General Systematic Bacteriology

Bacteriologists from all levels of expertise and within all specialties rely on this Manual as one of the most comprehensive and authoritative works. Since publication of the first edition of the Systematics, the field has undergone revolutionary changes, leading to a phylogenetic classification of prokaryotes based on sequencing of the small ribosomal subunit. The list of validly named species has more than doubled since publication of the first edition, and descriptions of over 2000 new and realigned species are included in this new edition along with more in-depth ecological information about individual taxa and extensive introductory essays by leading authorities in the field.

Excerpt from General Systematic Bacteriology: History, Nomenclature, Groups of Bacteria The present volume is the first of a series of monographs in the general field of systematic bacteriology. The data presented have been collected, compiled and annotated largely in connection with courses of lectures in systematic bacteriology given to graduate students dents in bacteriology at the Iowa State College during the past fif teen years. It is an attempt to bring together material which may prove of value to those who are desirous of knowing the probable nomenclatural status of the various names which have been used in bacterial terminology. If science is to be defined as a system of classified knowledge, the subject of bacteriology is laboring under a serious handicap in lack ing, probably more than any other branch of science, the advantages conferred by a satisfactory system of terminology or of nomenclature. It would seem that systematic bacteriology is deserving of even more recognition at the hands of teachers and investigators than has been accorded to it in the past. Systematic bacteriology has two principal aims or functions which are of importance to the teacher and to the investigator. The first of these aims has to do with the presentation in graphic form of our present conception of the phylogeny and of the relationships of various groups of bacteria. The second is to give a greater degree of stability to the names used for particular groups of organisms and to prevent unnecessary nomenclatural confusion in literature. These aims are thoroughly scientific, their accomplishment will prove useful, we must therefore accord them careful consideration if our nomenclature is to be stabilized.

Includes a description of the Gammaproteobacteria (1203 pages, 222 figures, and 300 tables). This large taxon includes many well known medically and environmentally important groups. Especially notable are the Enterobacteriaceae, Aeromonas, Beggiatoa, Chromatium, Legionella, Nitrococcus, Oceanospirillum, Pseudomonas, Rickettsiella, Vibrio, Xanthomonas and 155 additional genera.

One of the most authoritative works in bacterial taxonomy, this resource has been extensively revised. This five volume second edition has been reorganized along phylogenetic lines to reflect the current state of prokaryotic taxonomy. In addition to the detailed treatments provided for all of the validly named and well-known species of prokaryotes, this edition includes new ecological information and more extensive introductory chapters.

Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. A person who studies bacteriology is a bacteriologist. Bacteriological study subsequently developed a number of specializations, among which are agricultural, or soil, bacteriology; clinical diagnostic bacteriology; industrial bacteriology; marine bacteriology; public-health bacteriology; sanitary, or hygienic, bacteriology; and systematic bacteriology, which deals with taxonomy. Bacterial cells lack a membrane bound nucleus. Their genetic material is naked within the cytoplasm. Ribosomes are their only type of organelle. The term "e;nucleoid"e; refers to the region of the cytoplasm where chromosomal DNA is located, usually a singular, circular chromosome. Bacteria are usually single-celled, except when they exist in colonies. These ancestral cells reproduce by means of binary fission, duplicating their genetic material and then essentially splitting to form two daughter cells identical to the parent. A wall located outside the cell membrane provides the cell support, and protection against mechanical stress or damage from osmotic rupture and lysis. The major component of the bacterial cell wall is peptidoglycan or murein. This book is provides an excellent introduction to bacteria. In addition, it brings a first-rate general introduction to the subject for student whose courses include microbiology as a component. These include student of biochemistry, botany, zoology, medicine, pharmacy and agriculture, as well as food science, biotechnology, ecology and environmental science.
