For confirming anthrax infection, which method is used for confirmation?

• A. Bacterial culture and identification
• B. Virus isolation
• C. Serology only
• D. PCR only

Answer: (A)

Definitive confirmation of anthrax infection comes from isolating Bacillus anthracis from a clinical specimen and proving its identity. Culturing the organism on appropriate media and demonstrating the characteristic features—Gram-positive rods that are non-motile, form non-hemolytic colonies with the distinctive appearance, and possess the capsule and virulence genes—provides definitive evidence. PCR can offer rapid support by detecting specific B. anthracis DNA, but Culture and identification remain the standard for final confirmation. Serology alone is unreliable for acute confirmation, and virus isolation isn’t applicable since this is a bacterial, not a viral, disease.
