The pulmonary form of anthrax is known as which of the following?

• A. Valley fever
• B. Walking pneumonia
• C. Farmers' lung
• D. Woolsorters disease

Answer: (B)

The pulmonary form of anthrax is known as Woolsorters’ disease. This name comes from historical cases among workers who handled contaminated wool, hides, or animal products; inhaling the Bacillus anthracis spores leads to a severe, rapidly progressive lung infection. The term specifically points to the inhalational form, which is different from other pneumonia-like illnesses.

Why this fits best: inhalational (pulmonary) anthrax has long been labeled Woolsorters’ disease, highlighting its route of entry and occupational association. The other options refer to completely different conditions: valley fever is coccidioidomycosis, walking pneumonia is typically Mycoplasma pneumoniae infection, and farmers’ lung is a hypersensitivity pneumonitis from moldy hay. None of those are anthrax, making the Woolsorters’ disease designation the correct match for the pulmonary form.
