a
Plants A, B, and C correspond to plants M2, M4, and M1, respectively, described by Møretrø et al. (22).
b
Listed MLVA profiles correspond to variable number tandem repeat (VNTR) loci LMV6-LMV1-LMV2-LMV7-LMV9 described by Lindstedt et al. (66). Persistent or sporadic MLVA profiles are determined using the criteria described in Materials and Methods.
c
L. monocytogenes strains were isolated by Møretrø et al. (22).
