Prof. Dr. Matthias Boll from the University of Freiburg’s Faculty of Biology and his team work with Geobacter metallireducens, a bacterium that can completely degrade aromatic compounds under strictly anaerobic conditions. While the biological degradation of aromatic hydrocarbons is of global relevance, the chemical resulting from the reduction of benzene rings could also be…https://www.gesundheitsindustrie-bw.de/en/article/news/a-metal-enzyme-that-can-cleave-benzene-rings
Article - 19/10/2015 New compound that may kill hospital germs is close to clinical testing Bacteria's increasing resistance to antibiotics is a very serious medical issue. An infection with pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) bacteria can be life-threatening for hospital patients because MRSA has become resistant to the most commonly used antibiotics. Although reserve antibiotics are available in cases where others have lost their ability to control or kill bacterial growth effectively, they do not…https://www.gesundheitsindustrie-bw.de/en/article/news/new-compound-that-may-kill-hospital-germs-is-close-to-clinical-testing
Article - 17/08/2015 CDT – a bacterial toxin that mediates its own delivery into cells Clostridium difficile is totally harmless in healthy people. However, in combination with antibiotics it can cause severe diarrhoea and intestinal inflammation in elderly and debilitated people. But how does the spore-forming, rod-shaped bacterium deploy its power? And how does it enter the cell? Dr. Panagiotis Papatheodorou and his colleagues from the Institute of Experimental and Clinical Pharmacology and Toxicology (Director: Prof. Dr. Klaus…https://www.gesundheitsindustrie-bw.de/en/article/news/cdt-a-bacterial-toxin-that-mediates-its-own-delivery-into-cells

Around 75 percent of the human population lives with Candida albicans, a fungus that has no harmful effects in people with an intact immune system that can fight off systemic infections. However, in people with immune systems that have been weakened by antibiotics or radiotherapy for example C. albicans infections can lead to sepsis which may even be life-threatening.

Article - 24/11/2014 Lipid zipper triggers bacterial invasion Millions of people die each year from infections both in developing and industrial countries. There is still no effective treatment for a large number of diseases caused by pathogens. In order to treat infectious diseases effectively, we need to understand the mechanisms that bacteria use to infect human cells. The cytoskeleton of the host cell usually plays a key role in this process. Researchers at the University of Freiburg have discovered a…https://www.gesundheitsindustrie-bw.de/en/article/news/lipid-zipper-triggers-bacterial-invasion

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
Article - 02/06/2014 Researchers shed light on important metabolic pathway A research team led by microbiologist Dr. David Schleheck, in cooperation with chemists from the University of Konstanz, has discovered how sulpho-glucose is degraded in Escherichia coli bacteria.

Article - 22/04/2014 Sugar code and hygiene in the fight against multi-resistant pathogens Horizontal gene transfer between bacteria is a major reason for the spread of bacterial antibiotic resistance. It is the transfer of bacterial DNA from one bacterium to another, even distantly related species, by bacteriophages, viruses that infect bacteria. Microbiologists from the University of Tübingen are investigating these mechanisms with the aim of finding new strategies that would effectively combat bacteria such as methicillin-resistant…https://www.gesundheitsindustrie-bw.de/en/article/news/sugar-code-and-hygiene-in-the-fight-against-multi-resistant-pathogens

Article - 12/08/2013 A doorman in the bacterial membrane We are fortunate to have membranes; they separate the interior of cells from the exterior and ensure that precious substances do not leave the cell and toxic substances cannot enter. Membrane proteins do an amazing job in transporting substances from one side of the membrane to the other. This process occurs in bacteria and in humans in much the same way.
