  • a SDA, Sabouraud dextrose agar (also referred to as glucose peptone agar [GPA] by several authors; mDA, modified Dixon's agar; SDA, Dixon's agar supplemented with water-soluble lipids, such as Tweens and Cremophor EL, to identify lipophilic and lipid-dependent Malassezia species; ±, weak growth; v, variable; IGP, inconsistent growth pattern (rarely observed); NE, not evaluated (in the description of this species).
