Flashcards

Antimicrobial Resistance (AMR)

The ability of microorganisms to resist the effects of antimicrobial drugs, making infections more difficult to treat.

Opportunistic Pathogen

A type of pathogen that can cause disease only when the host's immune system is weakened.

Commensal Bacteria

Bacteria that live on or in the human body without causing harm.

Primary Consequence of AMR

The primary consequence of AMR is the inability to treat infections effectively, leading to higher mortality rates.

Enzymatic Degradation

A mechanism of AMR where bacteria produce enzymes that break down antimicrobial drugs, rendering them ineffective.
