Mechanisms of resistance to antibiotics

What are antibiotics?

How does this resistance occur?

• Antibiotic resistance happens when resistant bacteria multiply.
• While resistant bacteria multiply, vulnerable bacteria die off.
• Over time, the resistant bacteria are the only bacteria left in the body.
• Immune to antibiotics, the bacteria continue to weaken the body's health.

Why does this resistance Occur?

• This resistance occurs due to:
•          -Selective pressure
•          -Mutation
•          -Gene transfer
•          -Societal pressures

Why does this resistance occur? (Continued)

•          -Inadequate diagnostics 
•          -Hospital use
•          -Agricultural use
•          -Innappropriate drug use

Vista

• Variation- Resistant bacteria, vulnerable bacteria
• Inheritance- Resistance to antibiotics
• Selection- Vulnerable bacteria die off while the resistants multiply
• Time- Happens after multiple generations of bacteria
• Adaption- Bacteria grow resistant to antibiotic, making antibiotics useless
