A history of EcoSal Plus

EcoSal Plus (ESP) is the authoritative online review journal that publishes an ever-growing body of expert reviews covering virtually all aspects of Escherichia coli, Salmonella, and other members of the order Enterobacterales and their use as model microbes for biological explorations. This review will cover the history of ESP, starting with its origins as multi-volume printed books entitled Escherichia coli and Salmonella: Cellular and Molecular Biology that became "the Bible" for information on the physiology, metabolism, genetics, and other aspects of E. coli and Salmonella. After two printed editions, this resource moved online as EcoSal in an era when electronic publishing was still in its infancy. Progress in establishing EcoSal was slow due to technical issues of online publishing and difficulties in recruiting authors to produce new material. This venture was relaunched in 2013 as EcoSal Plus in a completely new web platform that was much more user (and author) friendly and with an expanded scope to include other members of the order Enterobacterales. EcoSal Plus will be ending as a standalone publication but will merge with Microbiology and Molecular Biology Reviews to continue providing high-quality, authoritative reviews on E. coli, Salmonella, and related organisms.
