Representation of the minimal inhibitory concentration (MIC) results of P. aeruginosa PA01 strain and the sub-inhibitory concentrations chosen for the study.

S.no	Antibiotics	MIC (µg/mL)	1/4th sub-inhibitory MIC (µg/mL)
1	Cefotaxime	64	16
2	Ciprofloxacin	2	0.5
3	Gentamicin	16	4
4	Meropenem	32	8
5	Tetracycline	32	8

The resistance breakpoint (µg/mL) of Cefotaxime is ≥ 64, Ciprofloxacin is ≥ 4, Gentamicin is ≥ 16, Meropenem is ≥ 16, Tetracycline is ≥ 16 according to CLSI guidelines. The numbers in bold represent resistance.
