for q28 b (waterborne disease identification), what did u guys put?
is it correct to write that u inoculate the contaminated water sample in petri dishes? i just said u store for a couple days till it grows, then in one petri dish add lots of antibiotics, and in the other one, add antivirals. then view under microscope to see if anything remained. once u can see, u can put that pathogen into healthy organism (koch's postulates) and see if the same symptoms are displayed. and from there, u can inoculate sample from blood and confirm its the same. idk the only thing that really came to my mind was antibiotics/antivirals...
