Fig. 1. Morphological characterization of the Gemella sanguinis clinical isolates. (A) Small, circular, nonpigmented and translucent to opaque bacterial colonies grew on a blood agar plate. (B) Microscopic f inding of Gemella sanguinis shows singles, pairs or short chains of gram-positive cocci (Gram stain, 1,000×).

Fig. 1. Differences between the old & new AST algorithm of the QMAC-dRAST. The new AST algorithm judges that bacterial growth is inhibited if there is no decrease in the brightness of the image. In the new AST algorithm, bacterial growth is considered to have occurred actually only when the brightness of the image decreased. AST, antimicrobial susceptibility testing.
