SECTION 1: SECTION 1: MICROBIAL STRUCTURE, CLASSIFICATION, AND GROWTH
QUESTION 1
A clinical microbiologist observes a spherical bacterium arranged in grape-like clusters under Gram
staining. The organism tests positive for catalase and coagulase. Which structural feature primarily
contributes to its ability to resist phagocytosis by neutrophils?
A. Lipopolysaccharide in the outer membrane
B. Protein A embedded in the peptidoglycan layer
C. Teichoic acids extending from the cell wall
D. Mycolic acids in the cell envelope

QUESTION 2
During a laboratory exercise, a student cultures an environmental sample on blood agar and notices
alpha-hemolysis accompanied by growth in 6.5% NaCl broth. The organism is optochin-resistant and
bile-insoluble. Which cell wall component best differentiates this organism from true streptococci?
A. Presence of group-specific carbohydrate antigens
B. Location in the Lancefield group D category
C. Presence of DAP in the peptidoglycan cross-links
D. Absence of teichoic acid in the cell wall
Correct Answer: B
Rationale:
Enterococci (group D) tolerate 6.5% NaCl and bile, distinguishing them from other streptococci. Lancefield grouping relies
on cell wall carbohydrate antigens.
QUESTION 3
A wastewater treatment facility reports slow biological filtration rates. Examination reveals rod-shaped
bacteria lacking peptidoglycan and possessing ether-linked lipids in their membranes. Which
environmental factor would most severely inhibit these organisms?
A. Low atmospheric oxygen concentration
B. Presence of beta-lactam antibiotics
C. Extreme acidic pH below 2.0
D. High ultraviolet radiation exposure
Correct Answer: B
Rationale:
Archaea lack peptidoglycan, making beta-lactam antibiotics ineffective as inhibitors; however, their ether-linked lipids
provide stability in extreme environments. These organisms are archaea, not bacteria.
