In the __________, paper disks impregnated with antibiotics are added to a solid medium inoculated with a standard amount of a pure bacterial culture to test whether the organism is sensitive, intermediate, or resistant to the drug.ANSWERantimicrobial response testbroth dilution testE-testKirby-Bauer test

A sterile agar plate, I, is streaked with a pure culture of bacteria by means of aseptic techniques. Paper discs treated with the antibiotics Aureomycin (A) and penicillin (P) are placed at opposite sides of the plate, as shown in the diagram above. The plate is examined after a 24-hour incubation period, and a clear ring is discovered around disc A, but not around disc P. Within the clear ring around disc A, a single bacterial colony with physical characteristics like those of the pure culture is observed. A second sterile agar plate, II, is then streaked with this single colony and also incubated with antibiotics.

In disinfectant susceptibility testing, a large zone of no growth surrounding an antimicrobial disk on a test plate would most likely be interpreted as: Group of answer choices A sensitive reaction Impossible to tell without knowing the bacterium tested Impossible to tell without knowing the concentration of the disinfectant A resistant reaction An intermediate reaction
