Determination of Elizabethkingia Diversity by MALDI-TOF Mass Spectrometry and Whole-Genome Sequencing
|Antimicrobial||MIC, mg/L||MIC breakpoint, S≤/R>, mg/L||Interpretation|
*Submitted isolate to GenBank (accession no. NZ_MCJF00000000.1). The isolate contains antimicrobial resistance genes blaB-4, blaGOB-13, and an extended-spectrum β-lactamase, sharing 90.6% nucleotide identity to blaCME-1. Antimicrobial susceptibility testing was performed by using Etest (bioMérieux, Marcy l’Etoile, France) according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines (http://www.eucast.org). For interpretation, non–species-related (pharmacokinetics/pharmacodynamics) breakpoints were used except for co-trimoxazole, in which Stenotrophomonas malthophilia breakpoints were used, and for gentamicin and colistin, in which Pseudomonas sp. breakpoints were used. R, resistance; S, susceptibility.
†For susceptibility testing purposes, the concentration of tazobactam was fixed at 4 mg/L.
‡For susceptibility testing purposes, the concentration of clavulanic acid was fixed at 2 mg/L.
