The sixth edition has been extensively updated; much of the text is new, or re-written, and there are many new references. Over 70 genera of bacteria, listed alphabetically, are described in the Appendix. Cross-references and a detailed index, maximise the accessibility of data.
Reviews of previous editions:
"....a useful survey of the subject for students contemplating specialization."
--Nature
"Singleton assumes the reader has no prior knowledge of DNA and gene expression, and does an extraordinary job of explaining things from scratch."
--Quarterly Review of Biology
"....recommended to undergraduates and those seeking clear explanations of basic concepts of bacteriology."
--Journal of Medical Microbiology
