Bergey's Manual of Determinative Bacteriology: A Key for the Identification of Organisms of the Class Schizomycetes

There have been numerous attempts to arrange the species of bacteria in natural systems of classification. The first simple system of Müller listed but two genera (Vibrio and Monas), which included organisms that would today probably be accepted as bacteria. The present manual was first published sixteen years ago. The first edition contained tabulated descriptions of 832 species of bacteria, while the present edition contains descriptions of 1,335 species with a reference to the original place of publication of 5,600 descriptions..The increase in number is due chiefly to the recognition of groups of genera which seem to be related to one another yet distinct from other groups. Nine new generic names are used: Noguchia, Microbacterium, Fusobacterium, Pasteuria, Caulobacter, Proactinomyces, Malleomyces, Veillonella and Blastocaulis. In spite of the extensive rearrangement of genera and the use of nine new generic terms, few new binominals have been formed and no trinominals are used.
