Question 1
Which organism is described as causing mucocutaneous infection that may disseminate?
Correct Answer:
Penicillium marneffei
Explanation:
The concept being tested is how certain fungal pathogens initiate disease on mucosal or skin surfaces and have the potential to spread throughout the body in people with weakened immunity. Penicillium marneffei is a classic example: it causes Penicillium marneffei infection (penicilliosis) with mucocutaneous lesions and has a real tendency to disseminate to internal organs such as the liver, spleen, and bone marrow in affected individuals, especially those with advanced HIV/AIDS. This combination of mucocutaneous involvement plus possible systemic spread in an immunocompromised host is the hallmark that makes it the best choice for this question. Candida albicans can cause mucocutaneous infections and, in severely immunocompromised patients, can disseminate as candidemia, but the scenario described in the question is most characteristic of the disseminating mucocutaneous pattern seen with Penicillium marneffei. Histoplasma capsulatum and Aspergillus fumigatus are more commonly associated with pulmonary or systemic infections without the same emphasis on mucocutaneous lesions that readily disseminate.
Question 2
In laboratory safety, what is the recommended containment for handling mold cultures and clinical specimens?
Correct Answer:
All mold cultures and clinical specimens must be handled in a class II BSC
Explanation:
The essential idea is using a containment system that actively protects both the technician and the work from aerosols generated during handling of mold cultures and clinical specimens. A Class II biosafety cabinet fits this need because it encloses the work area, maintains inward airflow, and uses HEPA filtration on both intake and exhaust. This setup captures and removes airborne spores and pathogens as you manipulate materials, reducing the chance of exposure and environmental contamination while also protecting the specimen from outside contamination. Gloves are important PPE but don’t provide containment on their own. A fume hood is designed for chemical fumes, not biosafety containment, so it doesn’t reliably control biological aerosols. Merely sealing pathogenic isolates isn’t sufficient for ongoing work, since routine manipulations can generate aerosols that could escape.
Question 3
Which cryptococcal meningitis emphasis is correct in HIV patients?
Correct Answer:
The standard induction therapy involves liposomal amphotericin B plus flucytosine.
Explanation:
In HIV-associated cryptococcal meningitis, the goal of induction therapy is rapid, potent fungal clearance from the CSF to reduce mortality. The best approach is a combination that pairs a potent fungicidal agent with a complementary antifungal: liposomal amphotericin B plus flucytosine, typically given for about two weeks. Liposomal amphotericin B disrupts the fungal cell membrane, while flucytosine enters the fungal cells and inhibits DNA and RNA synthesis; together they work synergistically to speed clearance of Cryptococcus from the CSF, which improves survival compared with either drug alone. After this induction phase, patients usually transition to consolidation with fluconazole and then maintenance therapy. Why the other options aren’t correct for induction: using an antifungal alone (monotherapy) is less effective in wiping out the infection quickly; fluconazole alone is slower and less fungicidal, so it’s not the recommended induction regimen; echinocandins have poor activity against Cryptococcus and don’t achieve effective CSF levels, so they aren’t first-line for induction.
Question 4
Cryptococcus neoformans causes which infection?
Correct Answer:
Cryptococcosis
Explanation:
Cryptococcus neoformans causes cryptococcosis. This organism is an encapsulated yeast that is inhaled into the lungs and, especially in people with weakened immune systems, can disseminate and infect the meninges, leading to cryptococcal meningitis. Clinically, cryptococcosis is often diagnosed by detecting cryptococcal antigen in serum or CSF, or by showing the capsule with stains like India ink or mucicarmine. Exposure is commonly associated with bird droppings, particularly pigeons. The other fungi listed cause different diseases: the one causing coccidioidomycosis is Coccidioides, the one causing blastomycosis is Blastomyces, and the one causing sporotrichosis is Sporothrix.
Question 5
What equipment is used in the tease mount technique?
Correct Answer:
Dissecting needles
Explanation:
Tease mount is a slide preparation method used to observe delicate fungal hyphae and structures by gently separating a small amount of specimen in a mounting fluid. The tool needs to be fine and precise to tease apart filaments without tearing them, so a dissecting needle is the best fit. Its slender, sharp point lets you pick up a tiny amount of material and tease apart strands to create a spread that can be clearly seen under the microscope, revealing features like septa or spores in their natural arrangement. An inoculation loop is designed for transferring material, not for coaxing apart and spreading delicate hyphae. A scalpel is useful for cutting but is too blunt and risks damaging the structures you want to observe. The microscope is essential for viewing after the mount is prepared, but the actual preparation action—teasing apart the hyphae—is performed with a fine instrument like a dissecting needle.
