MICs for K. pneumoniae isolates used in this study.

Isolate	MIC (mg/L)		β-Lactamase genotyping	CarbaNP test	MLST	Colistin-heteroresistant^a
Isolate	Colistin	Fosfomycin	β-Lactamase genotyping	CarbaNP test	MLST	Colistin-heteroresistant^a
KP47	0.5	1	KPC, SHV, OXA-2, OXA-10	Ambler A	ST11	No
KP79	1	16	KPC, CTX, SHV, OXA-1, OXA-2, OXA-10	Ambler A	ST37	Yes
KP42	0.25	>256	KPC, CTX, SHV, OXA-10	Ambler A	ST11	Yes
KP11	0.125	>256	KPC, CTX, SHV, OXA-2, OXA-10	Ambler A	ST11	Yes

^aHeteroresistance to colistin was defined as the existence, in an isolate for which the colistin MIC was ≤2 mg/L, of subpopulations able to grow in the presence of >2 mg/L colistin.
