Question 24
Which of the following are the reasons for the occurrence of multi-drug resistance in microbial pathogens in India?
- Genetic predisposition of some people
- Taking incorrect doses of antibiotics to cure diseases
- Using antibiotics in livestock farming
- Multiple chronic diseases in some people
Select the correct answer using the code given below.
View correct answer and explanation
Correct answer: B
Correct Option: B
Explanation:
Antimicrobial resistance is selected by improper antibiotic use and extensive antibiotic exposure in livestock; patient genetic predisposition and multimorbidity do not themselves produce drug-resistant microbial strains.
Statement / Pair Analysis:
1 (Incorrect): Human inherited susceptibility is not a direct cause of microbial multidrug resistance.
2 (Correct): Wrong doses or incomplete antibiotic treatment favour survival of resistant organisms.
3 (Correct): Antibiotic use in livestock can select resistant microbes that spread to humans.
4 (Incorrect): Having several chronic conditions does not inherently cause microbial resistance, although exposure to antibiotics may increase.
Option-wise Analysis:
A (Incorrect): It includes false item 1 (Human inherited susceptibility is not a direct cause of microbial multidrug resistance); omits true item 3 (Antibiotic use in livestock can select resistant microbes that spread to humans).
B (Correct): Includes all and only the true statements/pairs.
C (Incorrect): It includes false item 1 (Human inherited susceptibility is not a direct cause of microbial multidrug resistance); includes false item 4 (Having several chronic conditions does not inherently cause microbial resistance, although exposure…); omits true item 2 (Wrong doses or incomplete antibiotic treatment favour survival of resistant organisms).
D (Incorrect): It includes false item 4 (Having several chronic conditions does not inherently cause microbial resistance, although exposure…).
