Characteristics The family Legionellaceae consists of faintly staining, Gram negative, pleomorphic … human pathogenic bacterium in this group and is the causative agent of many While L. pneumophila is categorized as a Gram-negative organism, it stains poorly due to its unique lipopolysaccharide content in the outer leaflet of the outer cell membrane.
