Boxes colored orange indicate the genes originally used to screen for the EAEC.
Boxes colored green indicate the presence of the gene.
Strain name boxes colored in purple indicate that the isolate was the sole pathogen identified in the sample.
woWhole operon present.
#
MLST − multi-locus sequence type.
*
The aaiC gene in this isolate is the same variant as found in C700-09 (Jonsson et al.).
Boxes colored blue indicate a gene with 47% homology to aap from 042.
Boxes colored yellow indicate that a gene with low homology, 35%, was identified in the contigs for these strains.
