News: Livestock Antibiotic Use Increases Threat of Resistant Microbes to Humans
Antibiotics used to prevent diseases in livestock are creating a world of hurt for humans and the soil we depend on for food. Bacterial resistance to antibiotics is a global health issue. The overuse, underuse, and poor use of these life-saving drugs is rapidly removing them as a treatment option for serious infections in humans—plus bacteria are naturally adaptive.
News: 'Useless' Antibiotics Work When Matched Up in Threes
The search is on to find antibiotics that will work against superbugs — bacteria that are rapidly becoming resistant to many drugs in our antibiotic arsenal.
Step Aside MRSA & C Diff: Researchers Just Found 3 New Healthcare Associated Infections
The growing list of dangerous antibiotic resistant organisms has just acquired three new members. Researchers have discovered three new species of Klebsiella bacteria, all of which can cause life-threatening infections and have genes that make them resistant to commonly used antibiotics.
News: A Compound from This Florida Weed Could Kill Deadly MRSA Staph Infections
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.
News: A Protein Found in Ticks Can Help Kill MRSA Infections
As researchers from Yale searched our environment for compounds to aid in the battle against drug-resistant bacteria, they got an unlikely assist from ticks.
News: 4 Billion Year Old 'Fossil' Genes May Be Our Secret Weapon Against Infection
The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.
Synthetic Biology: Student Team Gives Dangerous E. Coli a New Role as Bacteria Detective
A gold-medal winning entry into the iGEM synthetic biology competition could change the way we look at Esherichia coli, the bacteria better known as E. coli.
News: Unique Way Gonorrhea Breaks Down the Female Body's Defenses
Usually, the mucus lining of the female genital tract presents a barrier that helps prevent infections. But, somehow, the bacteria that causes gonorrhea gets around and through that barrier to invade the female genital tract.
News: New Research Shows How Flesh-Eating Leishmania Parasites Hide in Our Bodies to Fight Future Infections
Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year. Two new studies offer understanding of how the parasite provides immunity through persistence and why some people suffer more virulent forms of the disease.
News: 'Vampire' Bacteria May Lead Fight Against Antibiotic Resistance
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
Amazing Insects: Ants Create Chemical Cocktails to Brew Antibiotics
To keep fungal pathogens at bay in their crowded homes, wood ants mix potions to create powerful protection for their nest and their young.
News: How Calcium Sets Off a C Diff Infection
Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
News: New Research Makes Detecting Flu as Easy as a Pregnancy Test
Could your fever, body aches, cough, and sore throat be the flu? Soon, finding out may not involve a trip to the doctor.
Natural Solution: Extract Synthesized from Maple Syrup Boosts Efficiency of Antibiotics
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
News: The Next Magic Bullet Antibiotic May Come from Roadkill
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
Lucky Break: Pneumococcal Vaccine Fights Off Ear Infections, Too
More prescriptions for antibiotics are written for ear infections than any other type of infection. A new study comparing the incidence and causes of ear infections in children between the ages of six months and three years found that the incidence of ear infections over the last decade has dropped significantly since the 1980s.
Double Shot: New Class of Antibiotics Could Treat Plague & Multi-Drug Resistant Superinfections
Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to hit a well known bacterial target and have developed a drug to hit it.
News: New 'Trojan Horse' Salmonella Bacteria Kills Tumors Instead of Making You Sick
We usually associate Salmonella bacteria with a dangerous type of food poisoning, but they actually are pretty good at seeking out tumors. That trait made the bacteria a great candidate to deliver a protein that would help knock tumors out.
News: The Next Big Antibiotic Could Come from the Gut of an Insect
No one can dispute the evolutionary success of bugs. The oldest insect fossils were found encased in crystallized mineral silica in Scotland in 1926, and they're between 396 and 407 million years old.
News: Common Soil Microbe Produces New Antibiotic Effective Against Resistant Bacteria
Significant strides have been in the race to find antibiotics to treat superbug infections — those caused by bacteria resistant to the antibiotics used to treat them. Now, an international team of scientists has discovered a new antibiotic produced by a microbe found in Italian soil.
