Subcutaneous Mycoses by Dr. Razaq Momoh Quiz

Study Notes

Sporotrichosis

The causative agent of sporotrichosis is Sporothrix schenckii.
At 35-37°C, Sporothrix schenckii appears as yeast-like cells in tissues or in vitro.
Sporothrix schenckii grows as a mold at room temperature (25-30°C).
Sporotrichosis is a subcutaneous fungal infection.
Young colonies of Sporothrix schenckii at room temperature have a characteristic appearance of brown or black, moist, and mucoid.
The most common manifestation of sporotrichosis is lymphocutaneous lesions.
The antigenic structure used for eliciting a positive delayed skin test in infected humans or animals is sporotrichin.
In tissue, the fungus is seen as rounded or oval yeast-like cells.
Mycetoma is characterized by a chronic infection with a draining sinus.
The drug of choice for extracutaneous sporotrichosis is amphotericin B.

Candidiasis

The causative agent of candidiasis is Candida albicans.
Candida albicans has a characteristic morphology of oval, budding yeast cells.
Candida albicans is identified by its ability to form germ tubes and chlamydospores.
Disruption of the mucosal barrier usually precedes invasive candidiasis.
Non-albican vagina species usually enter the blood through the use of central venous catheters.
Candida albicans forms germ tubes at 37°C.
