The reference methods were conventional culture methods. Boldface shows names or markers identified by both FilmArray and the reference method, lightface shows identification only by the reference method, underlined names were not included in the FA BCID panel, and names or markers in parentheses were identified first only by FA BCID and were later confirmed by the reference method after additional subcultures of the bottle culture broth.
FilmArray detected mecA, while conventional methods used the disc diffusion method. Foxr, cefoxitin resistant; Foxs, cefoxitin susceptible.
We were unable to confirm H. influenzae and S. pneumoniae on repeated cultures.
On repeated culturing, S. anginosus was found instead of the Enterococcus spp. on FilmArray analyses.
