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.

How do bacteria typically achieve resistance to antibiotics?

• By producing a protein that blocks antibiotic entry

• By moving faster

• By increasing their size

• By changing their color

What is the primary method by which bacteria prevent antibiotics from entering the cell?

• By producing a specific protein

• By altering their DNA

• By producing a protective capsule

• By hiding from the antibiotic

What process is responsible for the development of antibiotic resistance?

• Genetic engineering

• Natural selection

• Artificial selection

• Random mutation

Which organism is known for developing resistance to antibiotics effectively?

• E. coli

• SARM

• Mycobacterium tuberculosis

• Staphylococcus aureus

How soon after the mass production of penicillin were resistant strains discovered?

• 10 years

• 1 year

• 20 years

• 4 years
