Bacteriophage-based method may improve efficiency of bacteria detectors

Viruses that attack bacteria - bacteriophages - can be fussy: they only inject their genetic material into the bacteria that suit them. The fussiness of bacteriophages can be exploited in order to detect specific species of bacteria. Scientists from Warsaw have just demonstrated that bacteriophage-based biosensors will be much more efficient if prior to the deposition on the surface of the bacteriophage sensor their orientation is ordered in electric field.

Macrophages play key role in maintaining healthy arteries after inflammation

Researchers from the University of Toronto have found that a specific cell type plays a key role in maintaining healthy arteries after inflammation. It's a discovery that could provide treatment options for cardiovascular disease -- one of the leading causes of death in Canada.

Stanford researchers invent new technique to dramatically accelerate protein evolution

All living things require proteins, members of a vast family of molecules that nature "makes to order" according to the blueprints in DNA.

ESCMID’s EUCAST plays key role in defining antimicrobial resistance in Europe and globally

The European Society of Clinical Microbiology and Infectious Disease (ESCMID) – an organization that pursues science, explores risk assessment, knowledge sharing and best practices in the fight against infectious disease – is currently researching the new critical breakpoints for antimicrobial agents in clinical development through its European Committee on Antimicrobial Susceptibility Testing (EUCAST).

Scientists decipher details of cloaking proteins that protect the toxin that causes botulism

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators at Stony Brook University and the Institute of Advanced Sciences in Dartmouth, Massachusetts, have discovered new details about how "cloaking" proteins protect the toxin that causes botulism, a fatal disease caused most commonly by consuming improperly canned foods.

Reduced antibiotic prescribing associated with lower patient satisfaction

Reduced antibiotic prescribing is associated with lower patient satisfaction on the national General Practice Patient Survey, according to a new study by King's College London. The study found a 25 per cent lower rate of antibiotic prescribing by a GP practice corresponded to a 5-6 point reduction on GP satisfaction rankings.

New GASMAS-based technique shows promise for non-invasive sinusitis diagnostics

A team of scientists from the South China Normal University (Guangzhou, China) and the Lund University (Sweden) led by Sune Svanberg now presents a new approach for a non-intrusive optical technique for human sinus realtime diagnostics that could be developed into a cost-effective, easy-to-use hand-held instrument.

Prophylactic antibiotics reduce risk of serious bacterial infections in children with ALL

Prophylactic antibiotics significantly reduce the risk of serious bacterial infections in children during the critical first month of treatment for acute lymphoblastic leukemia (ALL), the most common childhood cancer, according to a U.S. and Canadian study led by investigators from Dana-Farber/Boston Children's Cancer and Blood Disorders Center.

Our appetite is dictated by gut bacteria

Bacteria in our stomachs might be deciding when we’ve eaten enough and switch off appetite, according to new research.

Bacteriophage therapy: an alternative to antibiotics? An interview Professor Clokie

A phage is a virus that infects a bacterium. People often get very confused about what the difference is between a virus and a bacterium. A virus, like a bacterium, is also a microorganism, but unlike bacteria, it needs to have a host to be able to replicate and propagate.

Novel class of antimicrobials could be effective in fighting drug-resistant MRSA infection

A novel class of antimicrobials that inhibits the function of a key disease-causing component of bacteria could be effective in fighting methicillin-resistant Staphylococcus aureus (MRSA), one of the major drug-resistant bacterial pathogens, according to researchers at Georgia State University.

Research highlights importance of controlling hospital and nursing home infection

A Rhode Island Hospital and The Miriam Hospital study found that a small percentage of nursing home patients carrying multi drug-resistant bacteria are admitted to hospitals without showing symptoms caused by the bacteria. The research, published in the American Journal of Infection Control, highlights the importance of hospital and nursing home infection control practices.

Innovative compound with anti-MRSA qualities may help develop new class of antibiotics

With global health services increasingly worried about the rise of antibiotic resistant diseases, researchers at Maynooth University have discovered a compound whose anti-MRSA qualities pave the way for the development of a new class of antibiotics.

Scientists can accurately measure microbial growth rates inside gastrointestinal tracts

For the first time, scientists can accurately measure population growth rates of the microbes that live inside mammalian gastrointestinal tracts, according to a new method reported in Nature Communications by a team at the Wyss Institute for Biologically Inspired Engineering at Harvard University and Harvard Medical School.

Seaweed extract shows promise in treating H. pylori-related diseases, gastric cancer

A unique seaweed extract shows promise for the treatment of Helicobacter pylori-related diseases and gastric cancer, according to new research undertaken at the University of Western Australia.

E. coli can move faster and farther in syrup-like fluids than in water, say Penn researchers

Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it's easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn't understand why.

WPI researchers awarded $1.3 million NIH grant to study use of copper to battle bacterial invader

Copper is an essential micronutrient that all organisms need to maintain healthy metabolism. But unless it is bound to proteins, copper is also toxic to cells. With a $1.3 million award from the National Institutes of Health, researchers at Worcester Polytechnic Institute will conduct a systematic study of copper in the bacteria Pseudomonas aeruginosa (P. aeruginosa), a leading cause of hospital-associated infections that is increasingly resistant to antibiotics, with the hope of discovering new drug targets that might allow cells in the body to use copper to fight back against this bacterial invader.

Scientists create detailed image of deadly toxin linked to bacterial pneumonia, meningitis, septicaemia

Scientists from the University of Leicester have for the first time created a detailed image of a toxin - called pneumolysin - associated with deadly infections such as bacterial pneumonia, meningitis and septicaemia.

Pre-travel advice may not reduce risk of illnesses during travel

Travelling abroad involves risk of illnesses and carriage of antibiotic resistant bacteria, especially among students. Illnesses such as travellers' diarrhoea and respiratory tract infections are most common. Even if travellers follow the travel medicine clinics' advice on how to reduce risks during travel, the risk of falling ill is not reduced.
