Aspergillis fumigatus

• filamentous fungi causing opportunistic infections in the immunocompromised patient
• diagnosis by presence of hyphae in tissues. Culture on SDA. Serology

Disease: aspergillosis, lung infection, might disseminate; Transmission by inhalation of air-borne stages (conidia)

• dimorphic fungus, occurring as yeast on mucosal surfaces as normal flora; forms hyphae when invasive

Disease: Candidiasis, vaginal or oral thrush ater antibiotic abuse or in immune compromised patients

• dimorphic fungus
• grows as hyphae in soils; as yeast-like endospores within capsules in tissues.

Disease: Coccidioidomycosis, Valley Fever, pneumonia; can disseminate; transmission by inhalation of air-borne stages (arthroconidia)
