Natural isolates of Salmonella enterica serovar Dublin carry a single nadA missense mutation.
Nicotinic acid is required by most isolates of Salmonella enterica (serovar Dublin), a pathogen of cattle. A single nadA missense mutation causes the nutritional requirement of all serovar Dublin isolates tested. Models for persistence of this allele are tested and discussed.
