Figure 1. Sequence analysis of the fljAB operon in twoSalmonella 6,7,14 :r:- isolates. MAUVE software was used to compare sequence of the fljAB operon and its neighboring regions in Salmonella 6,7,14 :r:- with the corresponding sequences in S. Virchow BCW_2814 and BCW_2815. The red rectangle represents the phage Entero_P4 inserted in the site close to thefljAB operon, while the blue rectangle depicts a fragment acquired from E. coli .
Figure 2. Phylogenic relationship of the two Salmonella6,7,14 :r:- isolates with 16 reported S. Virchow strains.(A) The phylogenic tree of 2 Salmonella 6,7,14 :r:- isolates and 16 S. Virchow strains based on the cgMLST analysis. The MLST type (ST), CRISPR type, and antimicrobial resistance genes are labelled at the right side with different colors and a black box, respectively. (B) CRISPR typing of 2 Salmonella 6,7,14 :r:- isolates and 16 S. Virchow strains. The spacer names are shown in the upper side of the picture with Vir + NO (VirN) for CRISPR 1 and VirB + NO (VirBN) for CRISPR 2, respectively. The black box represents the strain carrying the spacer. The maximum parsimony tree was constructed using BioNumerics version 7.5 software (Applied Maths, France).
Figure 3. Homology analysis of SGI2 fragment betweenSalmonella 6,7,14 :r:- and S. Emek. The red arrows represent the antimicrobial resistance genes, and the sky-blue arrows represent genes located in SGI2, while the dark blue arrows show the genes at both side of the SGI2. The sequence between 2 TSD sites depicts the integron inserted into the SGI2 site through transposition.
