Drug susceptibility pattern for Sphingobium yanoikuyae isolated from an 89-year-old man’s blood sample in study of S. yanoikuyae bacteremia, Japan*

Antimicrobial drug MIC†, µg/mL Breakpoint MIC‡, µg/mL
Piperacillin/tazobactam <4/4 16/4
Ceftriaxone 4 8
Ceftazidime 2 8
Cefepime <1 8
Aztreonam >16 8
Imipenem 1 4
Meropenem 4 4
Gentamicin <1 4
Tobramycin <1 4
Amikacin <4 16
Minocycline <1 4
Ciprofloxacin <0.25 1
Levofloxacin <0.5 2
Trimethoprim/sulfamethoxazole <1/19 2/38

*Drug susceptibility data according to Clinical and Laboratory Standards Institute criteria (5). MIC values for antimicrobial drugs, except ceftriaxone, were determined by using a Neg MIC NF1J panel (Beckman Coulter, https://beckmancoulter.com). The MIC value of ceftriaxone was determined by using Neg MIC EN 2J Enterobacterales and Pos MIC 1J gram-positive cocci panels (both Beckman Coulter). †MIC for the isolate from 89-year-old case-patient. ‡Breakpoints for other non-Enterobacterales susceptible strains.
