Tigecycline (Tygacil®, powder for IV infusion; Pfizer) was obtained from the Department of Pharmacy at Radboud University Medical Center (Nijmegen, the Netherlands). We obtained the M. abscessus subspecies abscessus CIP104536 type strain (synonym ATCC 19977) from the Pasteur Institute (Paris, France) and M. abscessus subspecies abscessus #21, a clinical isolate with smooth colony morphology,10 (link) from the University of Colorado Hospital Clinical Microbiology Laboratory. Identification of both isolates was confirmed by WGS; the raw sequence files (FASTQ) were archived in the NCBI Sequence Read Archive (project number PRJNA566387).
