Detailed explanation-1: -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-2: -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-3: -Carbapenem-resistant Enterobacteriaceae (CRE) are a group of bacteria that have become resistant to “all or nearly all” available antibiotics, including carbapenems, which are typically reserved as the “treatment of last resort” against drug-resistant pathogens.
Detailed explanation-4: -Sometimes doctors prescribe a combination of medications. Treatment of a MRSA infection at home often involves a 7-to 10-day course of an antibiotic such as clindamycin, doxycycline, or a combination of sulfamethoxazole–trimethoprim and linezolid.
