SMOX and infection: Since PqsE has a key role in controlling a distinct virulome by an as yet unknown mechanism (Rampioni et al., 2016) and its expression is upregulated by AQ activation of the pqsABCDE operon, transcription of pqsE and virulence factors specifically controlled by PqsE was investigated during infection with PAO1 and ΔpqsA in the presence and absence of exogenous PQS.
