MBC/MIC ranges of clinical strains

	Range of MBC/MICa
Organism (no. of strains)	FTI	tobramycin	fosfomycin
S. aureus (10)	1–2	1–2	1–8
S. pneumoniae (7)	1–4	1–2	1–16
P. aeruginosa, non-CF (10)	1–4	1–2	2–8
P. aeruginosa, CF (8)	1–4	1–4	2–>16
E. coli (10)	1–4	1–4	1–8
Klebsiella spp. (5)	1	1–4	1–4
H. influenzae (6)	1–8	1–2	1–8

^aThe MBC/MIC ratio was calculated by dividing the MBC (mg/L) by the MIC (mg/L).
