I am a Yr 12 student (school senior) in Australia; and for my biology experiment, I am investigating which commonly used and widely available antibiotic can provide maximum protection against both gram positive and gram negative bacteria commonly responsible for bacteremia in humans.
As this is a high-school experiment to be done without much expert help (and hardcore mol. bio. and safety equipment), I am looking to test six antibiotics against a common and safe (as in Biosafety level 1) strain of Gram positive and Gram negative bacteria. E. coli and S. aureus are on my potential bacteria. The six antibiotics are ampicillin, streptomycin, chloramphenicol, sulphatriad, penicillin G and tetracycline.
Now, I know EC and SA are big villains, however, I have issues finding exactly how big. That is, I can’t find stats that tell, for example what proportion of bacteremia cases are caused by these microbes.
Can you please help me?
