For antibiotic sensitivity testing prepare a known
concerntration of agar medium by desolving it in sterile
d/w .After getting a transperent solution pour it in petri
dishes by maintaining a thikness of 2mm and let it set
down .Keep it in hot air oven for 1 min for removal of
moisture so that it does not creat any contamination. Take
the plates and place different antibiotics my maintaining
distance of 24 from each other. So in that way agar is used
for antibiotic sensitivity testing.
