Decreasing inappropriate antibiotic use is key strategy to control drug resistance

Antibiotic resistance is a larger public health threat than most people realize. And, the Centers for Disease Control and Prevention reports about half of all antibiotics in outpatient settings are incorrectly prescribed.

Software tool can predict how drugs can be combined to create effective treatments

With a shortage of new tuberculosis drugs in the pipeline, a software tool from the University of Michigan can predict how current drugs--including unlikely candidates--can be combined in new ways to create more effective treatments.

Researchers study the effects of hyperoxia on the lung development of germ-free newborn mice

Charitharth Vivek Lal, M.D., and University of Alabama at Birmingham colleagues have used a novel and first-of-its-kind newborn mouse model to study the effect of high oxygen concentrations, or hyperoxia, on lung development of newborn mice that are germ-free -- meaning no microbes colonizing their lungs.

Researchers discover new active substance effective against gram negative bacteria

More and more bacterial pathogens of infectious diseases become resistant to customary antibiotics. Typical hospital germs such as Escherichia coli and Klebsiella pneumoniae have become resistant to the most - and in some cases even all - currently available antibiotics. Their additional external membrane makes these bacteria difficult to attack.

Immunity within the lung tissue provides most protection for preventing pneumonia

Previous research has shown that recovery from bacterial pneumonia hugely improves our defense against further infections by seeding the lungs with immune cells called lung resident memory T (TRM) cells, but how these cells actually protect the lungs against future bacterial infections has been unknown until now.

Researchers design new antitumoral drug release strategy for breast cancer treatment

The local release of antitumoral drugs through bacterial proteins in the treatment of breast cancer can mark a before and after in precision medicine.

Researchers turn to older treatment methods for new health challenges

The last thing anyone wants during a stay in the hospital is a hospital-acquired infection. Nosocomial infections, as they are called, are on the rise as more pathogens become resistant to drugs currently available.

Researchers investigate a hospital outbreak in real time using high-resolution technique

On the European Antibiotic Awareness Day, researchers announce the results of a pilot study completed in record time. The initiative opens new perspectives for the control of bacterial infections in Portuguese hospitals.

Oral vaccination with cholera toxin helps counteract age-associated obesity

Here the research team tested a safe and well-established microbe-based immune adjuvant to restore immune homeostasis and counteract inflammation-associated obesity in animal models.

New database helps identify therapeutic targets to fight infectious diseases

Infectious diseases are caused by pathogenic microorganisms capable of entering, colonizing and growing within a host organism, thus producing an infection. Bacterial infections have been on the rise worldwide in recent years, but many mechanisms underlying bacterial pathogenesis are still poorly understood.

Antibiotics face an existential crisis

Antibiotics are facing an existential crisis less than a century after their introduction. The bacteria-fighting drugs are becoming less effective as a result of their overuse in both humans and animals.

'Dysbiosis' promotes the onset of colorectal cancer

The gastroenterology team at Henri-Mondor AP-HP Hospital and University Paris-Est Créteil, led by Professor Iradj Sobhani, together with teams from Inserm and the Institut Pasteur Molecular Microbial Pathogenesis Unit (U1202), led by Professor Philippe Sansonetti - holder of the Microbiology and Infectious Diseases Chair at the Collège de France -, have demonstrated that an imbalance in the gut microbiota, also known as "dysbiosis", promotes the onset of colorectal cancer.

Vaping wrecks immune cell function, increases infection risk

A new study published in the Journal of the American College of Cardiology shows that e-cigarettes have toxic effects on neutrophils function, making them a threat to human health by increasing the likelihood of infection with Gram-negative bacteria.

Researchers decode molecular structure of cytochrome bd oxidase from E. coli

Both humans and many other creatures need oxygen for survival. In the conversion of nutrients into energy, the oxygen is converted to water, for which the enzyme oxidase is responsible. It represents the last step of the so-called respiratory chain.

Short-term increases in sugar consumption could raise risk of inflammatory bowel disease

Short-term increases in sugar consumption could increase the risk of inflammatory bowel disease and have a significant impact on our health, a new study out of the University of Alberta suggests.

Researchers develop, test new blood assay that predicts patients at risk of death from sepsis

After decades of little or no progress, biomedical researchers are finally making some headway at detecting and treating sepsis, a deadly medical complication that sends a surge of pathogenic infection through the body and remains a major public health problem.

New technique enables the study of transporter proteins at a single-molecule level

Like a boat helping passengers cross a river, transporters move substances across cell membranes. This process is fundamental to the healthy functioning of cells in life forms from bacteria to humans.

Study shows potential of phage therapy to treat alcoholic liver disease

Bacteriophages (phages) are viruses that specifically destroy bacteria. In the early 20th century, researchers experimented with phages as a potential method for treating bacterial infections.

Targeting the formation of alpha-synuclein aggregates may slow Parkinson's progression

Aggregates of the protein alpha-synuclein arising in the gut may play a key role in the development of Parkinson's disease.

Caution: blood infections traced to probiotics

Probiotics aren’t harmless, says a new study published on November 7, 2019 in the journal Nature Medicine. In fact, some patients may be put at serious risk by the bacteria in probiotics. Doctors should weigh the risks of probiotics in severely ill or immunocompromised patients before prescribing them, as their benefits may be significantly smaller than the danger in such situations.
