a
A plus sign denotes the presence, and a minus sign denotes the absence, of the indicated LPS structure.
b
There is no apparent band A component visible on gels of this species because it appears to be substituted with O antigen (4).
c
This species does make a sugar group, but it may only be a disaccharide or a mixture of di-and trisaccharides, possibly because of an inefficient wlb H-encoded transferase (25).
