[a novel salmonella typhimurium plasmid, panks: an example for plasmid evolution in antibiotic resistance].in this study, a plasmid, carrying ampicillin resistance (ampr) gene, isolated from a clinical isolate of salmonella enterica serotype typhimurium presenting acssut (ampicilin, chloramphenicol, streptomycin, sulphonamide, tetracycline) resistance phenotype, was defined. the length of complete sequence of this plasmid was 8271 base pairs (bp), and it was named as panks owing to its isolation place (plasmid-ankara- salmonella). the plasmid was analyzed for potential reading frames and structural f ...200818822880
