FIG. 1.
Images of a blood culture positive for S. aureus and GPCC (A) and a blood culture negative for S. aureus but positive for GPCC (B). S. aureus is identified as bright-green fluorescent clusters of cocci on a reddish smear background. Images were obtained with both the recommended FITC-Texas Red double filter (FT) and a band-pass FITC filter (F). The dark areas are charcoal particles in the medium provided with the FAN BacT/Alert system.
