FIGURE 4

The genomic context of the resistance genes in the antibiotic resistance islands. Most of the clustered resistance genes were found in the same genetic context in strains of different origins and were flanked by mobile genetic elements and plasmid-related genes. The figure illustrates only the context and is not scaled to the actual length of the genes and intergenic sequences. (A–D) a lsa(E), lnu(B) and aminoglycoside resistance genes harboring genomic islands found in husbandry and human related strains, (E,F,L) a tetracycline resistance gene cluster variants found in human and husbandry related strains, (G) a erm(B) and aminoglycoside resistance genes harboring genomic in human related strains, (H) a cat_5 and str_1 genes harboring genomic island in human and husbandry related strains, (I) a tetracycline resistance cluster and cat_5 gene harboring genomic island found in husbandry related strains, (J) a erm(B) and dfr(G) genes harboring genomic island found in poultry related strains, (K) an aminoglycoside resistance genes harboring genomic island found in human related strains, (M) cat(pc221)_1 and erm(B) genes harbouring genomic island found in human related strains.
