Naegleria fowleri protozoa, TEM
Naegleria fowleri protozoan. Coloured transmission electron micrograph (TEM) of a section through a Naegleria fowleri protozoan. The nucleus (purple) contains a large nucleolus (orange), in which ribonucleic acid is synthesised. This organism is an opportunistic pathogen of humans, causing meningoencephalitis (inflammation of the brain and its surrounding membranes) when inhaled, often by children swimming in fresh water. Headaches, vomiting, sensory disturbance and a fatal coma may occur if the victim is not treated, often with a combination of antibiotics and anti-fungal drugs. Magnification: x3300 at 6x7cm size

EDITORS COMMENTS
This print showcases a coloured transmission electron micrograph (TEM) of the Naegleria fowleri protozoa. The intricate details of this organism are brought to life, revealing its complex structure and vibrant colors. At the center, we see the nucleus in a striking shade of purple, housing a large nucleolus that glows in an eye-catching orange hue. It is within this nucleolus that ribonucleic acid is synthesized. However, behind its mesmerizing appearance lies a dangerous truth. This opportunistic pathogen poses a threat to humans, particularly when inhaled by children swimming in fresh water. Once inside the body, it can cause meningoencephalitis - an inflammation of the brain and its surrounding membranes. The symptoms associated with this infection are severe and potentially fatal if left untreated. Headaches, vomiting, sensory disturbances become prevalent as the disease progresses towards a coma-like state. To combat this menacing pathogen, treatment often involves a combination of antibiotics and anti-fungal drugs. With magnification at x3300 for 6x7cm size prints like these offer us glimpses into microscopic worlds that would otherwise remain hidden from our view. They serve as reminders of both the beauty and dangers present within nature's smallest creations.
