The research highlights concerns as to the suitability of the wipes currently being deployed and the importance of a routine surveillance program in reducing risks of infection to patients.
The research, conducted by Dr. Gareth Williams at the Welsh School of Pharmacy, Cardiff University, Wales, UK, and supported by a grant from the Wales Office of research and Development for Health and Social Care (WORD), is being presented June 3, 2008 at the 108th General Meeting of the American Society for Microbiology (ASM) in Boston.
Antimicrobial-containing wipes are increasingly being used to decontaminate surfaces in hospitals. Many studies have reported on the ability of Staphylococcus aureus to contaminate and persist in the hospital environment. Germicides are commonly used on hard surfaces in hospitals to kill bacteria. The research posed the question – ‘Are we confident that these organisms are susceptible to the germicides used in our hospitals"’
The study identified the need for a test which could thoroughly examine the ability of commonly used wipes to disinfect surfaces. As such, a robust 3-step protocol to assess the ability of wipes to remove, kill and prevent the transfer of bacteria between surfaces was subsequently developed. Using the 3-step method the study examined the ability of several commercially available wipes to disinfect surfaces contaminated with Staphylococcus aureus, including Methicillin-resistant Staphylococcus aureus (MRSA).
The results showed that some wipes can remove higher numbers of bacteria from surfaces than others. However, the wipes tested were unable to kill the bacteria that they removed. As a result, they transferred high numbers of bacteria to other surfaces. Our work suggests that if these wipes encounter highly contaminated surfaces in practice, the survival of bacteria on the wipe material could lead to the cross-contamination of other surfaces if used more than once.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
