This thin section transmission electron micrograph (TEM) depicted a Gram-negative Legionella pneumophila bacterium, which was cultured in an embryonated hen's egg; Magnified approximately 119,500x.
At least 46 Legionella spp., and 70 serogroups have been identified. L. pneumophila, an ubiquitous aquatic bacterial organism, which thrives in warm environments, primarily at temperatures ranging from 32 degrees to 45 degrees C, and causes over 90 percent of Legionnaires' disease, (LD), in the United States. Legionnaires' disease, (LD), is the more severe form of legionellosis and is characterized by pneumonia, commencing 2-10 days after exposure. Pontiac fever is an acute-onset, flu-like, non-pneumonic illness, occuring within a few hours to two days of exposure.
