guinea worm, (Dracunculus medinensis), also called medina worm or dragon worm, member of the phylum Nematoda. The guinea worm, a parasite of humans, is found in tropical regions of Asia and Africa and in the West Indies and tropical South America.

What type of pathogen is Dracunculus medinensis?

Dracunculiasis (guinea worm disease) is caused by the nematode (roundworm) Dracunculus medinensis.

What is the common name of dracunculiasis?

Dracunculiasis, also known as Guinea worm disease (GWD), is an infection caused by the parasite Dracunculus medinensis.

What is the morphology of Dracunculus medinensis?

Parasite morphology: Guinea-worms develop through four larval stages prior to the formation of large adult worms; eggs are not produced.

What is the infective stage of Dracunculus medinensis?

Dracunculus medinensis (Dracunculiasis)

Freshwater copepods ingest the larvae, which then mature to the infective stage (L3 larvae) and are transmitted back to humans when copepods are accidentally swallowed in drinking water.

What is the vector for Dracunculus?

The most important implicated potential vectors of Dracunculus medinensis evaluated in the area are Mesocyclops kieferi –> M. aspericornis –> Thermocyclops incisus –> T.

Is Dracunculus medinensis a filarial worm?

Dracunculus medinensis, the guinea worm, is not a true filarial worm, but is often grouped with the filariae. It is one of the oldest known parasitic diseases of man.

What is the secondary parasite of Dracunculus?

Hosts: Dracunculus medinensis is a parasite of humans, dog, horse, cow, wolf, leopard, monkey, and baboon. Juvenile stages live in fresh water and infect copepods (e.g. Cyclops – water fleas), the secondary host.

What is the intermediate host of Dracunculus medinensis?

Dracunculiasis is caused by Dracunculus medinensis which is transmitted to humans by drinking unsafe water containing small crustacean copepods (Cyclops) containing the larvae of D. medinensis. Humans are the principal definitive host, and Cyclops is the intermediate host.

What are the types of filariasis?

There are 3 types of these thread-like filarial worms: Wuchereria bancrofti, which is responsible for 90% of the cases. Brugia malayi, which causes most of the remainder of the cases. Brugia timori, which also causes the disease.

What are the symptoms of Dracunculus medinensis?

Symptoms can include the following:
  • Slight fever.
  • Itchy rash.
  • Nausea.
  • Vomiting.
  • Diarrhea.
  • Dizziness.

How many types of filariasis are there?

There are three different filarial species that can cause lymphatic filariasis in humans. Most of the infections worldwide are caused by Wuchereria bancrofti. In Asia, the disease can also be caused by Brugia malayi and Brugia timori.

What is the causal agent of filariasis?

Causative Agents. The causative agents of lymphatic filariasis (LF) include the mosquito-borne filarial nematodes Wuchereria bancrofti, Brugia malayi, B. timori An estimated 90% of LF cases are caused by W. bancrofti (Bancroftian filariasis).

What are the risk factors of filariasis?

Common risk factors in the development of filariasis are exposure to mosquitoes for long time, getting bitten by them multiple times and people living in tropical areas for long time.
