Document Summary
Superinfections: removal of susceptible bacteria leaves the host environment ripe for resistant bacteria (or fungi, be sure to differentiate infection from colonization. It kills the microbiota of the gut (remember antibiotics target whatever they target). Colonization: bacteria just sitting there in your gut, skin, nose, etc. that are not causing infection. Illustrate the relationship(s) between antibiotic resistance and bacteria fitness. Antibiotic resistance is due to both inappropriate use of antibiotics and appropriate use of antibiotics. There is actually no good reason to take all of your antibiotics even when you feel better. Ideally there is an optimal way of taking antibiotics based on symptoms, but patients are not doctors so we tend to just overprescribe the duration to ensure the patient feels better. When someone has septic shock giving the patient an inappropriate antibiotic on average means they will have about a. 10% chance of survival, but when it is appropriate it goes up to about 50%.
