Ways bacteria resist antibiotics
|
1.degrade/alter antibiotic (beta-lactamase)
2.Efflux Pump- pumps it out of the cell (tetracycline) 3. Uptake Reduction 4. Overproduction of target 5. Alteration of Target (penicillin binding proteins change, 50s |

what do you need for horizontal gene transfer to occur?
|
recombination as a double crossover
|
|
|
Transformation
|
Donor releases free DNA by lysis. DNA attaches to a recipient cell. Gene recombines with the recipient's chromosome
|
|
|
Conjugation
|
use of the large pili.
When the plasmid transferred to another cell, it drags along the chromosome with it, integration with double cross over |
|
|
What are transposons
|
Jumping genes. Carry insertion sequence and other genes. Allow for antibiotic resistance/ resistance Plasmid
|
|
|
Transduction
|
Utilization of Viruses
Generalized transduction- transfers any bacterial gene Specialized transduction- transfers only genes adjacent to the site of integration |
