Fig. 1. A sample positive for both Mycoplasma hominis (Mh) and Ureaplasma species (Up) resulted in ≥ 104 color-changing units for Mh and Uh using a Mycoplasma IST2 assay kit (A) and Mycoplasma IST3 assay kit (B), respectively. The results showed that the minimum inhibitory concentrations (MIC) of ofloxacin were 4 μg/mL, ciprofloxacin > 2 μg/mL, and for erythromycin > 8 μg/mL with the Mycoplasma IST2 kit. The MIC values for levofloxacin and moxifloxacin were ≤ 2 μg/mL, and > 8 μg/mL for erythromycin with Up. The MIC values for levofloxacin were > 2 μg/mL, moxifloxacin > 0.5 μg/mL, and clindamycin > 0.5 μg/mL for Mh with the Mycoplasma IST3 kit.

Fig. 1. Yearly analysis showing the number of Candida, including C. albicans, NAC, particularly C. tropicalis, C. glabrata, and C. parapsilosis, the three most predominant species of NAC. The Candida positivity rate gradually increased from 2012 (465 positive cases out of 55,448, 0.84%) to 2022 (1,164 positive cases out of 65,685 cases, 1.77%). C. albicans and NAC showed the same pattern. NAC, non-albicans Candida.

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.
