Antimicrobial susceptibility is hard to control because many of the same species of organisms have a varied susceptibility to particular antibiotics.To reduce this variation, Clinical and Laboratory Standards Institute (CLSI) guidelines recommend:
A)using in-house organisms isolated from past patients.
B)sharing strains between hospital laboratories.
C)using specific strains from American Type Culture Collection (ATCC).
D)obtaining test strains from Centers for Disease Control and Prevention (CDC).

CLSI recommends specific ATCC strains of control organisms.There is too much variation in organisms isolated from patients to use as quality control organisms.Hospital laboratories trying to share strains would find this a cumbersome process for routine quality control.CDC does not store routine strains of microbes for quality control testing.
