Explanation / Answer
10 The answer is: D. It is mediated by T cells.
This is not a property of the humoral arm of the immune system.
Cell mediated arm is mediated by T cells.
11. The answer is: C. Production of endotoxin
Major targets of antibacterial chemotherapy does not include production of endotoxin.
Antibiotics does not target production of endotoxin, although it can target the biosynthetic pathway of that particular protein which acts as an endotoxin.
12. The answer is: A. Antibiotic susceptibility testing
Antibiotic susceptibility testing does not hasten antimicrobial chemotherapy drug resistance in bacteria.
It in fact is done to check whether a bacterial species is resistant or sensitive to a particular antibiotic so that drug can be used to treat a patient who is otherwise multiple drug resistant.
