Bacteria evolve rapidly, developing resistance to antibiotics through genetic mutations and natural selection. When exposed to antibiotics, some bacteria survive by altering their cell structures, producing enzymes that neutralize drugs, or pumping out harmful substances. Overuse and misuse of antibiotics accelerate resistance, making infections harder to treat. Superbugs, such as MRSA, pose serious health threats as they withstand multiple antibiotic treatments. Researchers develop new drugs...
