Bergey’s manual of systematic bacteriology
by

2. Introduction
Bergey’s manual of systematic bacteriology is a manual referring to the taxonomy of
prokaryotic bacteria. It was prepared by the American bacteriologist,David Hendricks
Bergey in 1923.It is a manual that deals with the identification of bacteria.It has been
published in 9 edition.
Purpose
It provide detailed information on bacterial classification and detailed characteristics of
taxa and species.

3.  Characteristics used for classification in edition 1
• General shape and morphology
• Gram staining properties
• Oxygen relationship
• Motility
• Presence of endospores
• Mode of energy production
 The second edition of the bergey’s manual has the following volumes where it does not group
all the clinically important prokaryotes together as the 1st edition does , here the pathogenic
bacteria are placed phylogenetically, and so are distributed throughout in all volumes.

4. Edition 1 of Bergey’s manual
1. Gram(-) bacteria :section 1-11
2. Gram+ bacteria: section 12-17
3. Cyanobacteria and Archea :section 18-25
4. Actinomycetes:section 26-33

5. Gram (-) bacteria
• Includes medicinally important bacteria
• Thin peptidoglycan layer
• Outer membrane containing lipopolysaccharide
• Phototropic,chemolithotropic or chemoorgantotropic
Gram+ bacteria
• Thick peptidoglycan layer
• Chemoorganoheterotrophic
• Primarily exotoxins are produced
• Some can form endospores
• Peptidoglycan molecules are cross linked by pentaglycine chains
Archea
• They are extremophiles like methanotrophs,halophiles
• Cell wall is made of pseudomurein
• Asexual reproduction in binaryfission
• Ether bond in membrane lipids
Actinobacteria
• Anaerobes or microaerophilic
• No production of endospore
• Produce filamentous hyphae
• Important for humus formation
