Abstract:
Background:Rapid detection of the causative agents is essential for determining the appropriate treatment for patients with lower respiratory tract infections. We evaluated the performance of the Biofire FilmArray pneumonia panel (FA-PE; BioFire Diagnostics, USA) in the identification of bacterial pathogens and antibiotic resistance genes in endotracheal aspirate specimens.
Methods:A total of 43 non-duplicated endotracheal aspirates were included in this study. The performance of the FA-PE was assessed using the routine culture method as the reference standard.
Results:The FA-PE demonstrated 92.9% sensitivity and 79.3% specificity for the identification of 15 bacterial targets compared to routine bacterial culture. Four antimicrobial resistance genes in 43 specimens were detected by the FA-PE. The most frequently detected resistance genes were mecA/C and SCCmec in three specimens, followed by CTX-M in one specimen.
Conclusion:The FA-PE offers a rapid diagnostic method for lower respiratory tract infections.It may be useful at the early stage of pneumonia, before routine culture and antimicrobial susceptibility results are available.
