title: Evolution of Salmonella O antigen variation by interspecific gene transfer on a large scale.
abstract: The O antigen is a bacterial surface polysaccharide made up of repeats of a short oligosaccharide. There are about 60 forms of O antigen in Salmonella, and genetic analysis indicates that these were acquired by interspecific gene transfer.
