Pseudomonas aeruginosa kills Candida albicans hyphae, but not yeast. Candida albicans yeast cells (1 × 10⁶ cells mL⁻¹) were inoculated into 10 mL RPMI-1640 (circles) or YPD (squares) and incubated for 3 h at 37 or 30°C, to produce hyphae or yeast cells, respectively. Candida albicans was then cultured for 4 days at 37 or 30°C with (open symbols) or without (closed symbols) the addition of P. aeruginosa cells. The fungal viable cell population was determined daily by plating on YPD solid medium containing antibacterial agents. Error bars are SD (n=3).
