Hospital bugs get from bottom to bedrail

13.09.2007
The presence of the bacterium Staphylococcus aureus (S. aureus) in patients’ stools increases the likelihood that it will make its way onto skin, hospital bed rails and other surfaces, according to research published in the online open access journal, BMC Infectious Diseases.

Curtis Donskey and colleagues from the Cleveland Veterans Affairs Medical Center, Ohio, US, collected stool samples from inpatients and analysed these for S. aureus. The researchers also took samples from the patients’ nostrils, armpits and groins, as well as surrounding surfaces such as bed rails and bedside tables using a moist cotton swab. To determine whether these bacteria would be transferred to the researchers’ hands they bravely touched each of the skin and environmental sites with one hand previously disinfected with an alcohol hand rub. Handprints in agar jelly before and after testing were used to determine the presence of bacterial transfer.

The study’s most important finding was that patients harbouring S. aureus in both their intestines and noses were significantly more likely than those with this bacterium in their nostrils alone to have positive skin cultures. There was also a statistically non-significant trend toward contaminating surrounding surfaces and bacterial transfer to the investigator’s hands.

Cultures from environmental surfaces yielded an average of 12.7 colonies with a range of 1 to 80, while cultures from armpits and groins yielded colonies of bacteria “too numerous to count.” Hand cultures after contact with environmental and skin surfaces yielded an average of 15.3 colonies with a range of 1 to 80. Most of the patients colonized with S. aureus had the MRSA (Methicillin-resistant Staphylococcus aureus) strain, which is unaffected by treatment with certain antibiotics.

“Because staphylococci on skin may contaminate devices or wounds and be acquired on hands, our data provide support for the hypothesis that colonization of the intestinal tract may facilitate S. aureus infections and nosocomial transmission,” Donskey says.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
