Lesson 1B- Antibiotic Treatment
Why are certain classes of antibiotics prescribed to treat specific bacterial infections? -
ANS-- antibiotics are prescribed specifically for the pathogen they treat
- different mechanisms of action based on structure
How do bacterial cells transfer genes from one to another? Why Is this important? -
ANS-- can evolve and pass on resistance genes, making infection harder to treat (ex.
conjugation, transformation, transduction)
What actions are humans taking that are contributing to bacterial becoming resistant to
commonly used antibiotics? - ANS-- not taking them as prescribed
- prescribing when unnecessary
- taking expired antibiotics
- not taking for prescribed duration
Pili - ANS-stick to surfaces; conjugation
Capsule - ANS-protection
Cell membrane - ANS-transport
Cell wall - ANS-structure and protection
Plasmid - ANS-stores bonus DNA
Falgella - ANS-locomotion
Ribosomes - ANS-synthesize proteins
Nucleiod - ANS-stores DNA
Cytoplasm - ANS-fluid that fills the cell
Gram + - ANS-- stain purple
- thick peptiglycan
Gram - - ANS-- stain pink
- thin peptiglycan
