Describe a mechanism that can lead to the development of antibiotic-resistant bacterial strains?

Expert Solution

Question

The bacteria could become resistant to the antibiotics by one of the following mechanism :

I. Enzymatic degradation of the antibacterial drugs. The bacteria have several enzymes that have the ability to degrade the structure of antibiotics so that it become ineffective.

II. The bacteria have the ability to mutate it's structure that lead to the change in the structure of bacterial proteins that are the antibacterial targets.

III. The bacteria also mutate it's plasma membrane structure so that its permeability to the antibiotics will get changed and antibiotic is not able to enter in the cell.

IV. In some cases, the bacteria increases the activity of efflux proteins that expel the antibiotics that try to enter in the cell.

Describe TWO specific cellular mechanisms through which a bacterium can become resistant to an antibiotic. – Please note that this question is NOT about practices or actions we do that contribute to antibiotic resistance in bacteria, such as not taking the entire prescribed dose. Please remember that bacterial cells become resistant or tolerant to antibiotics, NOT human cells, or the human body. – *** Perform some research in the college's online library, a microbiology textbook, and other credible scientific sources...

ErmTR is an enzyme found in S. pyogenes strains that are resistant to erythromycin. While working in the lab one afternoon you discover a small molecule (C23) that inhibits the activity of ermTR. To assess the type of inhibitor you discovered, you set up reactions with 6 different concentrations of erythromycin and varying amounts of the C23 small molecule you discovered. To each reaction you add 2 x 10-12 mol of ermTR (total reaction volume: 15 mL) and measure the...
