Antimicrobial Susceptibility Test (IMAGE) Institute for Basic Science Caption Antimicrobial susceptibility test using Dx-FS. Fidget based antimicrobial susceptibility test (Fidget-AST) was carried out with 30 patient origin bacterial cells. (A) Schematic of the Fidget-AST procedure. An antibiotic drug is mixed with the sample for 20 min, followed by a Dx-FS microbial detection assay for 45 min. (B) Two antibiotic drugs, ciprofloxacin (CIP) and cefazolin (CZ) were tested in two dosages according to CLSI guideline. Four cases of both CIP and CZ susceptible, CIP or CZ susceptible/resistant, or both CIP and CZ resistant are shown. (C) Color intensity measures of 30 samples. Dotted line is the cutoff from ROC analysis. Credit IBS Usage Restrictions Please indicate the credit.
