For a long time, bacterial taxonomy was considered one of
the dullest fields in microbiology, not immediately the preferred
discipline of young or ambitious scientists. Recent developments
have changed this attitude, mainly because of the
spectacular developments witnessed in the last 10 years in the
field of sequencing of rRNA and genes coding for rRNA
(rDNA) and their contribution to bacterial phylogeny and in
molecular fingerprinting techniques. These techniques revolutionized
our insights in the phylogeny and taxonomy of all
living organisms. Taxonomy of bacteria finally also could be
assigned a place in phylogeny
