Getting to the bottom of the burger bug

27.07.2004


Eradicating deadly E. coli O157:H7 from the bottoms of cows may prevent future outbreaks of food poisoning by this famous bug. According to an article in the August 2004 issue Microbiology Today, the quarterly magazine of the Society for General Microbiology, the majority of people with E. coli O157:H7, picked up the infection from cattle, either through direct contact with faeces or by consuming contaminated meat or milk.



Researchers at the University of Edinburgh, in collaboration with the Scottish Agricultural College and the Moredun Research Institute, were surprised to find that E. coli O157:H7 colonises only the last few centimetres of the cattle gut. As a result, bacteria are spread onto the surface of faeces as they leave the cow and can easily contaminate the environment.

“We are focused on understanding where and how E. coli O157:H7 colonises cattle”, explains Dr David Gally from the University of Edinburgh. “Our aim is to produce vaccines that stop the bacteria from attaching themselves to the gut wall. This prevents colonisation and therefore reduces the threat to human health from this dangerous pathogen.”


In the laboratory E. coli has long been associated with advancing research in cell and molecular biology and this issue of Microbiology Today explores some of the many aspects of E. coli, from the friend to the foe. Thanks to genomics, scientists now understand why some strains of E. coli are harmless, whilst others are deadly. For example, E. coli O157:H7 was made infamous due to a fatal outbreak in Scotland in 1996, whilst other strains, such as E. coli K-12, the most well studied bacterium in science, have contributed enormously to our understanding of how cells work.

Other features in the August 2004 issue of Microbiology Today include:

·Escherichia coli: model and menace (page 114)
·The history of E. coli K-12 (page 116)
·Diarrhoeal disease in the UK (page 117)
·E. coli as a probiotic (page 119)
·E. coli as an applied environmental tool (page 120)
·Comparative genomics (page 124)

These are just some of the articles that appear, together with all the regular features and reports of Society activities.

Im Focus: Carbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
