On-the fly comparisons by querying public databases.
Ref: Samuel G., Hogbin.JP, Wang L and Reeves PR.(2004) Relationships of the Escherichia coli O157, O111, and O55 O-antigen gene clusters with those of Salmonella enterica and Citrobacter freundii, which express identical O antigens.J Bacteriol. 2004 Oct;186(19):6536-43.
Escherichia coli O157, Salmonella enterica O30
and Citrobacter freundii F90 have identical O-antigen structures.
Similarly, the E.coli O55 structure is identical to that of
S.enterica O50. For both the S.enterica O30, C. freundii
F90, E. coli O157 group and the S.enterica O50, E.coli
O55 group of O-antigens the gene clusters have identical or nearly identical organisations.
Here we demonstrate the stepwise fashion that
can be used through WebACT to query public databases
using accession numbers for the 5 O-antigen gene
clusters and to display the similarities easily
