Feedback:
Selective pressure, or natural selection, refers to the survival of the fittest bacteria. When antibiotic therapy is initially begun, the weakest bacteria are killed first while the strongest bacteria, which are best able to withstand the effects of antibiotic therapy, remain. This contributes to antibiotic resistance. Resistance is not the result of an extended G0 phase, impaired distribution, or bacterial appropriation of human genetic material.
