When your doctor prescribes an antibiotic, there's a 43% chance it may not be needed, a new study finds.
"While there has been a lot of research looking at inappropriate prescribing, our findings suggest that we still may be underestimating the proportion of prescriptions that are inappropriate," said lead study author Michael Ray, a researcher at Oregon State University College ...
Millions of Americans think they're allergic to penicillin, but they're not, a new study reveals.
This erroneous belief adds millions of dollars to health care costs and results in unnecessary side effects from more powerful antibiotics, researchers say. It also adds to the danger of creating antibiotic-resistant bacteria, they warn.
Taking certain antibiotics -- especially multiple times or for long courses -- may put you at risk for colon cancer, a large new study suggests.
The researchers found that as people's antibiotic use increased, their odds of being diagnosed with colon cancer inched up. Specifically, the risk was tied to antibiotics that kill anaerobic bacteria -- which include common drugs like penicil...
Most Americans consider antibiotic resistance a threat to public health, but 45% say they've used antibiotics improperly, a new poll reports.
Of those, 39% did not finish a course of antibiotics and 16% took them without talking first to a health care provider, according to a phone poll of more than 1,200 adults nationwide by the Henry J. Kaiser Family Foundation (KFF).
Dentists tend to be overeager when it comes to prescribing antibiotics, new research suggests.
The study authors found that antibiotics prescribed to prevent infection during dental procedures weren't necessary 81% of the time. That's important because 10% of all antibiotic prescriptions come from dentists, the researchers said.
"Superbugs" strike fear in the hearts of scientists who are racing to find new drugs to fight these dangerous infections, but British researchers now report they have developed a compound that could battle these antibiotic-resistant bacteria in an entirely new way.
The compound, a metal complex based on the element ruthenium, "works by binding to the cell wall of bacteria and disrupti...
Viruses and bacteria are the culprits behind the infectious diseases that plague humans. Researchers recently turned one against the other, using viruses to wipe out a potentially life-threatening bacterium in a 15-year-old girl with cystic fibrosis.
This old-time approach to battling bacterial infections might be worth another look in these days of antibiotic-resistant bacteria, a ne...
Privacy curtains in hospital rooms might offer patients some personal dignity, but they can also harbor dangerous, drug-resistant bacteria.
That's the claim of a new study where researchers took more than 1,500 samples from privacy curtains in 625 rooms at six skilled nursing facilities in Michigan. The samples were collected from the parts of the curtains touched most often. Samples...
Experts are sounding the alarm about a cluster of four New York City hospital patients carrying an antibiotic-resistant "superbug" form of E. coli.
The E. coli harbored by the patients has an antibiotic resistance gene called mcr-1, which gives the bacteria resistance to colistin, an antibiotic of last resort against some multidrug-resistant infections, according to a team led by Dr. ...
Scientists are looking to an unexpected source in the battle against drug-resistant bacteria: fish slime.
The researchers said that microbes in the protective mucus that coats young fish holds promise in fighting multidrug-resistant bacteria. These include the so-called "superbug" microbes that cause methicillin-resistant Staphylococcus aureus (MRSA) infections.
An antibacterial called triclosan is common in dust and could result in dust-dwelling bacteria becoming antibiotic-resistant, researchers report.
"There is this conventional wisdom that says everything that's in dust is dead, but that's not actually the case. There are things living in there," said study leader Erica Hartmann, an assistant professor of environmental engineering at Nor...
A majority of Americans believe the health threat posed by antibiotic resistance is real and pressing, a new survey shows.
The survey of more than 1,000 adults found that 65 percent believe antibiotic resistance is a public health problem, and 81 percent are worried that antibiotic resistance will make more infections difficult to treat or even deadly.
If your urinary tract infection isn't responding to antibiotics, you could be headed for a fast relapse, researchers say.
In a new study of 151 adults with antibiotic-resistant UTIs, investigators found that these patients were more likely to have a relapse within a week and were more likely to be prescribed an incorrect antibiotic than a comparison group of patients with non-resista...
An "alarming" number of American parents save unused antibiotics and give them to family members and other people, a new study finds.
This type of misuse helps fuel antibiotic resistance, the study authors said. Their report is scheduled for presentation Monday in Orlando, Fla., at the national conference of the American Academy of Pediatrics (AAP).
After years of public health warnings about antibiotic misuse, a new study suggests the problem is far from being solved.
Researchers found that of more than 500,000 antibiotic prescriptions they analyzed, nearly half were written without an infection-related diagnosis. And about 20 percent were given without an office visit -- usually over the phone.
If you're suffering from acute appendicitis, you might be successfully treated with antibiotics and never need an operation to remove your appendix, Finnish researchers report.
Most appendicitis cases are uncomplicated, which simply means the organ hasn't ruptured, so they can be treated with antibiotics. Only when the appendix looks like it may burst immediately is an operation neces...
Tuberculosis remains the most lethal of infectious diseases worldwide, killing more than 1.6 million people a year. But researchers say a new vaccine might prevent half of full-blown illnesses in infected people who receive the shot.
"We found that the incidence of pulmonary tuberculosis was significantly lower" for people who got the experimental vaccine, called M72/AS01, than for pe...
