Dangerous bacteria send out warning signals when attacked by antibiotics

A bacterial infection is not just an unpleasant experience - it can also be a major health problem. Some bacteria develop resistance to otherwise effective treatment with antibiotics.

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.

Wound healing events in mucous tissues could guard against AIDS

Wound healing events in mucous tissues during early infection by Simian Immunodeficiency Virus, or SIV, guard some primate species against developing AIDS, a recent study has learned.

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.

Researchers discover why Aeromonas hydrophila can have lethal consequences in some cases

Some infections caused by bacteria can have devastating results on health. This is the case of the infections caused by Aeromonas hydrophila, which can be found in water and, if ingested orally, can sometimes cause gastrointestinal upsets that require treatment with antibiotics.

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.

Study reveals effective way to block the transmission of mosquito-borne dengue virus

An international team of scientists have reported an effective and environmentally sustainable way to block the transmission of mosquito-borne dengue virus, in trials carried out in Malaysia.

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.

Doughnut-shaped circles of ecDNA provide tumor cells with a malignant twist

Deoxyribonucleic acid or DNA encodes information, not only in its sequence but also in its shape.

ETVAX vaccine candidate shows promise against enterotoxigenic E. coli diarrhea

University of Gothenburg reports first successful results of the oral, inactivated vaccine candidate ETVAX against enterotoxigenic E. coli diarrhea in a placebo-controlled phase I/II study in infants and children from 6 months to 5 years of age in Bangladesh.

Circular DNA found in cancer cells supports their survival and resistance

A new study uncovers the role of the circular, 3D shape of extrachromosomal DNA in augmenting mutant oncogenes in cancer cells.

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.

UC Davis study identifies mechanism to rapidly repair leaky gut in monkeys with SIV infections

A UC Davis study found that the damaged gut lining (known as leaky gut) in monkeys infected with chronic simian immunodeficiency virus (SIV), an HIV-like virus, was rapidly repaired within five hours of receiving Lactobacillus plantarum bacteria.

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.
