LOCUST

Intro: 

A custom sequence locus typer for classifying microbial genotypic and phenotypic attributes.

You are here

LOCUST (LOcus CUstom Sequence Typer) is a custom sequence locus typer tool for classifying microbial genomes. It provides a fully automated opportunity to customize the classification of genome-wide nucleotide variant data most relevant to biological research.

Key Features

  • Ability to type bacterial genomes using any user-supplied DNA sequence.
  • Automated processing from genome sequence download to genotypic classification and phylogenetic inferences.
  • User customization enabling the processing of existing or generation of novel, classification schemes.
  • Genomic assertions based on genotypic classifications.

Sample Output

Sample output from LOCUST

To investigate the relationship of Enterobacter aerogenes genomes in the context of other members of the family Enterobacteriaceae, LOCUST was used to construct a phylogenetic universal marker tree of representative genomes of members of the family Enterobacteriaceae. These results supported the previously proposed argument to rename E. aerogenes to Klebsiella aerogenes.
