BGI assembly of German E. coli outbreak strain

BGI has released a ‘complete’ assembly of TY2482. Here is what it looks like, with the 4 other available outbreak genomes mapped against it (4 inner rings) plus available references.

BGI assembly (TY2482, reference) vs 4 other outbreak genome assemblies (from inner: purple=GOS1, pink=GOS2, green=HPA strain, blue=LB226692). Yellow = reference sequence... for chromosome, Ec55989 and red=VT2 phage; for IncI plasmid, pEC_Bactec; for mini plasmid, pO26-S1; for EAEC plasmid, red/yellow/aqua = 55989p, pO86A1, pAA, orange=agg operon.

 

Chromosome:

BGI assembly (TY2482, reference) vs 4 other outbreak genome assemblies (from inner: purple=GOS1, pink=GOS2, green=HPA strain, blue=LB226692). Yellow = Ec55989, red=VT2 phage.

 

EAEC plasmid, novel version and carrying agg operon (aggregative adhesion fimbriae class I; AAF/I):

BGI assembly (TY2482, reference) vs 4 other outbreak genome assemblies (from inner: purple=GOS1, pink=GOS2, green=HPA strain, blue=LB226692). Red = 55989p, yellow = pO86A1, aqua = pAA, orange=agg operon.

 

IncI plasmid, carrying extended spectrum beta-lactamase blaCTX-M-15:

Mini plasmid, replication regions only:

Mini plasmid ("selfish plasmid", carrying only rep genes). Yellow = pO26-S1.
