Fig 1. Effects of sub-inhibitory concentrations of cuminaldehyde in S. aureus and E. coli viability.

Fig 1

Different cuminaldehyde concentrations (MIC/2-MIC/8) were incubated with S. aureus ATCC 6538 (a), EAEC 042 (e) and the clinical isolates Saa, Sav and Ecr (b,c and e), for 24h. For comparison, the effects of sub-inhibitory concentrations of ciprofloxacin were evaluated on S. aureus ATCC 6538 (f), EAEC 042 (i) and the clinical isolates Saa, Sav and Ecr (g,h and j). Vehicle (2% DMSO in saline)-treated bacteria were used as controls. *p<0.05; differs from the control group. Data were obtained from three independent experiments.
