Listeria bacteria, SEM
Listeria sp. bacteria, coloured scanning electron micrograph (SEM). Listeria are Gram-positive rod-shaped bacteria. The species L. monocytogenes is a human pathogen, causing the disease listeriosis. Symptoms of listeriosis include fever, meningitis and encephalitis (swelling of the brain). It is caught from contaminated food and is most common in newborns, the elderly and immunocompromised patients

EDITORS COMMENTS
This print showcases the intricate beauty of Listeria bacteria, as captured under a scanning electron microscope. The vibrant colors bring to life these Gram-positive rod-shaped microorganisms, which belong to the Listeria genus. While visually stunning, it is important to note that one species within this group, L. monocytogenes, poses a significant threat to human health. Listeriosis is the disease caused by L. monocytogenes and can lead to various symptoms such as fever, meningitis, and encephalitis – characterized by swelling of the brain. This pathogenic bacterium is primarily transmitted through contaminated food and tends to affect vulnerable populations including newborns, elderly individuals, and those with weakened immune systems. The image serves as a reminder of the hidden dangers lurking in our environment and highlights the importance of proper food safety practices. By understanding these microscopic organisms better through scientific research in bacteriology and microbiology fields, we can work towards preventing outbreaks of listeriosis and other foodborne illnesses.
