- Nematodes are the most numerous multicellular animals on earth. A handful of soil will contain thousands of the microscopic worms, many of them parasites of insects, plants or animals.Free-living species are abundant, including nematodes that feed on bacteria, fungi, and other nematodes, yet the vast majority of species encountered are poorly understood biologically. handful of soil will contain thousands of the microscopic worms, many of them parasites of insects, plants or animals.

Dracunculus medinensis Dracunculus medinensis or Guinea worm is a nematode that causes dracunculiasis, also known as guinea worm disease.The disease is caused by the female which, at up to 800 mm (31 in) in length, is among the longest nematodes infecting humans. In contrast, the longest recorded male Guinea worm is only 40 mm (1.6 in).racunculus medinensis or Guinea worm is a nematode that causes dracunculiasis, also known as guinea worm disease.

What is a Climate Zone? A climate zone is a region of the world where the climate can be defined using a few key parameters. There are a number of different ways to classify the world's climate zones, and a wide assortment of uses for this information.

- C. elegans are nematodes used as model organisms in many research fields including genetics, toxicology, human development, and neurodegeneration. WormLab gives researchers a wide variety of accurate and precise analyses about C. elegans locomotion, including position, speed, direction, and wavelength.

- By Dr Ananya Mandal, MD. Helminths are parasitic worms that feed on a living host to gain nourishment and protection, while causing poor nutrient absorption, weakness and disease in the host.These worms and larvae live in the small bowel and are referred to as intestinal parasites.ome of the features of the different groups of the helminths include: 1  The trematodes or flatworms are flat, leaf-shaped and unsegmented. 2  Nematodes are cylindrical and have lips, teeth and dentary plates. 3  The cestodes or tapeworm is segmented and hermaphroditic.

- Caenorhabditis elegans (C. elegans) is a proven model in biological research. The nematode's cell lineage has been mapped and its genome fully sequenced. These attributes, combined with its small size and short lifecycle, its transparency and the generation of multiple progeny, have made the worm an attractive model for studies, including those on developmental and reproductive behavior.

- Nematodes are commonly encountered internal parasites in aquatic turtles. They are similar to roundworms that infect mammals and occur when a turtle ingests the parasitic eggs that have been passed from the system of infected animals.quatic turtles are plagued by a number of internal and external parasites. As in the case with all reptiles, these parasites can cause severe health issues and possible death, unless treated. In almost all cases, aquatic turtles contract parasites through unsanitary environmental conditions.

Nematode The nematodes (/ˈnɛmətoʊdz/) or roundworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a broad range of environments. Nematode species can be difficult to distinguish, and although over 25,000 have been described, of which more than half are parasitic, the total number of nematode species has been estimated to be about 1 million.

Caenorhabditis elegans Caenorhabditis elegans (/ ˌ s iː n oʊ r æ b ˈ d aɪ t ə s ˈ ɛ l ə ɡ æ n z /) is a free-living (not parasitic), transparent nematode (roundworm), about 1 mm in length, that lives in temperate soil environments. The name is a blend of the Greek caeno-(recent), rhabditis (rod-like) and Latin elegans (elegant).

Trichinella Trichinella is the genus of parasitic roundworms of the phylum Nematoda that cause trichinosis (also known as trichinellosis).Members of this genus are often called trichinella or trichina worms.A characteristic of Nematoda is the one-way digestive tract, with a pseudocoelom (body cavity made up of only an ectoderm and endoderm). The genus was first recognised in a larval form in 1835.embers of this genus are often called trichinella or trichina worms.

Trichinella spiralis From Wikipedia, the free encyclopedia. Trichinella spiralis is an ovoviviparous nematode parasite, occurring in rodents, pigs, horses, bears, and humans, and is responsible for the disease trichinosis. It is sometimes referred to as the pork worm due to it being found commonly in undercooked pork products. 1 Description.

Threadworms See also: Threadworms written for patients. This is a very common nematode infection which occurs throughout the world. It is also known as pinworm or enterobiasis, as it is caused by infection with Enterobius vermicularis. The male threadworm is about 4 mm long and is rarely seen. The female is bigger at 1 cm long and a little under 1 mm in diameter. It is white and pointed at each end.

Pinworm Infection A pinworm infection is a type of human intestinal worm infection. Pinworms are tiny, narrow worms that are white and less than half an inch long. A pinworm infection, also known as enterobiasis or oxyuriasis, is the most common type of worm infection in humans in the United States.

- Nematodes are roundworms of the Phylum Nematoda order. Most nematodes live in the soil in very large numbers and are best known as plant parasites that live in or on plant roots. However, studies are now revealing lesser-known, beneficial types of nematodes that help in pest control and the breakdown of organic matter.

Roundworms Introduction. Roundworms, or nematodes, are parasites that can infect people. They usually live in the intestines. There are different kinds of worms that can cause infection, and they can range in length from 1 millimeter to 1 meter.

Nematodes - the good, the bad and the ugly. Many species of nematodes are ‘free-living’, living in soil, sea and freshwater. These feed on bacteria, fungi, protozoans and even other nematodes, and play a very important role in nutrient cycling and release of nutrients for plant growth.ome species of nematodes live in the stomach of animals and prevent them from absorbing sufficient nutrients to grow properly. Farmers commonly treat their livestock with chemicals called ‘drenches’ or ‘anthelmintics’ to kill such nematode infestations.

Trichinella spiralis Trichinella spiralis is the smallest known nematode parasite of humans. The males measure about 1.4 mm to 1.6 mm in length and the females are twice the size of the males. The body of the worm is more slender at the anterior then at the posterior end.

- Some free-living nematodes are found in hot springs, the soil, or even vinegar while others are important endoparasites of humans, animals and plants. The roundworms have tapered, cylindrical bodies and are bilaterally symmetrical pseudocoelomates with a complete digestive system. Trichina worm (Trichinella spiralis) Trichinosis is caused by the infection of trichina worms. Humans, swine (most common host in the US), bears, rats and many other mammals may serve as the host.

Real Viruses, Worms, Spyware, and Moreâ¦ Worms are self-propagating computer viruses. Webopedia defines a worm as: “A program or algorithm that replicates itself over a computer network and usually performs malicious actions, such as using up the computer’s resources and possibly shutting the system down.” Their impact is similar to computer viruses.

Ascaris lumbricoides Ascaris lumbricoides. Ascaris lumbricoides, the giant roundworm, are the largest nematode that is a parasite to humans. They grow up to 30 cm in length. They live in the small intestine of humans. These worms reproduce inside the small intestine and the eggs pass out in the stool. After two weeks the eggs become infectious.

- Nematoda (nematodes, eelworms, threadworms, roundworms; phylum Aschelminthes) Class of aschelminth worms (a phylum in some classifications) which vary greatly in size, from about 1 mm to 5 cm. The cuticle has flanges, and may also have ridges or spines.ematode. Nematodes, also called roundworms, are members of the animal phylum Nematoda. These worms have a complete digestive system and are more complex than the flatworms (phylum Platyhelminthes) but lack a circulatory system and other advanced features found in the annelids (segmented worms).

Worms A Worm is an elongated soft-bodied invertebrate animal. The best-known is the earthworm, a member of phylum Annelida, however, there are hundreds of thousands of different species that live in a wide variety of habitats other than soil. Most worms live in our gardens and in other soiled areas such as fields and farms. Worms do not have arms, legs or bones, instead, they have a soft, often segmented body which is covered a tiny hairs or bristles that help them move along. Worms breathe through their skin and so it must be kept moist all the time to enable them to absorb the oxygen from the air.
