Antibiotics alter the normal bacterial flora in humans

17.03.2004


Microbes researchers highlight drawbacks of antibiotics



Bacteria that are resistant to antibiotics can live in the human intestines for at least one year. Professor Charlotta Edlund from the Karolinska Institutet in Stockholm, Sweden, and Research Professor Pentti Huovinen from the National Public Health Institute in Turku, Finland, are keen to highlight the risks involved in the excessive use of antibiotics.

In their research funded by the Academy of Finland, the two professors are exploring the long-term impacts of antibiotic treatment on the bacterial flora in human intestines. At the same time, they are looking to develop new research methods for studying intestinal bacterial flora. The project is part of the Academy’s Microbes and Man research programme, a joint effort among researchers from Finland and Sweden.


Antibiotic-resistant bacteria are one of the most serious threats to health care. Earlier it has been assumed that the effects of antibiotics disappear within a couple of months and that the intestinal bacterial flora is then restored to normal. Researchers believe that antibiotics also have characteristics which maintain and promote the health of the bacterial flora.

It has now been shown that the antibiotic studied, i.e. clindamycine, continues to have a clearly visible impact up to one year after treatment is discontinued. Even more surprisingly, it has been found that resistance also increases to other antibiotics, such as penicillins, tetracyclines, and macrolides. In other words, the use of one type of antibiotic simultaneously increases resistance to several other antibiotics.

The focus of research at the Karolinska Institutet in Stockholm is upon intestinal anaerobic bacteria that have poor tolerance of oxygen, while researchers at the National Public Health Institute in Turku are studying aerobic bacteria, which also grow in the presence of oxygen.

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...
