Genomic Diversity in Salmonella enterica

Part of the Food Microbiology and Food Safety book series (FMFS)


Salmonella enterica is a bacterial species which contains diversity within the limits of a single species ancestry. Selection by different habitats, represented by the extraordinary number of host species colonised by S. enterica, and the need to successfully transmit through water, soil, or fomites (from host to host) has driven this diversity. An understanding of the impact of this diversity needs to drive the naming of isolates which should be clinically and biologically relevant in terms of niche occupation as well as in terms of ancestry; all we need is an accurate sequence of the entire genome and a comprehensive understanding of the biology of the variation seen. Currently serotype is the working unit of classification but the variation seen within each serotype is itself very variable and so not all serotypes are equal. Here we describe the current genomic data from several common serotypes and discuss the biology behind the different levels of variation.
