How anti-biotic resistance occurs for a bacterial strain - Coggle Diagram
How anti-biotic resistance occurs for a bacterial strain
Escherichia coli
Variation
Adaptation
Survival
Reproduction
Population growth over time
new antibiotics are created
population decrease
new variation occurs
VASRP process starts again
The new strain is spread to others
Scientist create new antibiotics to kill of bacteria
new strain survives against antibiotics
E.coli adapts to new medication by changing again and becoming resistant
sense changes
temperature
37'C
Adapts to extreme temperatures
pH
certain chemicals
osmolarity
change in E.Coli Ribosomes doesn't allow drugs to bind to particles
The strain of E.Coli changes and a variation occurs
shiga toxin
enzyme that destroys the medication
resistance to multiple drugs
Evolutionary selection called negative frequency dependency selection (NFDS)
variation in the genes that are involved in allowing the bacteria to colonize in the human gut
Staphylococcus aureus
Variation
Adaptation
Survival
Reproduction
Population changes
Methicillin-resistant Staphylococcus aureus (MRSA)
individual bacteria develop a unique resistance gene
