Legionella: Facultative intracellular, gram negative rod
Pili: They are all involved in adherence and intracellular replication of L. pneumophila
Flagella: Within the host cell vacuole, legionella are nonmotile, whereas in the later stages of infection and cell lysis, legionella are flagellated and highly motile. Motility enables Legionella to escape from a spent host and facilitates its attempt to find a new host by dispersion into the environment.

Enzymes: Protects the bacteria from macropage superoxide and hydrogen peroxide oxidative burst.
Copper, zinc superoxide dismutase (or Cu,Zn SOD)
Catalase
Catalase
Peroxidase
Secretes: RNAase, phospholipase A, phospholipase C.
Toxins: Cytotoxin kills hamster ovary cells.
Reservoir: Air conditioning system.
It is a ubiquitous microorganism inhabiting natural and man-made freshwater biotopes.
