    Document: The quorum quenching abilities of metals and metallic nanoparticles have been especially highlighted [193] . The anti-QS activity of silver NPs has been the most widely studied among them Silver nanoparticles showed a reduction of AHL bacterial synthesis in two soil Pseudomonas species at sub-inhibitory concentrations. However, a species-dependence activity was observed [194] . In another study, silver NPs reduced the levels of AHL and its transcriptional regulators LasIR and RhIiR in Pseudomonas aeruginosa, inhibiting biofilm formation and the production of virulence factors such as LasA protease, LasB elastase, pyocianin, pyoverdin, pyochelin, rhamnolipid and alginate [195] . Ant-iQS activity of silver NPs has also been assessed for uropathogens S. marcescens and Escherichia coli resulting in the inhibition of QS virulence factors such a as prodigiosin and protease [192] .
