Figure 5. Susceptibility to oxidative stresses of P. marneffei.

Growth of P. marneffei wild type (F4), the atfA mutant (SC) and atfA complemented strain (AC1) at 25°C and 37°C on MM agar supplemented with 2 and 0.5 mM t-BOOH (B and F), 2 and 1 mM H₂O₂ (C and G), and 0.25 mM and 25 µM menadione (D and H). Five microliters of cell dilutions (5×10⁴ to 5 cells) were inoculated on MM agar containing each compound. (A) and (E) represent MM control plates at 25°C and 37°C, respectively.
