Multiple Choice
Which of the following statements about the mechanism of antibiotic resistance in bacteria is false?
A
Antibiotic resistance is a result of bacteria producing more antibiotics.
B
Bacteria can develop resistance by altering the target site of the antibiotic.
C
Antibiotic resistance can be acquired through horizontal gene transfer.
D
Antibiotic resistance is primarily caused by the overuse of antibiotics in agriculture.
Verified step by step guidance
1
Understand the concept of antibiotic resistance: Antibiotic resistance occurs when bacteria evolve mechanisms to withstand the effects of antibiotics, making them less effective.
Identify the mechanisms of resistance: Bacteria can develop resistance through various mechanisms such as altering the target site of the antibiotic, enzymatic degradation of the antibiotic, or efflux pumps that remove the antibiotic from the cell.
Explore horizontal gene transfer: This is a process where bacteria acquire resistance genes from other bacteria, often through plasmids, transposons, or bacteriophages, allowing them to rapidly gain resistance traits.
Consider the impact of antibiotic use: Overuse and misuse of antibiotics, especially in agriculture, can lead to increased selection pressure, promoting the survival and proliferation of resistant strains.
Evaluate the false statement: The statement 'Antibiotic resistance is a result of bacteria producing more antibiotics' is incorrect because resistance is not due to bacteria producing antibiotics, but rather their ability to survive despite the presence of antibiotics.
