

Tackling autism by targeting gut bacteria

Beijing - As part of the research into probiotic and prebiotic supplements, researchers have reported on indications that suggest altering the bacteria found in the human gut could help to address the symptoms of autism.

New technology makes electricity from urine

Bristol - An emerging biotechnology process that allows electricity to be generated from urine is closer to realization, following a new study produced by the University of the West of England.

Can probiotics reduce symptoms of depression?

Can probiotics help to reduce the symptoms of depression? The answer appears 'possible', based on new research. McMaster University scientists have shown a beneficial connection between the microbiota-gut-brain axis.

Faster and accurate test for sepsis invented

Tongde - Medical technologists have constructed a test designed to rapidly and reliably diagnose sepsis. Sepsis is a potentially life-threatening complication arising from bacterial infections.

Unnecessary antibiotics still prescribed for colds

Toronto - There has been plenty of publicity about prescribing antibiotics for viral infections, yet the problem continues within the medical community, according to a study of U.S. health sector practices. The problem connects with the antibiotic resistance issue.

Flame retardant material from bacteria-on-sponge

San Diego - Bacteria found on a marine sponge can produce toxic flame retardant-like compounds, according to a new study. Researchers are investigating the human health implications of the discovery.

Most contaminated places in the home identified

Philadelphia - There's been a lot of coverage about contamination in the environment and microbial risks in hospitals, but how about your home? Two new studies highlight the dirtiest places in the typical house.

Natural defense mechanism against TB discovered

London - A new study from London’s Francis Crick Institute shows how the human body protects itself from the bacterium that causes the disease tuberculosis. This could open up a new way for fighting the disease.

Gold processing bacteria help to recycle electronics

Adelaide - There are species of bacteria that efficient at processing of gold ore. Applications include recycling electronics as well as use in exploration for new deposits. A new study demonstrates the advantages.

Phage therapy aids man with multidrug-resistant infection

A novel application of bacteriophage therapy has saved the life of a man who contracted a multi-drug resistant bacterial infection. Phage therapy offers a promising new take on the fight against antibacterial resistance.

Essential Science: Bacterium mutates into dangerous pathogen

A microbe has moved from a common resident of the throat and nose to become a potentially worrisome sexually transmitted pathogen. The organism is called Neisseria meningitides and it can cause something a bit like gonorrhea.

Harnessing silver for the antimicrobial fight

The use of silver to fight infections has been in place for thousands of years. Silver can still play a major role in the antibiotic fight. Researchers are using modern gene editing techniques to see how silver poisons pathogens.

Bad mix of gut microbes triggers age-associated inflammation

Inflammation increases with age and this leads to ill-health problems. One of the triggers appears to be the balance of microorganisms in the gut. This is based on studies using mice and the findings may well apply to people.

Insight into how anthrax evades the immune system

Cells of the bacteria which causes the disease anthrax are able to trigger an unfavorable immune response which allows the organism to evade attack from the body’s defense system. This relates to differences with the bacterium in the spore state.

Pancreatic cancer connected to mouth bacteria

New York City - The oral microbiome (that bacteria found in the mouth) can, if imbalanced, enhance the risk of a person developing pancreatic cancer. The finding adds to growing reports about the association between human microbes and disease.

Magnetic brain stimulation causes weight loss

Milan - Can weight loss be achieved through the technique of magnetic brain stimulation? A recent study suggests this is possible and it works by altering the composition of the bacteria that reside in the human gut.

Killer whale breath bacteria highlight endangered species

Scientists have discovered that droplets in exhaled breath caught from the blowholes of killer whales provide insights into the health of the whales. Additionally, certain bacteria and fungi are a particular threat to killer whales.

Wood based water filter offers emergency solution

Stockholm - Wood extracted from the forests of Scandinavia provides a solution to not having clean water in areas where there are no clean eater sources or filters. Applications include parts of the developing world and refugee camps.

Most cookbooks give bad food safety advice

Cooks beware. A new study has found that many bestselling cookbooks provide readers and would-be chefs with little in the way of useful advice about reducing food-safety risks. Worryingly, where advice is given it is often erroneous.

Microbiologists reveal the infectiveness of Chlamydia

Chlamydiae are highly infective bacteria. They survive in human cells in multiple ways. One newly discovered mechanism is where the invasive organisms manipulate human cells energy suppliers.

Medical breakthrough in tuberculosis diagnosis

Birmingham - Scientists have made a significant advance in the rapid detection of tuberculosis. This is based on genome sequencing and allows different strains of the infectious organism to be isolated.

Connection between gut microorganisms and Parkinson’s disease

A new connection between the microbiome of the gut and human health and disease has been made. Here Parkinson's disease, along with the medications to treat Parkinson's, alter the composition of the trillions of bacteria that make up the gut microbiome.
