Legionella

 [le″jun-el´ah]
a genus of gram-negative, aerobic rod-shaped bacteria, the cause of legionellosis. Species include L. micda´dei, the etiologic agent of Pittsburgh pneumonia, and L. pneumo´phila, the etiologic agent of legionnaires' disease and pontiac fever.

Legionella

(lē'jŭn-el'lă),
A genus of aerobic, motile, nonacid-fast, nonencapsulated, gram-negative bacilli (family Legionellaceae) that have a nonfermentative metabolism and require l-cysteine HCl and iron salts for growth; they dwell in water, spread in air, and are pathogenic for humans. Over 40 species have been identified; the type species is Legionella pneumophila.

Le·gion·el·la

(lējŏ-nelă)
A genus of aerobic, motile, non-acid-fast, nonencapsulated, gram-negative bacilli; they dwell in water and are borne by air; pathogenic for humans. The type species is L. pneumophila.
