Since the publication of the Approved Lists of Bacterial Names, the type species of the genus Salmonella has been S. choleraesuis. At the time of publication of the Approved Lists, five Salmonella species had standing in the nomenclature, and the description of S. choleraesuis was the same as that of the serotype of that name. Several studies have shown that the genus Salmonella consists of only one species, and the strict application of the Bacteriological Code would recognize S. choleraesuis (the type species) as the single Salmonella species. This can lead to confusion and hazards since the specific epithet is also the name of a serovar (serovar Choleraesuis). This confusion is increased by the common practice of using serovar names as if they represented species names (e.g., S. typhi, S. choleraesuis, and S. typhimurium). Some serovars (e.g., Salmonella choleraesuis subsp. choleraesuis serovar Typhi) are highly pathogenic and cause a disease different from that caused by other serovars (e.g. S. choleraesuis subsp. choleraesuis serovar Choleraesuis). To avoid further confusion, it is proposed to use for the single Salmonella species a name which has not been used earlier for a serotype. It is thus requested that the type species of the genus Salmonella be Salmonella enterica sp. nov., nom. rev. with strain CIP 60.62 (a H2S-producing clone of strain LT2) as the type strain. Since the name S. choleraesuis is not proposed for rejection, bacteriologists who do not accept the single species concept of the genus Salmonella will be free to use the name S. choleraesuis as a synonym of Salmonella enterica subsp. enterica serotype Choleraesuis.
