What is antibiotic resistance and how does it arrive in bacteria?

Answered

Antibiotic resistance occurs when bacteria evolve mechanisms to survive exposure to antibiotics that would normally kill them or inhibit their growth. This can arise through genetic mutations or by acquiring resistance genes from other bacteria via processes like conjugation, transformation, or transduction. These resistance genes may encode proteins that neutralize the antibiotic, alter the target site of the drug, or expel the drug from the cell. Antibiotic resistance is often facilitated by the horizontal gene transfer of resistance plasmids, allowing resistant bacteria to proliferate rapidly, especially in environments with frequent antibiotic use.
