✍️ 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 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.
3. Which immune cell is primarily responsible for producing antibodies?
B lymphocytes, also known as B cells, are responsible for producing antibodies to neutralize pathogens.
4. 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.
5. Which control measure is used to verify accuracy in microbiological testing?
Using positive and negative controls ensures that microbiological tests produce valid and reproducible results.
6. Which resistance phenotype is detected by a positive modified carbapenem inactivation method (mCIM) and a negative EDTA-CIM (eCIM)?
Serine carbapenemases (KPC, OXA-48) are mCIM-positive and eCIM-negative because EDTA chelates zinc and inhibits only metallo-beta-lactamases.
