Press release - 09/10/2012 Bacterium in a Laser Trap Scientists from the Department of Microsystems Engineering IMTEK of the University of Freiburg have constructed an innovative new optical trap that can grab and scan tiny elongated bacteria with the help of a laser. Optical tweezers could previously only be used to grab bacteria at one point not to manipulate their orientation.

Article - 06/07/2014 Behaviour-changing signalling molecules as alternative to antibiotics Bacteria display group behaviours when they form biofilms or cause infections. These group behaviours protect them against adverse environmental conditions. Thomas Böttcher from the University of Konstanz studies the signalling molecules that control this behaviour. His work involves identifying and characterising natural substances that can prevent bacteria from forming biofilms and from swarming. The substances’ medically relevant effect makes…https://www.gesundheitsindustrie-bw.de/en/article/news/behaviour-changing-signalling-molecules-as-alternative-to-antibiotics

Dossier - 30/08/2010 Disease prevention through better diagnostics “Classical treatment approaches are not the only way to ensure good health, rehabilitation and care. In fact, it is envisaged that more effective prevention will contribute to halting the development of diseases and maintaining good health. Prevention is designed to prevent health risks and diseases, make them less likely and delay their onset.” (Declaration of the German government; Official Records of Parliament 17/845, 26th February 2010) https://www.gesundheitsindustrie-bw.de/en/article/dossier/disease-prevention-through-better-diagnostics
Press release - 30/03/2011 Bacteria poison themselves from within The research group led by Anton Meinhart at the Max Planck Institute for Medical Research in Heidelberg has shown that proteins from the zeta toxin group trigger a self-destructive mechanism in bacteria. The triggers for this bacterial suicide are toxin/antitoxin systems that play an important role in the hereditary transmission of resistance and virulence genes. The scientists have thus found a valuable new tool for the development of new…https://www.gesundheitsindustrie-bw.de/en/article/press-release/bacteria-poison-themselves-from-within

Article - 23/05/2018 Bacteriophages as alternatives to antibiotics Multidrug-resistant bacteria are resistant to many existing antibiotics and can be difficult to treat. There are increasing numbers of them worldwide. Although novel antibiotics are being developed, there are far too few of them to tackle the rise of multidrug-resistant bacteria. In Eastern Europe, doctors have been treating bacterial infections with viruses that infect bacteria, so-called bacteriophages, for almost 100 years.https://www.gesundheitsindustrie-bw.de/en/article/news/bacteriophages-as-alternatives-to-antibiotics

Press release - 21/04/2011 Scientists describe temperature compensation mechanism in bacteria Temperature fluctuations have an adverse effect on most living organisms. Mammals and birds have intricate systems to keep their body temperatures constant. Though primitive coliform bacteria do not possess such systems, they still manage to offset these fluctuations.
