Methicillin-resistant Staphylococcus aureus, (MRSA) a nasty strain of bacteria that resists most antibiotics, probably developed its defenses while spending time down on the farm, a new study says. It has been thought that humans' antibiotic abuse is the catalyst in superbug genesis, but this new research suggests it’s the animals, and the drugs we feed them, that we should worry about.
A new drug compound can recharge a class of antibiotics used to fight superbug bacteria, improving the antibiotics’ effectiveness 16-fold. It’s another volley on the part of humans in the ongoing battle between new drugs and bacterial resistance.
A new breed of biodegradable nanoparticles can glom on to drug-resistant bacteria, breaching their cell walls and leaking out their contents, selectively killing them. The polymer particles could someday be used in anything from injectable treatments for drug-resistant bacteria, to new antibacterial soaps and deodorants, according to inventors at IBM. After their work is done, the particles break apart, flushing away with the invaders they destroyed.
Cold plasma torches could be a new way to treat drug-resistant infections and heal wounds more quickly, according to new research. The plasma interferes with microbial DNA without harming human tissue, scientists say.
Sterilization is hands down one of the most important technologies ever developed by mankind, but though we’ve known how to do battle with bacterial pathogens in places like the operating room for decades, superbugs like MRSA and Clostridium difficile persist in hospital environments, often causing serious medical complications.
We don't mean to alarm you, but your home could be infested with effective, life-saving antibiotics. Research coming out of the University of Nottingham over the weekend suggests that brain tissues extracted from certain insects like cockroaches and locusts have a powerful antibiotic quality, killing more than 90 percent of Methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli without doing harm to human cells in lab tests.
Success in chess is all about anticipation -- you have to plan your moves by guessing what your opponent will do. Now scientists are taking a page from Bobby Fischer's book to fight a wily foe: drug-resistant staph bacteria, which stymies drug therapies with its swift mutation strategy. Researchers led by Bruce Donald, a professor of computer science and biochemistry at Duke University, are using a computer algorithm to predict MRSA's next move.
When Kenny George, a seven-foot center on the University of North Carolina-Asheville basketball team, recently contracted a staph infection, requiring part of his foot to be amputated, only his teammates and family blinked an eye. But when reports surfaced that Peyton Manning required knee surgery due to a similar problem, fantasy owners and the sports world took notice.
By bonding special viruses to polymers, scientists may have found an effective way to battle MRSA and more

Using living organisms to combat human disease is nothing new to medicine. The Greeks used leeches to balance the humors (didn't work). Civil war medics used maggots to clean dead tissue from wounds (did work, and is still selectively used today). The next step in fighting infection with outside help looks to come from the bacteriophages, which are viruses that only infect bacteria.
As staph infections grow stronger and more prevalent, doctors are looking beyond antibiotics

Weve been talking a lot lately about bacterial resistance to drugs, most specifically as bacteria approach the limits of our treatments of last resort. As a consequence of the diminishing returns on traditional families of antibiotics, scientists have turned their focus to more novel approaches for combating infection. The work has been aimed at better understanding the interaction between our immune system and particular bacterial strains. Most recently, a team of researchers at the University of Washington have discovered just how the common staph infection resists our defenses.
