Latest Flatworm Stories
Two groups of lowly marine worms are related to complex species including vertebrates (such as humans) and starfish.
A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report.
In the most computationally intensive phylogenetic analysis to date, an international research team led by Brown University has found the first evolutionary branching for bilateral animals.
Amputations trigger a molecular response that determines if a head or tail will be regrown in planaria, a flatworm commonly studied for its regenerative capabilities.
Two international research teams have determined the complete genetic sequences of two species of parasitic flatworms that cause schistosomiasis, a debilitating condition also known as snail fever.
University of Minnesota Medical School researchers have discovered an important new insight into how a commonly prescribed drug may work to treat those infected by a parasitic flatworm.
A U.S. study shows a key genetic pathway for cell growth and division is similar in both humans and flatworms, or planarians. Planarians, normally living in freshwater, are known for their ability to regenerate. A planarian cut into 200 pieces can generate 200 new individuals.
Key genetic pathways for cell growth and division are similar in both humans and the invertebrate master of regeneration -- the planarian.
The nightcrawler (Lumbricus terrestris), also known as the lob worm or the common earthworm in Britain and the dew worm in Canada, is a species of earthworm that is classified within the Annelida phylum. It is native to Europe, but has been introduced into other areas around the world. Although the species is not as abundant as other worms in its range, it is a widely known species in gardens of temperate habitats, where it moves about on the surface of the soil. The nightcrawler can reach...
The rodent tapeworm (Hymenolepis microstoma) is a parasitic worm that is classified within the Platyhelminthes phylum. This species affects rodents across the world, causing hymenolepiasis, but it does not often affect humans. Most of the available information regarding tapeworms is derived from the studies conducted on this worm and the other members of its genus, Hymenolepis. These worms have been present in laboratories since the 1950's and can either be raised and kept in a culture or be...
The dwarf tapeworm (Hymenolepis nana) is a species of tapeworm that is classified in the Platyhelminthes phylum. It once held three other scientific names including Vampirolepis nana and Taenia nana. It is found throughout the world but occurs most often in temperate regions. As its common name implies, the dwarf tapeworm is small, reaching an average body length of 1.5 inches. The head, or scolex, holds a retractable beak like organ that has twenty to thirty hooks and four string suckers,...
The beef tapeworm (Taenia saginata or Taeniarhynchus saginata) is a species of tapeworm that is classified within the Platyhelminthes phylum. It can affect both cattle and humans, and causes the disease taeniasis in humans. It can be found in many areas that have a beef market including Africa, the Philippines, Latin America, and Eastern Europe, although it is not abundant in this area. It does occur in the United States, but it is not common due to high sanitation standards. The beef...
