UPSC 2019: Which of the following are the reasons for the occurrence of multi-drug resistance in microbial pathogens in India? 1. Genetic predisposition of some people 2. Taking incorrect doses of antibiotics to cure diseases 3. Using antibiotics in livestock farming 4. Multiple chronic diseases in some people Select the correct answer using the code given below.

(b)2 and 3 only
(c)1, 3 and 4
(d)2, 3 and 4
Attempt This Question
Not attemptedCorrect Answer: (b) 2 and 3 only
Multi-drug resistance evolves in microbes when antibiotics are misused: (2) sub-optimal or incomplete dosing in humans and (3) routine prophylactic use in livestock both impose selection pressure favouring resistant strains. Human genetic predisposition (1) and the mere presence of multiple chronic diseases (4) affect host susceptibility, not microbial evolution; they are therefore not causes of resistance. Hence only 2 and 3 are correct ⇒ option (b). ([edukemy.com](https://edukemy.com/blog/upsc-prelims-2019-question-98/?utm_source=openai))
