Magnified 23,493x, this scanning electron micrograph (SEM) depicted a highly enlarged view of a Ralstonia mannitolilytica bacterium, which was harvested from a pure culture.Created: 2006

Magnified 23,502x, this scanning electron micrograph (SEM) depicted a highly enlarged view of a Ralstonia mannitolilytica bacterium, which was harvested from a pure culture. Note that in this particular instance, the bacterium is in the process of undergoing replication, which when completed, will give rise to three separate bacteria.Created: 2006

This photomicrograph depicted the results of using the Indirect Fluorescent Antibody (IFA) technique to confirm the presence of Legionella pneumophila bacteria in this human lung secretion sample from a suspected victim of Legionnaires’ disease.Created: 1978

Under a moderately-high magnification of 8000X, this colorized scanning electron micrograph (SEM) depicted a large grouping of Gram-negative Legionella pneumophila bacteria. Please see PHIL 11092 through 11152 for additional SEMs of these organisms, specifically PHIL 11151 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.Created: 2009

Please see PHIL 11092 through 11152 for additional SEMs of these organisms, specifically PHIL 11138 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.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.Created: 2009
