Antibiotics are drugs used to treat infections caused by bacteria and other microorganisms.
Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife.
Trillions of microbes in the intestine aid human health, including digestion of breast milk, breaking down fiber and helping control the immune system.
Antibiotic resistance poses a grave challenge to many previously curable infectious diseases. At present, antibiotic resistance is proving to increase at a much faster rate compared to the development of new therapies.
A new study from Indiana University has revealed a previously unknown role a protein plays in helping bacteria reel in DNA in their environment -- like a fisherman pulling up a catch from the ocean.
Researchers have found a crucial enzyme in tuberculosis (TB) to target, allowing the development of new treatments to help fight against the disease's drug resistance.
The team wrote, “Feeding pets raw meat-based diets (RMBDs) has become increasingly popular but may constitute a risk due to the contamination with pathogenic and antimicrobial-resistant (AMR) bacteria.”
Scientists have uncovered a novel antibiotic-free approach that could help prevent and treat one of the most widespread bacterial pathogens, using nanocapsules made of natural ingredients.
Adapting features of the electronic medical record system used by doctors in caring for their patients may improve efforts to prevent antibiotic drug resistance, according to Penn State research.
On any given day in the United States, about 1 in 31 hospital patients has at least one health-care-associated infection, according to the Centers for Disease Control and Prevention.
The fight against global antibiotic resistance has taken a major step forward with scientists discovering a concept for fabricating nanomeshes as an effective drug delivery system for antibiotics.
Syphilis rates, like other sexually transmitted disease rates in the United States, are soaring, and the first known study to examine syphilis rates in patients with kidney failure found an incidence greater than three times that of the general population.
More than 200 square meters of our bodies -- including the digestive tract, lungs, and urinary tract -- are lined with mucus. In recent years, scientists have found some evidence that mucus is not just a physical barrier that traps bacteria and viruses, but it can also disarm pathogens and prevent them from causing infections.
Scientists have developed a new technique to trick bacteria into revealing hundreds of holes in their cell walls, opening the door for drugs that destroy bacteria’s cells.
For all the attention the human microbiome has been getting over the last few years, one aspect of such research rarely makes headlines: the difficulty of observing how it changes over time in response to various stimuli.
In adolescent and adult patients with cystic fibrosis taking lumacaftor-ivacaftor (ORKAMBI), the combination drug appears to improve lung function and body weight and reduce the need for intravenous antibiotic treatment, according to a French study published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
A new liquid-cell technology allows scientists to see biological materials and systems in three dimensions under an electron microscope (EM), according to researchers at Penn State, Virginia Tech and Protochips Inc.
An antibiotic commonly found at low concentrations in the environment can have major impacts on gut bacteria, report researchers at the University of Oregon.
The Centers for Disease Control and Prevention considers antibiotic resistance one of the most urgent public health threats, one that affects communities worldwide. The ramifications of bacteria's ability to become resistant to antibiotics can be seen in hospitals, public places, our food supply, and our water.
The growing appetite for animal protein in developing countries has resulted in a smorgasbord of antibiotic consumption for livestock that has nearly tripled the occurrence of antibiotic resistance in disease-causing bacteria easily transmitted from animals to humans, according to a recent report in the journal Science.
Antibiotic resistance is a one of the world's most pressing public health problems. Army scientists have developed a new weapon to combat super-bugs, which could protect Soldiers and fight resistance.
