Abstract
In 2009, five monophyletic Escherichia clades were described and referred to as "cryptic" based on the inability to distinguish them from representative E. coli isolates using diagnostic biochemical reactions. Since this original publication, a number of studies have explored the genomic, transcriptomic, and phenotypic diversity of cryptic clade isolates to better understand their phylogenetic, physiological, and ecological distinctiveness with respect to previously named Escherichia species. This chapter reviews the original discovery of the cryptic clades, discusses available evidence that some are environmentally adapted, and evaluates current support for taxonomic designations of these microorganisms. The importance of these clades to clinical research, epidemiology, population genetics, and microbial speciation is also discussed.

期刊介绍：
EcoSal Plus is the authoritative online review journal that publishes an ever-growing body of expert reviews covering virtually all aspects of E. coli, Salmonella, and other members of the family Enterobacteriaceae and their use as model microbes for biological explorations. This journal is intended primarily for the research community as a comprehensive and continuously updated archive of the entire corpus of knowledge about the enteric bacterial cell. Thoughtful reviews focus on physiology, metabolism, genetics, pathogenesis, ecology, genomics, systems biology, and history E. coli and its relatives. These provide the integrated background needed for most microbiology investigations and are essential reading for research scientists. Articles contain links to E. coli K12 genes on the EcoCyc database site and are available as downloadable PDF files. Images and tables are downloadable to PowerPoint files.
