Which mechanism of drug resistance involves the microbe producing enzymes that are able to destroy the antimicrobial?

A. Drug inactivation
B. Efflux pumps
C. Enzymatic bypass
D. Target mimicry


Sagot :

Final answer:

Efflux pumps in drug resistance are effective against diverse antimicrobials, being nonspecific to a particular class, with target overproduction and enzymatic bypass as other common mechanisms.


Explanation:

Efflux pumps are a mechanism of drug resistance where microbes produce pumps that actively remove antimicrobials from the cell, reducing their effectiveness. This mechanism is effective against a wide range of antimicrobials in multiple classes.

Efflux pumps are nonspecific to a particular class of antimicrobials, making them broadly effective against different types of drugs. This strategy allows microbes to expel antibiotics before they can exert their effect.

Drug resistance through target overproduction or enzymatic bypass involves producing enzymes that either increase the target so the drug has more to bind to or finding alternative pathways to bypass the drug's inhibitory effects.
