Intrinsic Resistance: This is a natural resistance some bacteria have to certain antibiotics due to inherent structural or functional characteristics. Acquired Resistance: This develops through genetic changes, either by mutation or acquiring resistance genes from other bacteria. Cross-Resistance: This occurs when resistance to one antimicrobial agent confers resistance to another, often due to similar mechanisms of action. Multiple Resistance: This is when a microorganism is resistant to multiple antimicrobial agents used to treat it.
