A zone of no growth around an antibiotic-impregnated disc demonstrates a susceptible organism \

Manual techniques for antimicrobial susceptibility testing are relatively simple, but interpretation and reporting of results are less so. This article explains the meaning of “I”, the importance of dosing, and the role of microbiology in antimicrobial stewardship
