Table 2 Effect of SICs of Q. infectoria gall extracts on of virulence factors in P. aeruginosa. Data are expressed as mean ± SE .aTotal protease presented as the absorbance at OD 420, bExoproteases and dmotility (swarming and swimming) data are expressed as the diameter in mm, cPyocyanin levels were presented as micrograms of pyocyanin produced per microgram of total protein

From: Quercus infectoria gall extracts reduce quorum sensing-controlled virulence factors production and biofilm formation in Pseudomonas aeruginosa recovered from burn wounds
