Bacterial Disease, by J.E. Partridge, University of Nebraska Lincoln, Department of Plant Pathology. Bacterial Diseases is part of an online available course in Plant Pathology. You will find diseases caused by species of Erwinia, Clavibacter, Corynebacterium, Pseudomonas, Xanthomonas, and Agrobacterium. Where appropriate you will be directed to another website, which provides the information on a special disease. On the homepage of "Introductory Plant Pathology" you will also find general information on bacteria (section #11) in Plant Pathology Concepts and Principles. This site is an outstanding educational resource on the web.

You can also read the abstracts of published papers or meet the members of the lab.
List of Bacterial Names with Standing in Nomenclature, compiled by J.P. Euzeby, Ecole Nationale Vétérinaire de Toulouse (ENVP), France. The List of Bacterial Names includes, alphabetically and chronologically, the nomenclature of bacteria as cited in the Approved Lists of Bacterial Names, or published, or validated in the International Journal of Systematic Bacteriology. It is annotated to clarify the Rules which govern the scientific nomenclature. Further available: Candidatus, a list of culture collections, definitions & abbreviations, nomenclature changes validly published and links. Candidatus is a new nomenclatural concept to record the properties of putative taxa of procaryotes which would have indefinite rank.
