What anthrax causesd elevated white blood cell count and widened mediastinum?

The form of anthrax that causes elevated white blood cell counts and a widened mediastinum is inhalation anthrax. This severe form occurs when spores of the bacterium Bacillus anthracis are inhaled, leading to respiratory symptoms and systemic infection. The widened mediastinum is often due to mediastinal lymphadenopathy or pleural effusion, while the elevated white blood cell count reflects the body's immune response to the infection. Inhalation anthrax is a medical emergency and requires prompt treatment.
