Q. With reference to the Antimicrobial Resistance (AMR), consider the following statements:
1.It is the resistance of microorganisms to an antimicrobial agent.
2.E. coli has become resistant to the latest generation of antibiotics.
3.Acquired antimicrobial resistance is caused by the structural characteristics of microbes.
How many of the statements given above are correct?
Answer: B
Notes:
Explanation –
Statements 1 and 2 are correct. AMR refers to the ability of microorganisms, like bacteria, viruses, fungi, and parasites, to withstand the effects of antimicrobial agents, such as antibiotics, antifungals, and antiviral drugs. Bacteria like E. coli, Klebsiella, Acinetobacter, Staphylococcus aureus, enterococcus have become resistant to even the latest generation of antibiotics.
Statement 3 is incorrect. Acquired antimicrobial resistance is not caused by structural characteristics of microbes, but rather by genetic changes that occur within the microbe in response to exposure to antimicrobial agents.
