Notizen:
We report the cloning and mapping of the entire rfb gene cluster of a group C2 Salmonella strain. Comparison with the rfb region of group B strain LT2 and group D strain Ty2 reveals an 11.8kb central region of limited similarity flanked by regions of high similarity. The genes from the central region confer a group C2 O-antigen structure on a Salmonella LT2 partial delete strain. The significance of this region in relation to function and evolutionary origin is discussed. We also report evidence for the existence of an O-antigen chain-length determinant in Escherichia coli K12 and propose a model for a possible mechanism by which a preferred chain length is determined.
