"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."
What is a persistent strain?
CDC uses “persistent” to describe some strains of bacteria that have caused illness for years. The strains continue to cause illness, even though the number of illnesses they cause might vary over time. The strains are sometimes linked to more than one source, making them harder to control.
