Tetracycline is an antibiotic drug used to treat infection.
UNC School of Medicine scientists created a powerful new "directed evolution" technique for the rapid development of scientific tools and new treatments for many diseases.
A scientific team from Case Western Reserve University School of Medicine and Cleveland Clinic has developed a new way to identify second-line antibiotics that may be effective in killing germs already resistant to a first-line antibiotic - potentially helping overcome antibiotic resistance.
Face masks appear to provide important protection against drug-resistant Staphylococcus aureus bacteria for hog farm workers and for household members to whom they might otherwise transmit the bacteria, according to a study led by scientists at Johns Hopkins Bloomberg School of Public Health.
The bite from a brown recluse spider (Loxosceles) can cause skin necrosis, renal failure, and even death. A new ointment is being tested in Brazil, however. Its effects have already been proven in tests conducted in cell cultures and animal models.
Salad is popular with people who want to maintain a balanced and healthy diet. Salad varieties are often offered for sale ready-cut and film-packaged. It is known that these types of fresh produce may be contaminated with bacteria that are relevant from the point of view of hygiene.
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.
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.
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.
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.
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 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.
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.
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.
Genes do not exist in isolation. Like beads on a string, they sit next to each other on long DNA molecules called chromosomes.
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.
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.
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.
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.
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.
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
