Tetracycline is an antibiotic drug used to treat infection.

Common bacteria that cause foodborne diseases found to be resistant to antibiotics

Brazil's Ministry of Health received reports of 11,524 outbreaks of foodborne diseases between 2000 and 2015, with 219,909 individuals falling sick and 167 dying from the diseases in question.

Researchers track where tetracycline antibiotics go in human cells

We know that antibiotics treat bacterial infections. We also know why they work. Tetracycline antibiotics, for example, stop bacteria from making protein. Like a boot on a wheel, the drugs bind to the bacterial cell's ribosome--where protein is made--and prevent it from working. Without protein, the bacteria weaken and die.

Study highlights hidden hazards of airborne antibiotic-resistance genes

People are often notified about poor air quality by weather apps, and this happens frequently in urban areas, where levels of outdoor pollution containing particulates and soot are high.

Diuretic drug may be just as effective as oral antibiotics to treat acne in female patients

In a finding that suggests the potential for practice change that would reduce the use of antibiotics in dermatology, researchers in the Perelman School of Medicine at the University of Pennsylvania have found the diuretic drug spironolactone may be just as effective as antibiotics for the treatment of women's acne.

Farm waste may be contributing to spread of antibiotic-resistant bacteria

Each year, farmers in the U.S. purchase tens of millions of pounds of antibiotics that are approved for use in cows, pigs, fowl and other livestock.

Bacteria in humans and animals continue to show high levels of antimicrobial resistance

Bacteria from humans and animals continue to show resistance to antimicrobials, according to a new report published today by the European Food Safety Authority and the European Centre for Disease Prevention and Control.

Detailed phenotypic information on resistance genes can guide future drug development

The genes that are able to equip bacteria with resistance to clinically used antibiotics have been found in many different natural environments. Nevertheless, a functional overview of the resistance genes found in common human bacterial pathogens has been missing so far.

FDA approves first medical device system that can make adjustments to implanted lens after cataract surgery

The U.S. Food and Drug Administration today approved the RxSight Inc. Light Adjustable Lens and Light Delivery Device, the first medical device system that can make small adjustments to the artificial lens' power after cataract surgery so that the patient will have better vision when not using glasses.

Gene's position on chromosome influences mutations, study shows

Genes do not exist in isolation. Like beads on a string, they sit next to each other on long DNA molecules called chromosomes.

Harris Health System expert offers guidance to prevent drug-induced photosensitivity

Wanting a tan or simply enjoying the outdoors during the summer can expose skin to the effects of ultraviolet rays- a problem complicated for people taking certain medications, warns a Harris Health System expert.

Study finds increasing susceptibility of Staphylococcus aureus in U.S. hospital patients

Findings from a study that looked at susceptibility trends of Staphylococcus aureus in U.S. hospital patients showed that key antibiotics used to treat the bacteria became more active over the course of the study, a rare occurrence.

Study: Antibiotic therapy does not work for nearly one in four adults with community-acquired pneumonia

Approximately one in four (22.1 percent) adults prescribed an antibiotic in an outpatient setting (such as a doctor's office) for community-acquired pneumonia does not respond to treatment, according to a new study presented at the 2017 American Thoracic Society International Conference.

Innovative ways to target antibiotic resistance in short term

There has been much recent talk about how to target the rising tide of antibiotic resistance across the world, one of the biggest threats to global health today.

Researchers develop biosensor system that can detect different antibiotics in human blood

A team of researchers from the University of Freiburg has developed a system inspired by biology that can detect several different antibiotics in human blood or other fluids at the same time.

Scientists develop new optical fiber-based probe for brain temperature measurements

The brain is the most temperature-sensitive organ in the body. Even small deviations in brain temperature are capable of producing profound effects--including behavioral changes, cell toxicity, and neuronal cell death. The problem faced by researchers and clinicians is how to measure and understand the

Antibiotic usage, infections may contribute to manic episodes in people with mental disorders

In research using patient medical records, investigators from Johns Hopkins and Sheppard Pratt Health System report that people with serious mental disorders who were hospitalized for mania were more likely to be on antibiotics to treat active infections than a group of people without a mental disorder.

Tiny molecular scaffolding could be key to fight against antibiotic resistance

Tiny molecular scaffolding that joins molecules together could be the key to our battle against antibiotic resistance. Research published in Bioorganic & Medicinal Chemistry Letters shows that carbon nanodot scaffolding assembled with small molecules called polyamines can kill some dangerous drug-resistant bacteria, including Acinetobacter baumanii and Klebsiella pneumonia.

Rosacea linked to Parkinson's disease risk

Data from a nationwide study show that people with the skin condition rosacea are at an increased risk of later developing Parkinson's disease.

Researchers describe antibiotic resistance as either selfish or co-operative

Trace concentrations of antibiotic, such as those found in sewage outfalls, are enough to enable bacteria to keep antibiotic resistance, new research from the University of York has found. The concentrations are much lower than previously anticipated, and help to explain why antibiotic resistance is so persistent in the environment.

UAB research reveals heterogonous population of leukemia stem cells

University of Alabama at Birmingham researchers have found a marker on blood cells that may help the most pressing problem in chronic myelogenous leukemia, or CML, today — an inability to get patients off treatment.
