Anti-biotic resistance

Antibiotic resistance refers to the capacity of bacteria to survive or grow despite exposure to concentrations of antibiotics that would normally inhibit or kill them

What is anti-biotic?

Antibiotics are substances produced by microorganisms or their derivatives that, in low concentrations, inhibit the growth of or destroy other microorganisms

Classification of antibiotics

Uses of antibiotics

  • Treatment of bacterial infections
  • Prophylaxis in surgery
  • Management of life-threatening infections

Mechanism of action:

ANTIBIOTICS

Act on Bacterial Cell

  1. Inhibit Cell Wall Synthesis
  2. Inhibit Protein Synthesis
  3. Inhibit Nucleic Acid Synthesis
  4. Inhibit Metabolic Pathway
  5. Damage Cell Membrane

    Bacterial death / Growth inhibition

So what happens when antibiotics resistance occurs

ANTIBIOTIC RESISTANCE

Bacterial Adaptation

  1. Enzymatic Inactivation of Drug
  2. Alteration of Target Site
  3. Reduced Drug Entry
  4. Efflux Pump Activation
  5. Bypass of Metabolic Pathway

    Antibiotic becomes ineffective

Causes of antibiotics resistance

  • Overuse of antibiotics
  • Incomplete treatment course
  • Wrong dose / wrong drug
  • Self-medication
  • Use in viral infections

Prevention of anti biotic resistance

**

  • Use antibiotics only on prescription
  • Complete full course
  • Correct dose & duration
  • Avoid self-medication
  • Maintain hygiene & infection control

Antibiotic resistance is a serious health issue caused by improper use of antibiotics. Responsible use and awareness are essential to prevent it.
