Genomic portrait of the evolution and epidemic spread of a recently emerged multidrug-resistant Shigella flexneri clone in China.

Abstract excerpt

Shigella flexneri is the major cause of shigellosis in developing countries. A new S. flexneri serotype, Xv, appeared in 2000 and replaced serotype 2a as the most prevalent serotype in China. Serotype Xv is a variant of serotype X, with phosphoethanolamine modification of its O antigen mediated by a plasmid that contained the opt gene. Serotype Xv isolates belong to sequence type 91 (ST91). In this study,...
