Giardia protozoan, SEM C016 / 9398
Giardia protozoan. Coloured scanning electron micrograph (SEM) of a Giardia sp. trophozoite protozoan (yellow) attached to the lining of a human intestine. Giardia are single-celled parasites of the intestinal tract. They are most common in tropical regions and have flagella (hair-like structures), which are used for locomotion. They are the causative agent of giardiasis, an intestinal disease that causes abdominal pain, diarrhoea and nausea. It is spread through contaminated food and water. Treatment is with antibiotics or antiprotozoal drugs, such as metronidazole

EDITORS COMMENTS
This print showcases the Giardia protozoan, a single-celled parasite that resides in the human intestine. The coloured scanning electron micrograph (SEM) reveals a Giardia sp. trophozoite protozoan attached to the intestinal lining, depicted in vibrant yellow against a striking black background. Giardia is commonly found in tropical regions and possesses flagella, hair-like structures that aid in its locomotion. Unfortunately, these parasites are responsible for causing giardiasis, an intestinal disease characterized by symptoms such as abdominal pain, diarrhea, and nausea. The transmission of this illness occurs through contaminated food and water sources. In order to combat giardiasis effectively, antibiotics or antiprotozoal drugs like metronidazole are prescribed for treatment. This SEM image provides valuable insights into the life cycle of Giardia and highlights its pathogenic nature within the gastrointestinal tract. The intricate details captured by this photograph emphasize the importance of understanding parasitic infections on both a medical and biological level. By studying microorganisms like Giardia using advanced imaging techniques such as scanning electron microscopy (SEM), researchers can gain crucial knowledge about their structure and behavior. AMI IMAGES/SCIENCE PHOTO LIBRARY has expertly captured this microscopic world with precision and artistry, allowing us to appreciate the complexity of these tiny organisms that have significant impacts on human health.
