Legionella bacteria

Legionella bacteria. Coloured transmission electron micrograph (TEM) of four Legionella pneumophila bacteria. The bacteria (pale green) cause Legionnaires disease. They are rod-shaped Gram-negative bacilli with a single motile flagellum (purple). It was named after its first recognised victims, 29 American Legion members who died at a hotel in 1976. The bacteria lives in water tanks and air conditioning systems. The disease, also called legionellosis, causes fatal pneumonic lung damage in the elderly and unfit. It can be treated with antibiotic drugs such as erythromycin. Magnification unknown

EDITORS COMMENTS
This print showcases the Legionella bacteria, specifically Legionella pneumophila. Coloured in a pale green hue under transmission electron microscopy (TEM), these rod-shaped Gram-negative bacilli are depicted with their distinguishing motile flagellum in purple. The name "Legionella" was derived from its initial victims, 29 members of the American Legion who tragically lost their lives at a hotel in 1976. These bacteria thrive within water tanks and air conditioning systems, posing a significant risk to human health. They are responsible for causing Legionnaires disease or legionellosis, which manifests as fatal pneumonic lung damage primarily affecting the elderly and individuals with weakened immune systems. Fortunately, medical science has developed effective treatments for this severe respiratory infection. Antibiotic drugs like erythromycin have proven successful against combating this bacterial menace. The magnification used to capture this image remains unknown; nonetheless, it offers an extraordinary glimpse into the intricate world of microbiology. This photograph serves as a reminder of the hidden dangers lurking within our environment and emphasizes the importance of proper maintenance and hygiene practices to prevent outbreaks caused by these microorganisms. Science Photo Library presents this remarkable visual representation that not only educates but also sparks curiosity about the microscopic organisms that coexist alongside us every day.
