Is wuchereria a nematode?

CHARACTERISTICS: Wuchereria bancrofti is a filarial nematode that, as an adult, is a thread-like worm(1,2,3). The female nematodes are 10 cm long and 0.2 mm wide, while the males are only about 4 cm long(1,3).

What type of worm is Wuchereria?

Wuchereria bancrofti is a filarial (arthropod-borne) nematode (roundworm) that is the major cause of lymphatic filariasis. It is one of the three parasitic worms, together with Brugia malayi and B.

Are filarial nematodes?

The filariae are thread-like parasitic nematodes (roundworms) that are transmitted by arthropod vectors. The adult worms inhabit specific tissues where they mate and produce microfilariae, the characteristic tiny, thread-like larvae.

Which nematode causes filariasis?

Lymphatic filariasis is caused by the worms Wuchereria bancrofti, Brugia malayi, and Brugia timori. These worms occupy the lymphatic system, including the lymph nodes; in chronic cases, these worms lead to the syndrome of elephantiasis.

Where is Wuchereria found?

Wuchereria bancrofti is a filarial worm found in the lymph nodes of humans causing a lymphatic filariasis called Bancroft's filariasis. Humans are the only known natural definitive host.

Is wuchereria a free living animal?

While many bacteria are free-living, many others form symbiotic relationships of commensalistic, mutualistic, or parasitic nature. The role of insects in the transmission of protozoans such as Plasmodium, Leishmania, and Trypanosoma and nematodes such as Wuchereria, Onchocerca, and Brugia has already been discussed.

Is microfilaria a parasite?

The microfilaria (plural microfilariae, sometimes abbreviated mf) is an early stage in the life cycle of certain parasitic nematodes in the family Onchocercidae. In these species, the adults live in a tissue or the circulatory system of vertebrates (the "definitive hosts").

Is hookworm a nematode?

Human hookworm disease is a common helminth infection worldwide that is predominantly caused by the nematode parasites Necator americanus and Ancylostoma duodenale; organisms that play a lesser role include Ancylostoma ceylanicum, Ancylostoma braziliense, and Ancylostoma caninum.

What are tissue nematodes?

Tissue roundworms include Trichinella spiralis, Dracunculus medinensis and Toxocara canis, which remain within tissues and neither release eggs nor microfilariae into the blood; they are not transmitted via arthropods. Nematodes which are transmitted to humans via arthropods include lymphatic filaria such as W.

What phylum are hookworms a part of?

hookworm, any of several parasitic worms of the genera Necator and Ancylostoma belonging to the class Nematoda (phylum Aschelminthes) that infest the intestines of humans, dogs, and cats.

Is elephantiasis a protozoan disease?

Additional causes of elephantiasis include a protozoan disease called leishmaniasis, tuberculosis, leprosy, and a repeated streptococcal infection. Elephantiasis may also occur secondary to trauma, surgery or radiation if lymphedema is not treated..

Which disease is caused by nematode?

Nematode infections in humans include ascariasis, trichuriasis, hookworm, enterobiasis, strongyloidiasis, filariasis, trichinosis, dirofilariasis, and angiostrongyliasis (rat lungworm disease), among others.

Is Ascaris a nematode?

Ascaris species are very large (adult females: 20 to 35 cm; adult males: 15 to 30 cm) nematodes (roundworms) that parasitize the human intestine. A. lumbricoides is the primary species involved in human infections globally, but Ascaris derived from pigs (often referred to as A. suum) may also infect humans.

Are roundworms prokaryotic or eukaryotic?

elegans) The microscopic roundworm, C. elegans, is an excellent model for understanding how cells divide, develop, and take on specialized tasks in higher (eukaryotic) organisms.

Why Ascaris is classified in the phylum Nematoda?

So, we've established that Ascaris is a genus of helminth. They belong to the Kingdom Animalia (just like us), and the Phylum Nematoda (from the Greek 'nematos' meaning 'thread'). ... Nematodes are pseudocoelomates, meaning they have a 'fake' coelom. A coelom is a body cavity that surrounds the digestive track.
