IBM says it has tool to kill deadly drug-resistant superbugs

Hospital-acquired infections have become a major killer in the United States, mainly because the drug-resistant "superbugs" that cause them have proven nearly impossible to stop.

But now IBM and the Institute of Bioengineering and Nanotechnology say they have come up with what they're calling an antimicrobial hydrogel that can successfully fight the superbugs that are behind killers like MRSA.

In an announcement today, IBM Research and its partner on the project said that their antimicrobial hydrogel was designed to cut through diseased biofilms and almost instantly kill off drug-resistant bacteria. The collaborators on the project said that … Read more

Get ready for your infections to glow in the dark

There hasn't been another major radioactive leak, but soon we could see flesh wounds glowing in the dark. Researchers at the University of Sheffield in the U.K. have developed a gel that glows under ultraviolet light when it comes in contact with many kinds of bacteria.

The gel also appears to be effective in fighting the bacteria at the same time.

"The polymers (in the gel) incorporate a fluorescent dye and are engineered to recognize and attach to bacteria, collapsing around them as they do so," Sheffield Professor Sheila MacNeil explains in a statement. "This change in polymer shape generates a fluorescent signal that we've been able to detect using a handheld UV lamp."

Project lead Dr. Steve Rimmer adds that the technology could help reduce the overuse of antibiotics. In testing, the gel has been able to detect the presence of serious bacterias including Salmonella, E. Coli, MRSA, and meningitis.… Read more

Nanoparticles may 'kick backside' of fatal bacteria

Every year, an infectious "superbug" known as MRSA kills thousands of Americans who never should have died. But an international group of scientists think they may have found the key to shutting down the lethal bacteria that leads to these deaths and to countless less-serious infections.

According to IBM Research, which worked with the Institute of Bioengineering and Nanotechnology in Singapore on the discovery of the new antibiotic nanoparticles, Methicillin-resistant Staphylococcus aureus (MRSA) killed 19,000 Americans in 2005.

This dangerous infectious bacteria is often found in hospitals and other places, like health clubs and schools, where people … Read more

Cell phones helping spread hospital superbugs?

Perhaps you, too, have friends who go nowhere without their hand sanitizer. Perhaps you, too, laugh at them beneath your clenched top lip.

However, researchers at Ondokiz Mayis University in Turkey are discovering that germs lurk everywhere. Especially in cell phones belonging to doctors and nurses, according to an Agence France Presse report. In fact, these phones may be a significant source of infections such as MRSA, which seems to have become an increasing danger in hospitals all over the world.

In researching the cell phones and dominant hands of 200 doctors and nurses, the researchers found that 95 percent … Read more
