nematode worms examples
Nematodes consists of bebearpa order as follows:
Roundworm (Ascaris lumbrricoides)

Live in the human gut, is cosmopolitan (found in all places). The body wall is composed of a cuticle, epidermis and longitudinal muscle layers where there excretion channel lateral, dorsal and ventral nerve cord are connected by anterior nerve ring, rounded body shape long section tapered ends. body length of female worms ± 0.5 cm, while the male worms 1.5 to 2.4 cm, mouth terlatak tip of the anterior and is equipped with three lips, the body relatively more straight female worms, while the posterior end of the male worms had that roll, food in the form of food juices, the digestive tract is composed of the above: the mouth, pharynx, intestine and anus. Roundworm (Ascaris lumbrriciodes) causes the disease known as ascariasis. Example: Ascaris Prasit in the human intestine, the intestinal parasite Ascaris megalocaphala horse, suilae parasite Ascaris in the intestine of pigs.
The life cycle of roundworm, the fertilized egg free kealam out with feces. If the eggs ingested with food or drink, then in the intestines of these eggs will hatch into larvae, then grow into adult worms.
Hookworm (Anylostoma)

Live parasites in intestines of humans and many dijumapai in mining regions, especially in hot climates. These worms suck blood that can lead to death, the blood sucking, this worm mengeluakan anti-coagulant agents (hirudin) which prevents blood clots. Body length of approximately 1-1,5cm in humans. Examples hookworm Ancylostoma duodenale is that there are areas of tropical Africa and Asia and Necator americanus are found in America.
Life cycle of hookworms, the adult worm is ectoparasites in the human intestine. Worm eggs can come out with human feces, the fertilized egg will hatch and the larvae within a day aimlessly filariform. These larvae can penetrate the skin, with the flow of blood to the heart and lungs, after that go back to the intestines and grow into adults.
Pinworms (Enterobius vermicularis)

Living in the human colon, the body length between 9-15mm. at the time of laying eggs, worms toward the anus to obtain the oxygen needed for growth. Movement of these worms can cause itching in the anus. The body affected by this worm infection may contain worms 5000. Example: Oxyuris equi anal horse or donkey.
Filarial worms (Wuchereria bancrofti)

Filarial worms have arthropod intermediate host animals, for example mosquitoes, and the host remains the man in the lymph vessels. If the dead filarial worms clog the lymph vessels, it causes swelling or disease elephantiasis (elephantiasis). Microfilariae can enter the human body through the bite of the Culex mosquito.
Muscle worms (Trichinella spiralis)

These worms cause the disease trichinosis in humans, pigs or mice. The worms enter the human body through the pork undercooked. In the human intestine, the larvae multiply into young worms then become adult worms. To prevent infection by this worm, the meat should be cooked thoroughly to kill young worms.
Heterodera radicola

Live parasites on the roots of the plant, causing swelling in the plant.

Thus post today regarding the classification of biological nematode, may be useful for us all.
