Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Methicillin-resistant Staphylococcus aureus (MRSA) may soon meet its match with a new type of antimicrobial surface that kills the superbug but doesn't harm humans or animals.
MRSA, known as "golden Staph" in the UK, is resistant to antimicrobial agents commonly used and is estimated to cause 19,000 deaths and $3-4 billion (around 2-3 billion euros) in healthcare costs per year in the US. It's a looming problem in the UK as well - as of 2005, MRSA is estimated to have caused 3,000 deaths per year. The elderly, children, and people with weakened immune systems are particularly at risk, but over the past few years, there have been more and more serious outbreaks in gym locker rooms, college dormitories, and office spaces.
Scientists at the University of New Mexico in the US are working on a new type of antimicrobial surface that is inhospitable to MRSA but won't harm people or animals. They will present their results on October 21 at the science and technology-based AVS International Symposium and Exhibition in New Mexico.
The scientists developed a new polymer-type material, "conjugated polyelectrolyte," that becomes sterilized in the presence of regular fluorescent light, and has been shown effective at killing resistant strains of Staph. This opens up many potential applications, including the possibility of using these polymers as antibacterial countertops, but more work is ahead before consumers will see the product available.
The world has seen a slew of antibacterial and antibiotic products on the market over the years - soaps, socks, cutting boards, children's toys, toilet seats - most made with agents triclosan and tributyletin. More recently, antimicrobial silver ions have been manufactured into everything from washing machines to deodorant to repel bacteria. However, health and environmental concerns linger over whether or not the widespread usage of antibacterial products is strengthening the resistance of superbugs such as MRSA.
What are some practical ways of preventing an MRSA infection? The prestigious US-based Mayo Clinic suggests washing your hands for at least 15 seconds or using a hand sanitizer when you don't have access to soap and water. Also, be sure to keep wounds covered, and avoid sharing personal items, such as razors or towels. Shower with soap and water after athletic games, and sanitize linens if you have a cut or sore.
