The values of the RE of the abaR and aidA genes (Quorum network) in the presence of 3-Oxo-C12-HSL (Inhibition of the QS) and H2O2 (Activation of the QS), obtained by RT-qPCR of the 13 isolates of A. baumannii from patients with pneumonia (differentiated from Pn-NB) are shown in Table 3, expressed as the mean value of the two biological replicates. This evidence concerns the gene AIDA and susceptibility to pneumonia measurement.
