How can a short, circular DNA molecule (plasmid) increase the speed at which multiple resistance genes spread through bacterial populations?
Which molecular change in a bacterial gene is most likely to directly alter an antibiotic target and confer resistance?
Which human practice most directly increases selection pressure for antibiotic-resistant bacteria?
On a standard antibiotic disc diffusion test, which result indicates that the bacterium is resistant to the antibiotic on that disc?
Why might incomplete or inappropriate use of antibiotics contribute to resistance?
Which of the following is an antibiotic resistance mechanism that reduces the intracellular concentration of the drug by pumping it out?
Which bacterial mechanism confers resistance by producing an enzyme that breaks down penicillins?
Which process produces new genetic variants in a bacterial population that can lead to antibiotic resistance?
Which term describes the transfer of resistance genes between bacteria by direct cell-to-cell contact using a plasmid?
Which bacterial process can package DNA into a bacteriophage and thereby transfer resistance genes between bacteria?
What is the main role of a plasmid in spreading antibiotic resistance?
