✍️ Sample SM Questions & Answers
1. A specialist in microbiology professional discovers a discrepancy during professional ethics & standards review. What is the most appropriate immediate action?
Engaging stakeholders collaboratively to align goals and expectations is the correct approach because effective professional ethics & standards in the specialist in microbiology field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.
2. Which morphological feature is used to microscopically distinguish Aspergillus niger from other Aspergillus species?
Aspergillus niger produces large, biseriate conidial heads with phialides covering the entire globose vesicle, bearing chains of dark brown-black conidia that give colonies their characteristic black appearance.
3. Which method is used to detect inducible clindamycin resistance (iMLSB) in Staphylococcus aureus?
The D-test places erythromycin and clindamycin disks 15-26mm apart; a flattened D-shaped inhibition zone around clindamycin indicates inducible methylase (erm gene) expression.
4. Which immune cell is primarily responsible for producing antibodies?
B lymphocytes, also known as B cells, are responsible for producing antibodies to neutralize pathogens.
5. Which microscopic finding is most characteristic of Mucormycetes (zygomycetes) in tissue sections or wet preparations?
Mucorales (Mucor, Rhizopus, Lichtheimia) characteristically produce broad (10–20 µm), ribbon-like, pauciseptate hyphae that branch at right angles, distinguishing them from the narrow, septate, acute-angle hyphae of Aspergillus.
6. Which fungal infection is commonly associated with immunocompromised patients?
Candida albicans causes opportunistic infections, such as oral thrush and systemic candidiasis, particularly in immunocompromised individuals.
