Phenotypic and Genotypic Characterization of Clinical Enterotoxigenic <i>Escherichia coli</i> Isolates from Shenzhen, China

Abstract

ETEC isolates in Shenzhen of China appeared highly diverse, yet some isolates belonged to well-defined clonal groups sharing a unique set of virulence factors, serotypes, and MLST sequence types. Facing the challenge of ETEC antigenic diversity and geographic variation, novel molecules and/or classical antigens designed by novel strategies might contribute to ETEC vaccine development.
