A forest of constantly updated phylogenetic trees with publicly available whole-genome sequencing data from foodborne, bacterial isolates that were deposited in the short sequencing read archives (NCBI SRA/ENA).
If an isolate is within a threshold of 10 SNPs to a "cluster representative", it won't be used in the phylogenetic tree inference, but will be placed, after the tree is made, onto the same clade as its representative, and marked with an asterisk (*).

Visualisation is done with Phylocanvas.
Changes in clusters and links to these subtrees:
Template: The reference sequence to which the reads were aligned to get a consensus sequence. Opens the phylocanvas for a subtree the cluster is on.
Representative: Cluster representative, the non-redundant isolate in the cluster that was used in the phylogenetic tree inference. Opens the phylocanvas for a subtree the cluster is on.
Added: Number of new isolates/total isolates in the cluster.
New: Cluster found in this update.
Mark: Isolates in the cluster are from different source (S), different location (L) and/or were collected by different institutes (I)
Isolates: Jump to the list of isolates in this cluster.
List of all trees in the system:
Template: The reference sequence to which the reads were aligned to get a consensus sequence. (Subtyping information for the templates can be found here). Opens the phylocanvas for the whole tree. NOTE: Some of the trees contain thousand of isolates, and require significant resources on the client-side to load.
Time: The last update.
Download: Download the newick file of the phylogenetic tree with labels (), or without labels () and the metadata in tab separated file (). Or open it in Microreact ().
Search for an isolate by its SRA run id (ie. SRR6457909) or for a cluster the isolate might be in:
