Pneumonic Plague - Laboratory Testing
- Specimens should be collected before initiating any therapy.
- Sputum, blood, and lymph node aspirate should be submitted
for Gram stain and culture.
- Microscopic Findings:
- Gram-negative rods
- Wright, Giemsa, or Wayson stains may show bipolar (safety
pin) staining.
- Sera for acute and convalescent antibody detection should
be obtained to assist public health authorities in their management
of the case, but are not usually helpful in diagnosis due
to the length of time for testing.
