- Prevent Infection
- Antiseptics
- Apply: skin or wounds
- Kill bacteria in localised area
- Reduce likelihood: wound infected or bacteria entering blood
- Disinfectants
- Kill bacteria in localised area
- Reduce likelihood: bacteria transferred from environment to patient/wound
- Apply: inanimate objects & surface
- Antibiotics
- Reduce likelihood: Passing on infection by direct or indirect contact
- Slow bacterial cell growth & reproduction
- Fewer cells produced
- More time for immune system to respond
- Clonal expansion of B cells
- Antibody production
- Clonal expansion of B cells
- Phagocytosis
- More time for immune system to respond
- Fewer cells produced
- Slow bacterial cell growth & reproduction
- = antibacterial drugs (kill / prevent bacteria reproduction)
- Broad spectrum: destroy wide range bacteria & pathogen, (including good/neutral flora)
- Bactericidal: destroys pathogens present
- Bacteriostatic: Inhibits the growth of the microorganism
- Selective Toxicity: interfere with metabolism & function of pathogen with minimum damage to human host
- Inhibit bacterial cell wall synthesis
- Cell lysis
- Disrupt cell membrane - changing it's permeability
- Cell lysis
- Inhibit nucleic acid synthesis, replication & transcription
- Inhibit protein synthesis
- Inhibit bacterial cell wall synthesis
- Reduce likelihood: Passing on infection by direct or indirect contact
- Antiseptics
