Extensive variation in the O-antigen gene cluster within one Salmonella enterica serogroup reveals an unexpected complex history.

Journal of bacteriology - 1 Mar 2002

Abstract excerpt

The 46 serogroups of Salmonella enterica have different O-antigens, and each is thought to have a specific form of the O-antigen cluster. Comparison of the 145 serovars of serogroup B revealed much more intraserogroup genetic diversity than expected. The O27 factor, due to an alpha 1-6 linkage between O units in place of the more common alpha 1-2 linkage and previously thought to be due to a converting...
