TAXONOMY OF BACTERIA, BERGEY’S MANUAL OF SYSTEMATIC BACTERIOLOGY -GRAM NEGATIVE BACTERIA Srikanth H N PGS16AGR7189 Plant Pathology
4 TAXONOMY OF BACTERIA
1923 - Bergey's Manual of Determinative Bacteriology initiated It originated in the Society of American Bacteriologists (SAB) 1936 - Bergey's Manual Trust 1930 - of an International Association of Microbiological Societies ( lAMS ) 1984 - first edition of BMSB 1994 - ninth edition of BMDB 2011 second edition of BMSB 2015 - digital edition of BMSAB 5 History in brief
6 David Henricks Bergey (1860-1937)
TAXONOMY Taxonomy is the science of classification of organisms. (Greek. ‘Taxis’ – arrangement; ‘ nomos ’ – law Bacterial taxonomy consists of three separate, but interrelated areas : Classification, Nomenclature and Identification . 7
Classification is the arrangement of organisms into groups ( taxa ) on the basis of similarities or relationships. Nomenclature is the assignment of names to the taxonomic groups according to international rules International Code of Nomenclature of Bacteria The rules are maintained by ICSP Identification is the practical use of a classification scheme to determine the identity of an isolate as a member of an established taxon or as a member of a previously unidentified species. 8
Etymology Etymology means "origin and historical development of a word, "Etymology" is derived from Greek etymon means "the truth" and thus aims at the true. In principle the language of biological nomenclatural names is Latin. In nomenclature, words of Greek origin as well as those of any other origin are " latinized “ before their use 9
latinisation Is the proctice of rendering a non latin name (or word) in a latin style Latinisation is common proctice for scientific names The main purpose of latinisation may be to produce a name which is internationally consistent Ex . Escherichia : named after Theodor Escherich , who iso lated the type species of the genus. 10
TAXONOMIC RANKS Formal rank - Example Domain - Bacteria Phylum - Proteobacteria Class - Alphaproteobacteria Order - Xanthomonadales Family - Xanthomonadaceae Genus - Xanthomonas Species - axanopodis Pathovar - punicae Xanthomonas axanopodis sub sp punicae 11
BERGEY’S MANUAL 12
Compilation of known bacteria In lab , you will use the most recent edition of Bergey's Manual of Determinative Bacteriology , published in 1994 and reprinted in 2000 , to help you identify your isolates 13
Bergey’s Manual of Systematic Bacteriology The volumes are organized according to molecular classification systems including 16s rRNA sequences rather than by phenotypic characteristics Basis for classification the 'gold standard' for determining phylogenetic relationships is DNA:DNA homology by hybridization or genomic sequencing. 14
HOW IT IS ARRANGED DIVISIONS EXAMPLE Edition First, second. Volumes 1, 2, 3, 4, 5. First edn have 4 volumes Sec edn have 5 volumes Parts A, B, C, etc Vol. 2 have three parts (2A ,2B and 2C) Vol. 5 have two parts(5A and 5B) Vol.1, 3, 4, have no parts chapters Volume two, part A contain 24 chapters 15

Vol ume 4 (2011) The Bacteroidetes , Planctomycetes , Chlamydiae , spirochaetes , Fiberobacteres , Fusobacteria , Verrucomicrobia , Dictyoglomi , acidobacteria and Gemmatimonadetes . Vol ume5 (2012) The Actinobacteria (gram positive bacteria with high G+C content); 18
DETERMINATIVE vs SYSTEMATIC BERGEY’S MANUAL OF DETERMINATIVE BACTERIOLOGY BERGEY’S MANUAL OF SYSTEMATIC BACTERIOLOGY Provides identification schemes for identifying bacteria and archaea Provides phylogenetic information on bacteria and archaea Based on Morphology, differential staining, biochemical tests Based on rRNA sequencing Standard reference for laboratory identification of bacteria. Standard reference on bacterial classification 19
The organization of Bergey's Manual of Systematic Bacteriology makes it impractical for helping place unknown bacteria into major taxa , BUT it contains far more detail on the families, genera, and species and is far more up to date than the Determinative manual. 20 DRAWBACKS OF SYSTEMATIC BACTERIOLOGY
DYNAMIC TAXONOMY Lot of updates and additions About a hundred new genera and 600+ new species have been described per year for each of the last 5 years. To provide up-to-date description Bergey's Manual Trust (BMT) thought about an digital edition 21

24 Bacteria are traditionally divided into the two groups: gram-positive and gram-negative ,
GRAM NEGATIVE BACTERIA 25
26 Reviewe is conducted in association with the journal Molecular Plant Pathology according to scientific/ ecoomic importance Volume 13, Issue 6 August 2012 Pages 614–629 Rank Bacterial pathogen 1 Pseudomonas syringae pathovars 2 Ralstonia solanacearum 3 Agrobacterium tumefaciens 4 Xanthomonas oryzae pv . oryzae 5 Xanthomonas campestris pathovars 6 Xanthomonas axonopodis pv . manihotis 7 Erwinia amylovora 8 Xylella fastidiosa 9 Dickeya ( dadantii and solani ) 10 Pectobacterium carotovorum ( and P. atrosepticum )
As of January 2016, there are 30 phyla in the domain "Bacteria" accepted by LPSN . (List of Prokaryotic Names with Standing in Nomenclature ) There are no fixed rules to the nomenclature of bacterial phyla. Generally the name of the phylum is the plural of the type genus , ( ex. Fusobacteria from Fusobacterium ) With the exception of the Firmicutes , Tenericutes , Crenarchaeota , and Proteobacteria , whose names do not stem from a genus name 27
Volume 2 of the Manual covers the Proteobacteria (most gram negative bacteria) in three parts. This volume is subdivided into three parts. Part A - The Introductory Essays, Part B - The Gammaproteobacteria and Part C - The Alpha-, Beta-, Delta- and Epsilonproteobacteria . The majority of gram negatives will be found in part B. Look in part C if a description of your species is not in volume B. PLACE FOR GRAM NEGATIVE BACTERIA IN BERGEYS MANUAL 29
PROTEOBACTERIA In 1988, Stackebrandt et al . named the Proteobacteria after the Greek god Proteus, who could assume many different shapes, to reflect the enormous diversity of morphologies and physiologies observed within this bacterial phylum. 30
PROTEOBACTERIA The largest prokaryotic phylum Phenotypically most diverse phylogenetic lineage. It encompasses 74 families and includes descriptions of 425 genera and over 1875 named species . (Out of 425, I am going to mention 47 important genera) account for more than 40% of all validly published prokaryotic genera 31
CLASS I ALPHA PROTOBACTERIA 6 ORDERS ( 18 families ) PROTEOBACTERIA (G – ve bacteria) Caulobacterales Rhodospirillales Rhodobacterales Rickettsiales Rhizobiales Spingomonodales 33
