Legionellales

Legionella is a genus of Gram-negative bacteria that can be seen using a silver stain or grown in a special media that contains cysteine, an amino acid. Most Legionella species are intracellular pathogens whose primary hosts are amoebae, however many Legionella are accidental pathogens of humans. Legionella bacteria are known to cause legionellosis (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever. These bacteria are common in many places, like soil and water. Legionella are aerobic and motile.

The Legionellales are an order of Pseudomonadota ("Proteobacteria"). Like all Pseudomonadota, they are Gram-negative. They comprise two families, typified by Legionella and Coxiella, both of which include notable pathogens. For example, Q fever is caused by Coxiella burnetii and Legionella pneumophila causes Legionnaires' disease and Pontiac fever.

legionellosis that involves a milder respiratory illness without pneumonia. Symptoms include fever, headache and muscle aches which last for 2 to 5 days

The Coxiellaceae are a family in the order Legionellales.

Rickettsiella is a genus of bacteria in the family Coxiellaceae. It should not be confused with Rickettsia. It is currently considered of the Gammaproteobacteria. However, its placement under Coxiellaceae instead of Legionellaceae has been challenged.
