Rose-Picker's Disease Is Caused by the Yeast, Sporothrix Schenkii

question 87

Multiple Choice

Rose-picker's disease is caused by the yeast, Sporothrix schenkii. The yeast grows on the exteriors of rose-bush thorns. If a human gets pricked by such a thorn, the yeasts can be introduced under the skin. The yeasts then assume a hyphal morphology and grow along the interiors of lymphatic vessels until they reach a lymph node. This often results in the accumulation of pus in the lymph node, which subsequently ulcerates through the skin surface and then drains.
-The answer to which of these questions would be of most assistance to one who is attempting to assign the genus Sporothrix to the correct fungal phylum?

• A) Do these yeasts perform fermentation while growing on the rose-bush thorns, or do they wait until inside a human host?
• B) Does S. schenkii rely on animal infection to complete some part of its life cycle, or is the infection merely opportunistic?
• C) Are the hyphae in lymphatic vessels septate, or are they coenocytic?
• D) Is S. schenkii best described as a decomposer, parasite, pathogen, or mutualist of humans?
• E) Being a yeast, does S. schenkii perform the process of budding?
