Etymology

The word legionella comes from Legion because the bacteria were first found after a sickness outbreak at an American Legion convention in 1976. The ending -ella comes from Latin and means 'small', so the name suggests a 'small legion' and helps you remember that legionella is the bacterium behind 'Legionnaires' disease' and can spread in water systems.
