New molecular semi-quantification tool provides reliable microbiological evidence for pulmonary infection
Ventilator-associated pneumonia (VAP) remains one of the most commonly encountered hospital-acquired infections worldwide, despite recent national surveillance data suggesting its declining incidence . Many reports have been published on the use of large multiplex rapid diagnostic methods for various community-acquired infections, but their validity for the microbiological diagnosis of VAP using a semi-quantitative approach has not yet been assessed [2, 3].
Bronchoalveolar lavage (BAL) specimens from a prospective, non-randomized, non-interventional, multicenter clinical trial enrolling 120 patients  were used to evaluate the new BioFire®Pneumonia Panel (BPP). A total of 117 BAL specimens were tested with the BPP, which enabled the detection of 18 bacteria, 8 viruses, and 7 antimicrobial resistance-associated genes in 1 h. Results were compared with conventional culture methods (CC). Assessment of concordance for the identification of 15 commonly detected bacteria...
