"This strain of Salmonella Infantis is relatively diverse genetically. Bacteria in the strain are within 82 allele differences of one another by core genome multilocus sequence typing (cgMLST). This is more genetically diverse than typical multistate foodborne outbreaks, in which bacteria generally fall within 10 allele differences of one another."
