Escherichia coli O-antigen Database
Theodor Escherich, 1857-1911)
is a gram-negative, rod-shaped bacterium.
Like all gram-negative bacteria it has an inner and outer membrane. The latter is covered by
lipopolysaccharides, LPS, which consist of an O-antigen, a core structure and a lipid A moiety.
This database contains structures of the repeating units that comprise the O-antigen.
Using the database
Items in the database can be accessed in three ways from the menu above.
Either the desired item can be selected from a complete listing of the database using
or the database can be searched by
any data contained in the records using Search
. In addition to this it is
possible to browse the database using the Summary Table
This table also shows glycosyltransferase status of each serogroup and gives a statistical summary
of the database.
