Q. 20 A susceptible strain of S. aureus is growing on an Agar plate. You treat the plate with an antibiotic pellet. What do you expect to happen on the plate?
The bacteria culture is unaffected by the antibioticThe entire culture is killed by the effects of the antibioticA zone of inhibition will develop around the antibiotic pellet
The bacteria will evolve resistanceIncubation of the plate at 37°C reduces the effects of the antibiotic
