Effects Of Long-Term Exposure To Kanamycin And/Or Ampicillin On Resistance Genes On An E. Coli Plasmid, Justin W.R. Kerby Ii
Master's Theses
Multi-drug-resistant bacteria are a major cause of hospital-acquired infections and antibiotic resistance in these organisms is often plasmid mediated, which has become a growing concern. Plasmids conferring resistance to multiple antibiotics are increasingly becoming a common source of antibiotic resistance. The behavior of these plasmids under and in the absence of selective pressure is not yet fully understood. Therefore, to determine the behavior of a multiple-resistance plasmid under selective pressure pCR 2.1-TOPO, a commercial plasmid, was inserted into an Escherichia coli host and grown in a continuous culture under four conditions: broth with 1) kanamycin alone, 2) ampicillin alone, 3) …
