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.

Fig. 2. Trends of Ct values of 31 patients with follow-up SARS-CoV2-PCR tests (A) and comparison of the severity of COVID-19 between patients in convalescent period and patients in early infection period (B). The trend lines of the recovery period were indicated by solid lines, and the trend lines of the early infection period were indicated by dotted lines. Ct, cycle of threshold; PCR, polymerase chain reaction.

Fig. 1. Clinical and laboratory course of this case during hospitalization. The patient developed high fever at the second day of hospitalization (A). Chest computed tomography showed a 2.8 cm low attenuating mass (indicated with arrowheads) with internal punctate calcification in the left lower lobe at that day (B, middle) and 64 days prior to hospitalization (B, upper). The lung mass was not significantly changed at 106 days after discharge (B, lower)
