Five patients suffered from infection including bacteremia, lower respiratory tract infection and urinary tract infection associated with the bacterial outbreak in August 2006. Skin care products sold in the European Union are not required to be sterile, but there are limits to the amount and type of bacteria that are permitted.
The Hospital Universitari del Mar, Universitat Autònoma de Barcelona’s routine infection control surveillance pinpointed the unwelcome bacteria in five patients’ biological samples. Researchers tested a number of environmental samples, and discovered that moisturizing body milk used in the patients’ care was a B. cepacia reservoir. Pulsed-field gel electrophoresis experiments confirmed that all of the strains of B. cepacia bacteria found in-patient and environmental samples were from the same bacterial clone. Tests on sealed containers of the moisturizer confirmed that the bacteria had not invaded the product after it had been opened, but that it was contaminated during manufacturing, transportation or storage.
“This outbreak of nosocomial infection caused by B. cepacia in five severely ill patients supports a strong recommendation against the use cosmetic products for which there is no guarantee of sterilization during the manufacturing process,” says study author Francisco Álvarez-Lerma.
B. cepacia is a group or “complex” of bacteria that can be found in soil and water. They have a high resistance to numerous antimicrobials and antiseptics and are characterised by the capacity to survive in a large variety of hospital microenvironments These bugs pose little medical risk to healthy people. However, those with weakened immune systems or chronic lung diseases, particularly cystic fibrosis, may be more susceptible to B. cepacia infection. B cepacia is a known cause of hospital infections.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
