Tracing Back the Evolutionary Route of Enteroinvasive (EIEC) and Through the Example of the Highly Pathogenic O96:H19 EIEC Clone.

Enteroinvasive (EIEC) cause intestinal illness through the same pathogenic mechanism used by spp. The latter species can be typed through genomic and phenotypic methods used for and have been proposed for reclassification within species. Recently the first appearance of a highly pathogenic EIEC O96:H19 was described in Europe as the causative agent of two large outbreaks that occurred in Italy and in the United Kingdom.
