Document Summary
Learning objectives: explain how phage therapy could be used to control antibiotic resistant bacteria, evaluate whether a situation is appropriate phage therapy or antibiotic therapy. Answer: it would be options 1 and 4. Bacteriophage can be very specific to certain types of bacteria. Test bacteria spread on top of an agar plate. Discs containing different antibiotics placed on plate. Measure zone of inhibition: zone of inhibition is the clear area around the disc which tells you that no bacteria can grow in that area. Smaller zones indicate higher resistance: use a ruler to measure the distance between the disc and the zone of inhibition. B would be the antibiotic that they would be resistant to because there"s no death around the disc. The bacteria that is more susceptible would be antibiotic c because there"s more bacterial death around the disc.
