EnteroBASE EnteroBase 1 is a Powerful, User-Friendly Online Resource for Analyzing and Visualizing Genomic Variation within Enteric Bacteria

EnteroBase aims to establish a world-class, one-stop, user-friendly, backwards-compatible but forward-looking genome database, Enterobase – together with a set of web-based tools, EnteroBase Backend Pipeline – to enable bacteriologists to identify, analyse, quantify and visualize genomic variation principally within the genera:

  • Escherichia
  • Salmonella
  • Yersinia
  • Clostridiodes (Clostridium difficile)
  • Moraxella

EnteroBase is populated with over 200,000 of genomic assemblies derived from publicly available complete genomes, sequence read archives and user uploads. Enterobase implements core genome MLST schemes to catalogue these genomic assemblies into biological population, and visualize the genetic relationships using GrapeTree 2,3, which supports facile manipulations of both tree layout and metadata. It calculates phylogenies using the neighbor-joining (NJ) algorithm, the classical minimal spanning tree algorithm (MSTree), or an improved minimal spanning tree algorithm which we call MSTree V2.

 

GrapeTree is named after the clusters of related bacterial strains that tends to be presented in minimal spanning trees. Our GrapeTree GUI is available within EnteroBase once you have created a workspace or connected to somebody else’s workspace.
