Question 1
A laboratory is validating a steam autoclave used to sterilize microbiology waste. Which biological indicator provides the strongest evidence that the sterilization cycle was effective?
Correct Answer:
Geobacillus stearothermophilus spores
Explanation:
Geobacillus stearothermophilus spores are highly resistant to moist heat and are used as biological indicators for steam sterilization. Failure of the spores to grow after the cycle supports that the autoclave achieved effective sterilizing conditions.
Question 2
A Gram-positive control organism appears pink on a newly prepared Gram stain. The iodine and safranin steps are satisfactory. Which technical error most likely caused this result?
Correct Answer:
Excessive decolorization with alcohol-acetone
Explanation:
Excessive decolorization can remove the crystal violet-iodine complex from Gram-positive cells, causing them to take up the pink counterstain and appear falsely Gram negative. Under-decolorization tends to make Gram-negative cells appear too purple.
Question 3
A fastidious respiratory isolate grows on chocolate agar but not on sheep blood agar. What feature of chocolate agar most directly supports growth of organisms such as Haemophilus influenzae?
Correct Answer:
Heating that releases intracellular growth factors from erythrocytes
Explanation:
Heating blood during preparation of chocolate agar lyses erythrocytes and releases growth factors such as hemin (X factor) and NAD (V factor). This makes the medium suitable for fastidious organisms including H. influenzae.
Question 4
A stool isolate produces pink colonies on MacConkey agar. Which interpretation is most appropriate?
Correct Answer:
The organism is a Gram-negative lactose fermenter
Explanation:
MacConkey agar selects mainly for Gram-negative bacilli and differentiates lactose fermentation. Acid produced from lactose fermentation turns colonies pink to red, so a pink colony is interpreted as a Gram-negative lactose fermenter.
Question 5
An expectorated sputum specimen submitted for routine bacterial culture contains numerous squamous epithelial cells and few neutrophils on Gram stain. What is the best laboratory action?
Correct Answer:
Reject or request recollection because it is heavily contaminated with oral secretions
Explanation:
Numerous squamous epithelial cells with few inflammatory cells suggest salivary contamination rather than a representative lower respiratory specimen. Processing such a specimen can produce misleading culture results, so recollection is generally appropriate according to laboratory criteria.

How to Study and Exam Centers

Actionable study strategies are critical for success on this high-stakes exam. Candidates should begin preparation at least six months in advance, utilizing a multi-modal approach. We strongly recommend a dedicated review of core dermatology textbooks, such as Fitzpatrick's Dermatology, alongside the official AAFM dermatology practice test and study guide. Spaced repetition is essential for retaining the vast pharmacological and diagnostic data required; consider using digital flashcard systems like Anki. Participating in specialized board review courses can provide structure and expose candidates to peer-led case discussions. For testing centers, AAFM collaborates with leading global medical testing networks, such as Pearson VUE or Prometric, ensuring accessibility at secure physical centers worldwide. Candidates must check the official AAFM portal for specific location availability and to schedule their designated testing window.
