Image of Legionella pneumophila

Description:

Under a high magnification of 10000X, this colorized scanning electron micrograph (SEM) depicted a number of Gram-negative Legionella pneumophila bacteria. Please see PHIL 11092 through 11152 for additional SEMs of these organisms, specifically PHIL 11129 for a black and white version of this image. Of particular importance, is the presence of polar flagella, and pili, or long streamers, which due to their fragile nature, in some of these views seem to be dissociated from any of the bacteria.
