Bacterial taxonomy is the classification of strains within the domain Bacteria into hierarchies of similarity. This classification is similar to that of plants , mammals , and other taxonomies. However, biologists specializing in different areas have developed differing taxonomic conventions over time.
Bergey's Manual Trust was established in 1936 to sustain the publication of Bergey's Manual of Determinative Bacteriology and supplementary reference works. The Trust also recognizes individuals who have made outstanding contributions to bacterial taxonomy by presentation of the Bergey Award and Bergey Medal, jointly supported by funds from the Trust and from Springer, the publishers of the ...
There are several models of the branching order of bacterial phyla, one of these is the Genome Taxonomy Database (GTDB). The GTDB is an initiative to establish a standardised microbial taxonomy based on genome phylogeny, primarily funded by an Australian Research Council Laureate Fellowship.
DNA–DNA hybridization (DDH) is used as a primary method to distinguish bacterial species as it is difficult to visually classify them accurately. [7] This technique is not widely used on larger organisms where differences in species are easier to identify.
The genomes used to construct the phylogeny are obtained from NCBI (RefSeq and Genbank), and GTDB releases are indexed to RefSeq releases, starting with release 76.. Importantly and increasingly, this dataset includes draft genomes of uncultured microorganisms obtained from metagenomes and single cells, ensuring improved genomic representation of the microb
This article lists the orders of the Bacteria.The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI) [2] and the phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI). [2] However many taxonomic names are taken from the GTDB release 08-RS214 (28 April 2023).
One feature of the cladogram obtained with this method is the clustering of cell wall morphology (with some exceptions) from monoderms to transitional diderms to traditional diderms. [ 2 ] In the cladogram below, yellow=pseudopeptidoglycan monoderms (Gram variable), red=thick peptidoglycan monoderms (Gram positive), blue=thin peptidoglycan ...
