Resistencia a los antibióticos

The video explains how bacteria develop antibiotic resistance by producing proteins that block antibiotic entry into cells. This resistance evolves through natural selection, similar to species evolution. The organism causing SARM infections is particularly adept at this, with resistant strains appearing just four years after penicillin's mass production.

What is the role of natural selection in the development of antibiotic resistance?

What are the implications of discovering resistant strains of bacteria?
