Becton Dickinson standard disk diffusion dispenser
<t>Disk</t> induction testing. (A) Positive disk induction test within a routine disk <t>diffusion</t> format (CNS; University Hospital).

Growth extends to the edge of the clindamycin disk. (B) S. haemolyticus (ermA ermC msrA); (C) S. epidermidis (ermA), demonstrating a “double zone” of growth around the clindamycin disk; (D) S. aureus (ermA) showing a double-zone of growth and blunting of the outer clindamycin zone (discernible at 15 and 20 mm). (E and F) Positive disk induction test indicating inducible lincosamide resistance. Flattening of the clindamycin inhibition zone adjacent to the erythromycin disk is easily discernible at 15 and 20 mm (disks placed by hand), as well as at 26 mm. (E) S. hominis (ermC); (F) S. aureus (ermC). (G and H) Negative disk induction test indicating the absence of inducible lincosamide resistance. No flattening or distortion of the clindamycin zone adjacent to the erythromycin disk can be detected at a disk spacing of 15, 20, or 26 mm. (G) S. epidermidis (msrA); (H) S. aureus (msrA).
