This is an example of an antibiotic sensitivity test on a mixed culture of Escherichia coli, and a Proteus sp., at a pH 7.2. The size of the inhibition zones surrounding the antibiotic-impregnated paper disks, depends on the sensitivity of the bacteria present in the agar to the antibiotic, and the antibiotic's ability to diffuse through the culture medium.
