What organism is responsible for Legionellosis?

  1. Legionella pneumophila

  2. Aspergillus species

  3. Escherichia coli

  4. Mycobacterium tuberculosis

The correct answer is: Legionella pneumophila

Legionellosis, also known as Legionnaires' disease, is a severe form of pneumonia caused by the Legionella pneumophila bacterium. This bacterium is not found in the other answer options, which are fungi (Aspergillus species), a different bacterium (Escherichia coli), and a tuberculosis-causing bacterium (Mycobacterium tuberculosis). Legionella pneumophila is commonly found in water sources, such as hot tubs, cooling towers, and building water systems, and can be inhaled when the water is aerosolized. It is important to correctly identify the organism responsible for a disease in order to effectively treat and prevent it.
