Detailed explanation-1: -Antimicrobial resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Resistant infections can be difficult, and sometimes impossible, to treat.
Detailed explanation-2: -Antimicrobial resistance: The ability of a microbe (germ) to resist the effects of a drug. Antimicrobial-resistant germs are not killed by the drugs that are typically used against them and may continue to multiply. Antimicrobial resistance includes antibacterial, antifungal, and antiviral resistance.
Detailed explanation-3: -The spread of antibiotic resistance in pathogenic bacteria is a simple and elegant example of evolutionary adaptation by natural selection. Bacteria can become resistant to antibiotics through mutations that alter the cellular targets of antibiotics or by acquiring dedicated resistance genes from other bacteria.
Detailed explanation-4: -8. What is meant by antibiotic resistance? (a) It means our body has become resistant to the antibiotic.
Detailed explanation-5: -Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. For example, some bacteria have developed biochemical “pumps” that can remove an antibiotic before it reaches its target, while others have evolved to produce enzymes to inactivate the antibiotic.
