Fig 1.
Maximum-likelihood phylogeny based on full length sequence SNPs analysis for 71 pSLT plasmids from Australian and international isolates of S. Typhimurium (A) compared with that for the host chromosomes based on core SNPs analysis (B). The scale bar shows the proportion of total substitutions for the site. The legend indicates the lineages (Repeats Groups) for the clusters according to Fu et al, 2017 [12].
Table 1.
Number of isolates of S. Typhimurium with pSLT plasmids with indicated number of traD 9 bp repeats for nominated genotypes of Clade II.
Fig 2.
Theoretical structure of 103513 bp pSLT plasmid of 10ST02333 shown as modifications to the gene map sequence of LT2 pSLT AE006471.
The antibiotic resistance cassette is shown as an insert in gene PSLT045 and another IS26 is shown inserted into the traD gene. Figure drawn using GenomeVx http://wolfe.ucd.ie/GenomeVx/ [17].
Fig 3.
Theoretical structure of 71167 bp pSLT plasmid of 09ST03520 shown as modifications to the gene map sequence of LT2 pSLT AE006471.
The antibiotic resistance cassette is shown as an insert in gene PSLT044 and another IS26 is shown inserted before gene PSLT064. The deleted sequence between PSLT064 and the point within traD gene is shown. The STTR10pl VNTR located intergenic between PSLT064 and PSLT065 (ssbB) is consequently deleted as well.
