The plenary session is entitled Food, fluids, fingers, faeces and flies: food and waterborne pathogens and includes some fascinating presentations.
Hepatitis E virus (HEV), which can be fatal, was thought to be confined to China, India and developing countries but scientists in the Netherlands have found that people in European countries are contracting the virus from pork. It is one of few viruses that can be transmitted directly from the animal to humans through food. Doctors rarely test for HEV and it is estimated that diagnosis rates in Europe are only 13%.
And it’s not just pork that’s being studied. There has been a rise in year-round consumption of lettuce, which is coupled with a rise in the difficulty of keeping it pathogen-free. Although processing and packaging were suspected as sources of contamination, US scientists have shown that at least some cases of food poisoning are due to contamination prior to harvesting. Complex environmental factors make this very difficult to control.
Cutting-edge research will also be revealed in the session Anaerobe 2007: Changing perceptions and patterns of anaerobic infection. Hospital superbug C. difficile has a coat of armour that can self-assemble even when it’s taken off the bacterium. The protein coat has a regular shape and joins together itself. This could give scientists at Imperial College London a way of fighting the superbug, by identifying a glitch in the armour. It even has commercial applications in nanotechnology.
Anaerobes also have clinical applications. Solid tumours have areas of low oxygen, so anaerobic bacteria are ideal to deliver gene therapy to these areas. Clostridium can form oxygen resistant spores and grow when it enters a low oxygen environment, like a tumour. Scientists have shown that genetically engineered Clostridium can treat cancer successfully in mice.
Other presentations cover topics as diverse as ham preservation and why we don’t need salt, probiotics for pigs and bacterial pest control, tracking Yersinia and microbe-identifying microchips, novel insecticides and drug-producing sponge bacteria, hepatitis C vaccine research, bacteriophage therapy and the control of coastal pollution.
Individual press releases for all of the above presentations are available. Please contact SGM if you are interested in attending the meeting, or if you would like to speak to one of our experts.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
