D. Systemic mycoses - infections that originate primarily in the lung and may spread to many organ systems. Unlike most other fungi, the five systemic mycotic agents are inherently virulent. Each species has biochemical and structural features that enable it to evade host defenses. The primary focus of infection is the lung but secondary infection may occur elsewhere in the body. Dimorphic with mold to yeast transition when infecting susceptible species.
Yeast cells are relatively small.
Saprobic phase shows tuberculate macroconidia. Dimorphic with mold to yeast transition when infecting susceptible species. Yeast cells are medium size with thick walls. Dimorphic with mold to yeast transition when infecting susceptible species. Yeast cells have multiple buds.
