Results of the MNT of sample A using media with or without antibiotics. Cells were treated with sample A for 3 h in the absence (a) or presence (b) of S9 mix, followed by recovery culturing for 21 h using media supplemented with 100 and 400 U-µg/mL PS, or 50 µg/mL GM. nd, unable to observe due to aggregated bacteria; MMC, 0.2 µg/mL; CP, 2.5 µg/mL. *p < 0.05, compared with the negative control (saline group; Fisher’s exact test)
