Arguments against the replacement of type species of the genus Salmonella from Salmonella choleraesuis to 'Salmonella enterica' and the creation of the term 'neotype species', and for conservation of Salmonella choleraesuis.

The proposals of Le Minor and Popoff in 1987 and again of Euzéby in 1999 on the type species of the genus Salmonella are in violation of Rule 20a of the Bacteriological Code (1990 Revision) and should be rejected. The introduction of the term 'neotype species' should be rejected. The specific epithet choleraesuis in the binary combination Salmonella choleraesuis should be conserved. The serovar name Choleraesuis should be changed to Hogcholera.
