Microbiology TodayNovember 2006 - Systematics


Being small and abundant has led to many problems with the classification of micro-organisms. This issue of Microbiology Today looks at microbial systematics.

'Species'
Genome sequence data are raising questions over the definition of bacterial 'species', as W. Ford Doolittle explains.

Taxonomic parameters revisited: tarnished gold standards
Erko Stackebrandt and Jonas Ebers describe how molecular standards used to characterize species are outdated and may require re-defining.

Virus systematics: taxonomy for the tiny
A host of factors complicate the classification of viruses. Anne-Lise Haenni and Mike Mayo explain how internationally agreed standards help virus systematics.

How many yeasts?
Meredith Blackwell tells us where to start when classifying novel yeasts.

Protozoa: the most abundant predators on earth
After decades of radical reform, protozoan systematics has reached a consensus, as Thomas Cavalier-Smith explains.

Disentangling the trails of evolution
Phylogenetic trees are making analysis of the abundance of new sequence data possible. Gemma Atkinson and Sandra Baldauf provide a guide to phylogenies.

Comment: MicrobiologyBytes
Alan Cann tells us why he thinks that new media are the future for microbiology education.

Schoolzone
John Grainger, Janet Hurst and Jane Westwell review a number of recent educational resources about health and disease.

Gradline
Jane Westwell takes a look at research and development in the biopharmaceutical industry.

Hot off the Press highlights some new developments in microbiological research published in the Society's journals - Microbiology, Journal of General Virology, International Journal of Systematic and Evolutionary Microbiology and Journal of Medical Microbiology. Topics covered include:

  • New approach to TB control using granulysin
  • SARS in horseshoe bats
  • Microdiesel from E. coli - an alternative to fossil fuels?
  • Novel yeast distribution in insects
