The correct answers are 1, 2, 3, and 5. Sputum, blood, and infected lymph node aspirate should be examined for the presence of Y pestis. The Y pestis organism may appear as a Gram-negative bacillus in any of these sources.
Y pestis may be seen in smears of the sputum, peripheral blood, or lymph node aspirate. The organism is a Gram-negative bacillus or coccobacillus[4] demonstrating bipolar staining with the Wright, Giemsa, or Wayson stains, and may exhibit a characteristic "safety pin" appearance. Positive cultures from these sources may appear within 24-48 hours, but may take as long as 6 days.
