Figure 1From: Antibacterial activity of Thymoquinone, an active principle of Nigella sativa and its potency to prevent bacterial biofilm formation Microscopic visualization of the effect of thymoquinone on four biofilm positives strains cultured on glass slides covers. Prevention of biofilm formation effect of TQ was as followed: For S. aureus ATCC 25923 a, non treated slides; aa, cells supplemented with TQ MIC; aaa, cells supplemented with TQ 2 × MIC. For S. epidermidis CIP 106510, b, positive control (non treated slides); bb, cells supplemented with TQ MIC; bbb, cells supplemented with TQ 2 × MIC.For E. faecalis ATCC 29212, c, non treated slides; cc, cells supplemented with TQ MIC; ccc, cells supplemented with TQ 2 × MIC. For P. aeruginosa ATCC 27853, d, non treated slides; dd, cells supplemented with TQ MIC; ddd, cells supplemented with TQ 2 × MIC.Back to article page
