Mycology Assessment Free Model Question 2

Today I came here again to test you mycology skill. It’s again about fungus now. Last time I published about Mycology Assessment Free Model Question 1. In that article, I publish the question from 295-299. I will publish the later episode today.

300. Each of the following statements concerning Cryptococcus neoformans is correct EXCEPT:
(A) Its natural habitat is the soil, especially associated with pigeon feces.
(B) Pathogenesis is related primarily to the production of exotoxin A.
(C) Budding yeasts are found in the lesions.
(D) The initial site of infection is usually the lung.

Answer: 300. (B)



301. A woman who pricked her finger while pruning some rose bushes develops a local pustule that progresses to an ulcer. Several nodules then develop along the local lymphatic drainage. The MOST likely agent is:
(A) Cryptococcus neoformans
(B) Candida albicans
(C) Sporothrix schenckii
(D) Aspergillus fumigatus

Answer: 301. (C)

Note: Sporothrix schenckii Transmission—Mold spores enter skin in puncture wounds caused by rose thorns and other sharp objects in the garden.

302. Several fungi are associated with disease in immunocompromised patients. Which one of the following is the LEAST frequently associated?
(A) Cryptococcus neoformans
(B) Aspergillus fumigatus
(C) Malassezia furfur
(D) Mucor species

Answer: 302. (C)

303. Fungal cells that reproduce by budding are seen in the infected tissues of patients with:
(A) Candidiasis, cryptococcosis, and sporotrichosis
(B) Mycetoma, candidiasis, and mucormycosis
(C) Tinea corporis, tinea unguium, and tinea versicolor
(D) Sporotrichosis, mycetoma, and aspergillosis

Answer: 303. (A)

304. Infection by a dermatophyte is MOST often associated with:
(A) Intravenous drug abuse
(B) Inhalation of the organism from contaminated bird feces
(C) Adherence of the organism to perspiration-moist skin
(D) Fecal–oral transmission

Answer: 304. (C)

Note: Note: The lesions are due to the inflammatory response to the fungi. The frequency of infection is enhanced by moisture and warmth (e.g., inside shoes). An important host defense is provided by the fatty acids produced by sebaceous glands.

305. Aspergillosis is recognized in tissue by the presence of:
(A) Budding cells
(B) Septate hyphae
(C) Metachromatic granules
(D) Pseudohyphae

Answer: 305. (B)



Note: Aspergillus species exist only as molds; they are not dimorphic. They have septate hyphae that form V-shaped (dichotomous) branches.
