Abstract

The isolation since 1991 of a new serotype of Salmonella enterica (antigenic formula 4,12:a:-) from harbour porpoises (Phocoena phocoena) at post-mortem examination raised the question of its evolutionary origin. Representative strains of S. enterica serotype 4,12:a:- and strains of eight other serotypes of serogroup O4 with phase-1 flagellar antigen H ‘a’ were examined by EcoRI ribotyping, IS200 fingerprinting and PCR-based profiling. Statistical analysis of results of multiple typing showed that strains of Salmonella serotype 4,12:a:- were genetically distant from those of antigenically similar salmonella serotypes, none of which seemed likely to be the progenitor of the ‘porpoise’ serotype.
