Staphylococcus aureus News and Research RSS Feed - Staphylococcus aureus News and Research

Staphylococcus aureus is a spherical bacterium (coccus) which on microscopic examination appears in pairs, short chains, or bunched, grape-like clusters. These organisms are Gram-positive. Some strains are capable of producing a highly heat-stable protein toxin that causes illness in humans.

Tannic acid may help ease impact of bacterial lung infections in CF patients

By screening over 2,000 approved drugs and natural products, scientists have shown that tannic acid may help ease the impact of bacterial lung infections in cystic fibrosis patients. [More]
Vancomycin drug still effective in treating Staphylococcus aureus bloodstream infections

Vancomycin drug still effective in treating Staphylococcus aureus bloodstream infections

A University of Nebraska Medical Center research team has determined that a longtime antibiotic, vancomycin, is still effective in treating Staphylococcus aureus bloodstream infections and that physicians should continue to use the drug even though several newer antibiotics are now available in the marketplace.

Study suggests that college athletes who play contact sports more likely to carry MRSA

Study suggests that college athletes who play contact sports more likely to carry MRSA

Even if they don't show signs of infection, college athletes who play football, soccer and other contact sports are more likely to carry the superbug methicillin-resistant Staphylococcus aureus (MRSA), suggests a study on MRSA and athletes, which is being presented at IDWeek 2014-. [More]
Columbia Nursing researcher suggests ways to prevent nursing home infections

Columbia Nursing researcher suggests ways to prevent nursing home infections

Nursing home infection rates are on the rise, a study from Columbia University School of Nursing found, suggesting that more must be done to protect residents of these facilities from preventable complications. The study, which examined infections in U.S. nursing homes over a five-year period, found increased infection rates for pneumonia, urinary tract infections (UTIs), viral hepatitis, septicemia, wound infections, and multiple drug-resistant organisms (MDROs).

FDA grants QIDP and Fast Track designation to Nabriva's lefamulin for treatment of CABP, ABSSSI

Nabriva Therapeutics AG, a biotechnology company focused on developing pleuromutilins, a new class of antibiotics for the treatment of serious infections caused by resistant Gram-positive and Gram-negative pathogens, announced today that the United States Food and Drug Administration has granted Qualified Infectious Disease Product (QIDP) as well as Fast Track status designation to Nabriva's lead product lefamulin, for the treatment of community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI).

Universal MRSA screening may be too costly for individual hospital to adopt

Universal MRSA screening may be too costly for individual hospital to adopt

Numerous experts and policy makers have called for hospitals to screen patients for methicillin-resistant Staphylococcus aureus (MRSA) infections and isolate anyone testing positive to prevent the spread of these so-called "Superbugs" in healthcare settings. [More]
LLNL scientists issued patent for producing antimicrobial compounds to fight superbugs

LLNL scientists issued patent for producing antimicrobial compounds to fight superbugs

Superbugs, antibiotic-resistant bacteria, have been on the rise since antibiotics were first introduced 80 years ago. That's because these germ-fighting agents have lost their punch from being overprescribed and misused, allowing bacteria pathogens to develop immunities against them. [More]
Study finds that hospitalized patients wash their hands infrequently

Study finds that hospitalized patients wash their hands infrequently

Hospital visitors and staff are greeted with hand sanitizer dispensers in the lobby, by the elevators and outside rooms as reminders to wash their hands to stop infections, but just how clean are patients' hands? [More]

TRU-D SmartUVC’s Ebola-killing UVC automated disinfection robot to be showcased at IDWeek 2014

TRU-D SmartUVC LLC will feature its Ebola-killing UVC automated disinfection robot at IDWeek 2014 in Philadelphia this week from October 8 to 12 at booth 826. [More]
Researchers reveal 'programmable' antibiotic technique to target drug-resistant microbes

Researchers reveal 'programmable' antibiotic technique to target drug-resistant microbes

The multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating brute force of traditional antibiotics, which wipe out everything at once, regardless of the consequences. [More]
MIT engineers find new strategy to combat superbugs

MIT engineers find new strategy to combat superbugs

In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect more than 2 million people nationwide, and kill at least 23,000. Despite the urgent need for new treatments, scientists have discovered very few new classes of antibiotics in the past decade. [More]
TSRI scientists devise new vancomycin-based antibiotic to rout resistant bacteria

TSRI scientists devise new vancomycin-based antibiotic to rout resistant bacteria

Scientists at The Scripps Research Institute have devised a new antibiotic based on vancomycin that is powerfully effective against vancomycin-resistant strains of MRSA and other disease-causing bacteria. [More]

American Biotech launches new silver hydrogel wound-dressing products

American Biotech Labs, LLC, is pleased to announce the availability of three new silver hydrogel wound-dressing products. [More]
Bacteria in fresh honey produce myriad of active antimicrobial compounds

Bacteria in fresh honey produce myriad of active antimicrobial compounds

Raw honey has been used against infections for millennia, before honey - as we now know it - was manufactured and sold in stores. So what is the key to its' antimicrobial properties? Researchers at Lund University in Sweden have identified a unique group of 13 lactic acid bacteria found in fresh honey, from the honey stomach of bees. [More]

Nearly half of hog workers carry livestock-associated bacteria to home

A new study suggests that nearly half of workers who care for animals in large industrial hog farming operations may be carrying home livestock-associated bacteria in their noses, and that this potentially harmful bacteria remains with them up to four days after exposure. [More]
Antibiotic stewardship programs reduce hospital readmissions due to infection

Antibiotic stewardship programs reduce hospital readmissions due to infection

Antibiotic stewardship programs, which promote the appropriate use of antibiotics in hospitals and other healthcare centers, not only lead to reduction in antibiotic use with reduced adverse events, but also lead to significant savings. [More]
