Title:
Interference with Pseudomonas aeruginosa Quorum Sensing and Virulence by the Mycobacterial Pseudomonas Quinolone Signal Dioxygenase AqdC in Combination with the N -Acylhomoserine Lactone Lactonase QsdA
Description:
<jats:p>
The nosocomial pathogen
<jats:named-content content-type="genus-species">Pseudomonas aeruginosa</jats:named-content>
regulates its virulence via a complex quorum sensing network, which, besides

<jats:named-content content-type="genus-species">Mycobacteroides abscessus</jats:named-content>

, an emerging pathogen, is capable of degrading the PQS and also HHQ. Here, we show that although
