Correct answer: A. Trichrome Methylene blue

  • A. Trichrome Methylene blue
  • B. Carbol Fuschin
  • C. Acid Fast Stain
  • D. Calcoflour White

Explanation

An abattoir worker with a papule progressing to an ulcer suggests cutaneous anthrax, caused by Bacillus anthracis. Polychrome methylene blue, also called the M’Fadyean stain, demonstrates the organism and its capsule; acid-fast and fungal stains are not appropriate.
