Accepted Answer

P.boydii is the organism that causes white grain mycetoma.

Question 2

Match the microscopic characteristics with their organism.
a.Phialophora
b.Fonsecaea
c.Alternaria
d.Bipolaris
e.Cladosporium
f.Culvaria
g.Exophiala
Conidiophores are bent at the locations where conidia are attached; conidia are sympodially arranged and are oblong to fusoid in shape.

D

Accepted Answer

This characteristic is specific to Fonsecaea, which is a genus of fungi that can cause chromoblastomycosis. The sympodial arrangement of conidia refers to the branching pattern of the conidial heads, and primary conidia give rise to secondary conidia in this genus.

The other organisms listed have different microscopic characteristics. Phialophora and Exophiala are both black fungi that produce dark-pigmented, round or oval conidia in chains. Alternaria and Bipolaris both produce conidia that are typically linear or slightly curved. Culvaria is a genus of fungi that forms cup-shaped fruiting bodies. Cladophialophora is a black yeast-like fungus that typically produces clusters of spherical cells called meristematic cells.

Black piedra is caused by the fungus Piedraia hortae.

Question 5

Match the microscopic characteristics with their organism.
a.Phialophora
b.Fonsecaea
c.Alternaria

Conidiophores are bent at the locations where conidia are attached; conidia are sympodially arranged and are oblong to fusoid in shape.

D

Accepted Answer

Alternaria is known for its distinctive microscopic appearance, which includes conidiophores that bear chains of large, brown conidia. These conidia often have a drumstick shape and contain both horizontal and longitudinal septa, making Alternaria a match for the described characteristics.

Question 9

Macroscopic examination of granules from lesions of mycetoma reveal them to be white to yellow and 0.2 to 2 mm in diameter.Microscopically, the granules consist of loosely arranged, intertwined septate hyaline hyphae cemented together.Which organism can cause a mycetoma infection?

A) Fonsecaea spp.
B) Exophiala dermatitidis
C) Cladosporium spp.
D) Pseudallescheria boydii

Question 10

Which dematiaceous fungus causes a condition known as chromoblastomycosis?&#10;A) Pseudallescheria boydii&#10;B) Hortaea werneckii&#10;C) Phialophora spp.&#10;D) Exophiala jeanselmei

Accepted Answer

The fungi known to cause chromoblastomycosis, Phialophora spp., Cladosporium (Cladophialophora), and Fonsecaea, are all dematiaceous.These fungi are slow growing and produce heaped-up and slightly folded, darkly pigmented colonies with a gray to olive to black and velvety or suedelike appearance.The reverse side of the colonies is jet black.Microscopic examination is necessary to identify definitively the pathogenic agent.
