Scolex (head) of a beef tapeworm, Taenia saginata
Tapeworm head. Light micrograph of the scolex (head) of the adult beef tapeworm Taenia saginata. At upper left, two rounded structures are suckers by which the tapeworm attaches itself to the intestinal wall of its host. The head narrows into a segmented neck. Taenia saginata is the commonest tapeworm parasite in humans, infecting millions of people worldwide. Tapeworms have no digestive systems of their own but absorb directly through their skin the food ingested and broken down by the host. The adult tapeworms may grow 10 metres in length. Diarrhoea, weight loss and abdominal discomfort may result. Treatment is with anthel- minthic drugs. Magnification: x32 at 6x6cm size

Beef Flat Worm Platyhelminthes Scolex Tape Worm Light Micrograph Taenia Saginata
EDITORS COMMENTS
This print showcases the intricate details of the scolex, or head, of a beef tapeworm known as Taenia saginata. The light micrograph reveals two rounded structures at the upper left corner, which are the suckers that enable this parasitic creature to firmly attach itself to the intestinal wall of its host. As we follow along, we witness how the head narrows into a segmented neck. Taenia saginata is one of the most prevalent tapeworm parasites in humans and has infected millions worldwide. These fascinating organisms lack their own digestive systems and instead absorb nutrients directly through their skin from the food ingested and broken down by their hosts. Astonishingly, adult tapeworms can reach lengths of up to 10 meters. However, living with these unwelcome guests comes with consequences such as diarrhea, weight loss, and abdominal discomfort for those affected. Fortunately, treatment options involving anthelminthic drugs exist to combat these infections. Through this extraordinary image captured at a magnification of x32 on a 6x6cm scale by Science Photo Library, we gain insight into both nature's wonders and potential health concerns associated with these remarkable creatures belonging to the phylum Platyhelminthes.
