Plasmid curing of antibiotic resistant Escherichia coli isolates from urine and stool samples

The origin of bacteria resistance to antibiotics can either be chromosomal or extra-chromosomal (plasmid mediated) and one way of determining the origin of bacterial drug resistance is by plasmid elimination. In this study, the antibiotic susceptibility of seven Escherichia coli isolates (numbered 1-7) from urine and stool samples, were assessed using the disk diffusion method. The 10 antibiotics used were:...
