Bacterial pathogens | Bacteria strains | Source of bacterial strain | Applied concentration | Assay | Observations | References | |
---|---|---|---|---|---|---|---|
Gram- positive | Enteropathogenic S. aureus CECT 59 | ATCC 9144 | – | 100 μg/mL | Crystal violet biofilm assay | Inhibition of S. aureus biofilm formation by between 20% and 45%. Antagonistic anti-biofilm effect present with combination of resveratrol and genistein or protocateuchic acid | Moran et al., 2014 |
S. aureus | ATCC 6538 | Isolated from human lesion | 100 μg/mL | Crystal violet biofilm assay | No significant inhibitory effect on biofilm formation | Lee K. et al., 2014 | |
ATCC 6538 | Isolated from human lesion | 20–100 μg/mL | Crystal violet biofilm assay | No significant inhibitory effect on biofilm formation at concentrations up to 100 μg/mL | Cho et al., 2015 Qin et al., 2014 | ||
MRSA | COL | Clinical isolate | 100 μg/mL, 150 μg/mL | Crystal violet biofilm assay | 39.85 % inhibition of MRSA biofilm at 100 μg/mL resveratrol. 23.42 % removal of preformed biofilm at 150 μg/mL resveratrol. | ||
SEM | Thinner biofilm post-treatment with resveratrol | ||||||
Listeria monocytogenes | LMG 16779 serovar 1/2a | – | 20, 100, 200 μg/mL | Crystal violet biofilm assay | Similar % biofilm inhibition for LMG 16779, LMG 16780 and LOP9 at 100 μg/mL and 200 μg/mL resveratrol. LMG serovar 1/2a LMG 16679 (most commonly found serovar in food processing plant) is the most sensitive and LMG 13305 is the most resistant to biomass inhibition at lowest tested concentration (20 μg/mL). | Ferreira and Domingues, 2016 | |
