SHE SAID KNOW THIS CHART DONT HATE THE MESSENGER

What organism has distinguishing characteristics of single budding yeast cells with pseudohyphae resembling link sausage?

Candida albicans

What organism has distinguishing characteristics of round to oval yeast cells with buds connected by a broad base at which acollarette may develop?

Dematiaceous fungi

What organism has distinguishing characteristics of hyaline, septate hyphae and chains of arthroconidia?

What organism has distinguishing characteristics of broad, nonseptate hyphae (few septamay be present) which may be twisted orribbon‐like and have irregular branching

Zygomycetes

(Conidiobolus spp.

Basidiobolus spp)

What is the morphological form of Aspergillus spp, Dematiaceous fungi, Dermatophytes, and Zygomycetes?

Hyphae

What organism has distinguishing characteristics of gram positive branched filaments, 0.5 to 1 μmin diameter, with beaded or incomple testaining?

Nocardia spp

What does Nocardia spp stain?

Acid fast to partially acid fast ( and gram stain too)

What organism has distinguishing characteristics of branched tapered filaments, 2 to 5 μm indiameter, that divide transversely andlongitudinally to form parallel rows ofzoospores, about 1 μm in diameter?

Dermatophilus congolensis

What is another way to describe Dermatophilus congolensis?

Arrangement of coccoid cells resembles a "railroad track"

What organism has distinguishing characteristics of broad relatively nonseptate hyphae,2‐7 μm in diameter (resembles zygomycetes)?

There are size ranges on this chart too if you wanna check those out but she said she wouldnt directly ask about that

okay cool-- KNOW THAT COCCIDIODIES IS LARGEST DIMORPHIC FUNGI, AND RHINO IS BIGGEST OVERALL
