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

Enteroinvasive Escherichia coli (EIEC) cause intestinal illness through the same pathogenic mechanism used by Shigella spp. The latter species can be typed through genomic and phenotypic methods used for E. coli and have been proposed for reclassification within E. coli 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.

Phylogenomic analysis of Calyptratae: resolving the phylogenetic relationships within a major radiation of Diptera

The Calyptratae, one of the most species‐rich fly clades, only originated and diversified after the Cretaceous–Palaeogene extinction event and yet exhibit high species diversity and a diverse array of life history strategies including predation, phytophagy, saprophagy, haematophagy and parasitism. We present the first phylogenomic analysis of calyptrate relationships. The analysis is based on 40 species representing all calyptrate families and on nucleotide and amino acid data for 1456 single‐copy protein‐coding genes obtained from shotgun sequencing of transcriptomes.
