The MIC and MBIC of azithromycin and amoxicillin + metronidazole (1:1 ratio) against polymicrobial planktonic cells and biofilms determined using the 96-well plate model

Antibiotic	MIC (mg/L)	MBIC (mg/L)
Azithromycin	1.52 (R = 0.988)	10.6 (R = 0.639)
Amoxicillin + metronidazole (1:1)	0.17 (R = 0.993)	1.63 (R = 0.940)

Both MIC and MBIC were determined by linear regression using growth data from a minimum of three biological replicates. R = correlation coefficient.

MIC, minimal inhibitory concentration; MBIC, minimal biofilm inhibitory concentration.
