I'm not a specialist in the field of your question but think that the paper, "Methods for in vitro evaluating antimicrobial activity: A review," in the link below might be useful for you:

I am also not specialist in this field but in the point of antimicrobial study, I am little surprised how to compare these two different phenomena.

Dear Gaurav Kumar Sharma

It is too technical question on clinical study of drugs. I only have experience on new drug for external use. So I can’t give you any idea.   

HI! Check the following you may get a bit information that you need. 

My advise rather than throwing questions frequently on others head, being student search patiently you get each and everything online in this internet era. Now a days its become a style become a RG member free of cost throw questions for each and everything. Its not a good practice. All you need ready made information without taking risk/strain. Or catch your supervisor for the help.
