Maximum likelihood tree of 1,557 K. pneumoniae strains.

A phylogenetic tree was built using a 2,253,033 bp long core alignment. Contextual information relevant to the collection was visualized using Phandango and includes ST (of which the major ones are indicated on the tree); GD or TD insertion in the loop L3 of ompK36, in black and red, respectively; presence or absence of ompK36, in orange and purple, respectively; presence or absence of ompK35, in orange and purple, respectively. Additional metadata include year(date) of isolation, in a gradient from purple to yellow; source and geographical region of isolation in a rainbow gradient; and presence of major beta-lactamases (bla) alleles identified, in dark blue.
