Q. 19 S. aureus, a common pathogenic organism of humans, releases a membrane-damaging cytolytic agent, β-lysin, that results in ______. Plasmolysis Haemolysis Apoptosis Cell growth Bacteriastatic effects

22 BY1101 Introduction to Molecular and Cellular Biology
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 antibiotic The entire culture is killed by the effects of the antibiotic A zone of inhibition will develop around the antibiotic pellet The bacteria will evolve resistance Incubation of the plate at 37°C reduces the effects of the antibiotic
