Detailed explanation-1: -Antimicrobial Resistance (AMR) occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to medicines making infections harder to treat and increasing the risk of disease spread, severe illness and death.

Detailed explanation-2: -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.

Detailed explanation-3: -Print. About Antimicrobial Resistance. 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-4: -Penicillins-for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin. Cephalosporins-for example, cefaclor, cefadroxil and cefalexin. Tetracyclines-for example, tetracycline, doxycycline and lymecycline. Aminoglycosides-for example, gentamicin and tobramycin.

Detailed explanation-5: -Definition. An antimicrobial therapy kills or inhibits the growth of microorganisms such as bacteria, fungi, or protozoans. Therapies that kill microorganisms are called microbiocidal therapies and therapies that only inhibit the growth of microorganisms are called microbiostatic therapies.
