^±ATCC, American Type Culture Collection.

^‡The strain was obtained by S. Maloy via L. Bossi.

^§ All mutant strains are derived from Salmonella enterica serovar Typhimurium strain ATCC14028, with the exception of strain MA8029 which is a derivative of strain LT2.

^†The term “scar” refers to the DNA sequence remaining after excision of antibiotic-resistance cassette (20)
