The use of antibiotics caused the mutation that produced MRSA. True or False?

Question

Quizplus · Accepted Answer

The use of antibiotics did not directly cause the mutation that produced MRSA, but it did create a selection pressure that favored the survival and spread of MRSA strains. This is because antibiotics killed off susceptible bacteria, allowing resistant bacteria like MRSA to thrive and reproduce. The mutation that led to MRSA's antibiotic resistance likely occurred naturally through genetic changes over time.
