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.

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.
