Under a very very high magnification of 10000X, this 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 11146 for a colorized 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. For a better view of these bacterial appendages, see the colorized version.Created: 2009

L. pneumophila are known to most frequently exhibit this configuration when grown in broth, however, they can also elongate when plate-grown cells age, as it was in this case, especially when they’ve been refrigerated.Created: 2009

Under a moderately-high magnification of 8000X, this scanning electron micrograph (SEM) depicted a grouping of Gram-negative Legionella pneumophila bacteria. Please see PHIL 11092 through 11160 for additional SEMs of these organisms, specifically PHIL 11128 for a colorized version of this image. It appears that a few are still joined to one another just prior to the completion of their reproductive process known as cell division. In some of these views you'll note the presence of flagellar appendages.You’ll note that a number of these bacteria seem to display an elongated-rod morphology. L. pneumophila are known to most frequently exhibit this configuration when grown in broth, however, they can also elongate when plate-grown cells age, as it was in this case, especially when they’ve been refrigerated. The usual L. pneumophila morphology consists of stout, fat bacilli, which is the case for the vast majority of the organisms depicted here.Created: 2009
