Coloured SEM of Giardia lamblia in human intestine

Giardia lamblia. Coloured Scanning Electron Micro- graph (SEM) of the parasite Giardia lamblia in the human small intestine. A number of these single- celled protozoans are seen (green); pear-shaped, they have flagellae for motility. They cause the disease giardiasis (or lambliasis), an infection of the small intestine most common in tropical areas. Giardia lamblia attaches by means of sucking discs to microvilli in the human intestine. Abdominal cramps, swelling, diarrhoea and nausea may occur. The organism is spread by direct contact or through contaminated food and water. Magnification: x3, 800 at 6x7cm. x4, 860 at 4x5ins

Flagellate Intestine Protozoa Protozoan

EDITORS COMMENTS
This print showcases a coloured scanning electron micrograph (SEM) of Giardia lamblia, a parasitic organism found in the human small intestine. The image reveals numerous green, pear-shaped single-celled protozoans with flagellae for motility. These microscopic creatures are responsible for causing giardiasis, also known as lambliasis, which is an infection commonly found in tropical regions. Giardia lamblia attaches itself to microvilli within the human intestine using sucking discs. This interaction can lead to various symptoms such as abdominal cramps, swelling, diarrhoea, and nausea. The transmission of this parasite occurs through direct contact or consumption of contaminated food and water. The magnification level used to capture this intricate detail is truly remarkable: x3,800 at 6x7cm or x4,860 at 4x5ins. This highly detailed SEM image allows us to appreciate the complexity of these tiny organisms that play a significant role in human health. Nature enthusiasts and those interested in zoology will find this print fascinating due to its depiction of an often overlooked aspect of wildlife - the diverse world of parasites that exist within our own bodies. Science Photo Library has once again provided us with an awe-inspiring glimpse into the wonders of nature's microscopic realm.
