Abstract excerpt
Listeria monocytogenes epidemic clone II (ECII) strains are unusual in being completely resistant to phage when grown at low temperatures (≤30°C). In the current study we constructed and characterized a mariner-based mutant (J46C) of the ECII strain H7550-Cd(S) that lacked temperature-dependent resistance to phage. The transposon was localized in LMOh7858_2753 (open reading frame [ORF] 2753), a member of a 12-ORF...
