Legionella is a gram-negative aerobic bacterium of which more than fifty species have been identified: the most dangerous is the "legionella pneumophila".
Approximately 90% of "legionellosis" cases are attributable to this type of legionella.
It is an infection that mostly affects the respiratory system and can manifest itself in the form of headache, high fever, muscle pain, chest pain, disorientation and confusion.
35°C -45°C : critical range of development and proliferation
>55°: beginning of the progressive death of the bacterium
70°C -80°C :rapid death rate of legionella
