Figure 2From: Correlation between the genomic o454-nlpD region polymorphisms, virulence gene equipment and phylogenetic group of extraintestinal Escherichia coli (ExPEC) enables pathotyping irrespective of host, disease and source of isolationMinimum spanning tree depicting the distribution of o454-nlpD patterns I to IV of extraintestinal (n?=?367) and commensal (n?=?143) E. coli strains in their phylogenetic background, as determined by MLST. Sequence types (STs) are indicated by numbers.Back to article page
